The gang discusses two papers that look at the evolution of photosynthesis in different groups. The first paper looks at what might be the first fossil evidence of thylakoids, and the second paper finds evidence for photosynthesizing symbiotes in Devonian fossil corals. Meanwhile, Amanda is making a lasagna, James has a lot of opinions about lasagna (~10 minutes until we actually get to the paper), and Curt is all about those sponges. Up-Goer Five (Curt Edition): The friends talk about two papers that look at how some types of living things can make food from the sun. The first paper looks at these very very old things that are very very very small. Inside these things they find very very very small parts of things that are used today by some living things to help make food from the sun. This might be the oldest one of these things that we have ever found, and it makes it so that we can see how things might have gotten better at making food from the sun over time. The second paper looks at old animals that live in the big blue wet thing that all live close together and make big hard parts that make walls in the water. These old animals are like the ones we see today but they are a group that is not around anymore. Groups today have friends that help make food from the sun for them. This paper looks to see if the old animals had those friends (or friends like them) too. They find that animals today keep some bits of things they do not usually want so that their friends can eat them. This can be seen in the hard parts they make. When they looked at the hard parts of the old group of animals, they saw that they were doing this too. This means that these animals were keeping food for friends just like that animals we see today. References: Demoulin, Catherine F., et al.

One of the more whimsical names for a fossil site, come visit the Gogo formation of Western Australia as we go back 380 million years to visit a Devonian reef. Organisms that make an appearance include: stromataporoids, stromatolites, ammonites, Montecaris gogoensis, Conulariida, canthodians, tabulate coral, zooxanthellae, eurypterids, rugose coral, placoderms, and McNamaranspis kaprios.
Sarytogan Graphite Ltd (ASX: SGA) managing director Sean Gregory sits down with Proactive's Jonathan Jackson to discuss a new Exploration Licence Application (ELA) for copper porphyry mineralisation named Baynazar, just 20 kilometres west of the flagship Sarytogan Graphite Deposit in Central Kazakhstan. The 282 square kilometre Baynazar ELA is within the Central Asian Orogenic Belt (CAOB), known for hosting large copper-gold porphyry deposits. Historical Soviet work in the Baynazar area identified anomalies in copper, gold, silver, molybdenum, and tungsten. Sarytogan's exploration team is actively soil sampling and a high-resolution aeromagnetic survey will soon start. Gregory stated that this initiative is part of a broader strategy to develop a portfolio of copper projects to support the company's focus on battery metals. Kazakhstan is a significant copper producer with the CAOB region hosting notable deposits such as Bozshakol, Aktogay, Kounrad, Nurkazgan and Koksai. The Baynazar ELA is within a Devonian volcanic belt known for diverse mineralisation types. Historical exploration in the area reported more than 300 mineral occurrences, including gold and copper. The ELA, encompassing the Baynazar Caldera's western contact zone and two southern satellite calderas, shows promising signs of copper-porphyry mineralisation. Sarytogan has formed a new entity, Baynamys LLP, to manage its copper exploration assets. The company has received notification of ELA approval, contingent on environmental insurance payment. The company aims to build a portfolio of copper exploration properties in Kazakhstan, aligning with its battery metals strategy. #ProactiveInvestors #SarytoganGraphite #ASX #CopperExploration #KazakhstanMining #BaynazarProject #BatteryMetals #MineralExploration #CentralAsianOrogenicBelt #GeologicalSurvey #CopperPorphyry #SoilSampling #AeroMagneticSurvey #KazakhstanResources #MiningProjects #GreenEnergyTransition #CopperDemand #MiningIndustry #ExplorationLicence #GeologicalTeam #KazakhstanCopper #MiningNews #invest #investing #investment #investor #stockmarket #stocks #stock #stockmarketnews
(image source: https://www.deviantart.com/inkabg2/art/Ichthyotitan-severnensis-1049125055) Host Matthew Donald and guest co-host Allen Brooks discuss Ichthyotitan, the recently discovered big boy of the early Mesozoic seas that is up there with the biggest boys of all time, along with Perucetus and the modern blue whale. These weren't just boys. They were men. Whatever that means. Frick the patriarchy. From the Late Triassic, this 85-foot ichthyosaur was a voracious predator akin to an orca, meaning pretty much anything swimming about in this ocean was on the menu. Maybe every animal there should have just waddled onto land instead. Reenact the Devonian and crawl out of that dangerous sea. That's what I would've done, because I'm a coward. Hosted on Acast.

The gang discusses two papers that look at the morphology and ecology of early fishes. The first paper investigates a hypothesis for how the pectoral girdle could have evolved, and the second paper looks at the functional morphology of a Paleozoic jawless fish. Meanwhile, Amanda missed some context, James throws some shade, and Curt is annoyed by AI. Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals from a long time ago that live in water. The first paper looks at how part of the shoulder in people may have first started as a part of another part of the animal in these animals that lived in water a long long time ago. They find these parts of this animals from a long long time ago that they can use to see how the parts around the head grew. They use this to say that the shoulder parts may have started as a part of the thing these animals use to breath. The second paper looks at the mouth of a type of animal that lived in water a long long time ago that did not have a hard part in the mouth to move up and down and eat food. They use an animal they found with a lot of parts to see how these animals may have lived and what they could have eaten. They find that this animal could have been picking up food from ground at the bottom of the water or they could have been of taking food out of the water. This shows that even animals without a hard part to move up and down to eat food were finding ways to eat a lot of different things. References: Brazeau, Martin D., et al.

It takes our sun 220 million years to orbit around the middle of our home galaxy. But that kind of timescale can be difficult to picture. So, using the International Stratigraphy Chart as a guidance for what different time periods mean in terms of millions of years, let's zoom out to the scale of a galactic year and see what happened in Earth's prehistory one cycle ago, two and so on.

rWotD Episode 2447: Gauja Welcome to random Wiki of the Day where we read the summary of a random Wikipedia page every day.The random article for Monday, 15 January 2024 is Gauja.The Gauja River (Estonian: Koiva jõgi, German: Livländische Aa) is a river in the Vidzeme region of Latvia. It is the only large river of Latvia that begins and ends its flow in Latvia. Its length is 460 km, of which 93.5 km (approximately one-fifth) are in the Gauja National Park. In this part, the Gauja River flows through the Gauja valley, which is 1 to 2.5 km wide, and the maximum depth near Sigulda is 85 m. Thus, Gauja is the longest river of Latvia if only the parts of the river in the country's territory are counted. Daugava has only 367 km in Latvia, while the whole river is over 1000 km.The sandstone rocks on the banks of the Gauja and its adjoining rivers started forming 370 to 300 million years ago during the Devonian period.This recording reflects the Wikipedia text as of 00:55 UTC on Monday, 15 January 2024.For the full current version of the article, see Gauja on Wikipedia.This podcast uses content from Wikipedia under the Creative Commons Attribution-ShareAlike License.Visit our archives at wikioftheday.com and subscribe to stay updated on new episodes.Follow us on Mastodon at @wikioftheday@masto.ai.Also check out Curmudgeon's Corner, a current events podcast.Until next time, I'm Aria Neural.

LOOP 3.1: We introduce episode three of Life On Our Planet and discuss one of the most significant stories in the series. We're in agreement that lichens are the unsung heroes of the whole series and that Arthropleura is the crunchiest animal to ever exist. We talk about the ‘fishapod' Strepsodus and its locomotion. Life On Our Planet (LOOP) is a new 8-part series created for Netflix by Silverback Films and Amblin Television. This Steven Spielberg produced series, narrated by Morgan Freeman, is hugely ambitious in its scope, telling the story of life throughout the whole Phanerozoic Eon. Ancient organisms and environments are painstakingly recreated by the supremely talented Industrial Light and Magic, whilst modern natural history scenes add vital context to the story. This show has been worked on for six years, during which time countless papers were read and around 150 different palaeontologists contributed their time and knowledge. The whole production had culture of letting the scientific research dictate scenes, resulting in one of the most accurate on-screen representations of prehistoric life there has ever been. And how do we know all this? Well, our very own team members Tom Fletcher and Dave Marshall have been embedded within the LOOP team since day one! We are therefore in a totally unique position to reveal to you the work that went into this series, from both the production and research side of things. In this unofficial series, we've been granted exclusive access to many of the people responsible for creating LOOP, we explore what it takes to create a palaeontological documentary and we delve deeper into the science with some of the show's academic advisors. Each day, we will be releasing batches of interviews, each relating to a specific episode of LOOP. Image courtesy and copyright of Netflix.
LOOP 3.2: Producer Sophie Lanfear gives us our first insights into how documentaries are shaped. She tells us about the enormous scope of episode three and the difficulty of trying to fit in so many significant events. We analyse her use of emotion throughout the episode and she explains why she opted to use comedy. Finally, we look at the problem of anthropomorphism in documentaries.

(Piano music stops) Welcome to Ten Things I Like About… I'm Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. Some we'll find right out side our doors and some are continents away but all are fascinating. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won't regret it. This episode continues the coelacanth and the ninth thing I like about this animal is its fossil record. Throughout this series I've talked about the fossil's of the coelacanth and how they are sometimes called a ‘living fossil', so I thought we should take a few minutes to look at their actual fossil record. As we have discussed before coelacanths are old. The first coelacanths lived about 400 million years ago in the Devonian period. This was approximately 170 million years before dinosaurs roamed the earth. No matter how many times I say it, it still blows my mind! The fossil record of the coelacanth, just like everything else about this fish, is actually quite interesting. Throughout their long history coelacanths have been thought to be evolutionary conservative which essentially means they haven't changed much, but when we look a litter closer at the various fossils we see a different story. Our modern living coelacanths look like something that swam right out of ancient history, but throughout their existence they have had several body shapes. Let's look at the Devonian coelacanths. The best known Devonian coelacanth fossils come from the late Middle to early Late Devonian period. There are two early coelacanths that are well known, Gavinia and Miguashaia. These two genuses are considered primitive coelacanths because they are more like primitive lungfish and less like modern coelacanths in body form. What researchers look at to determine these classifications are the skull shape, the fin placement, and the tail. If we compare the skull shapes, in layman's terms, of Miguashaia and Latimeria (as a reminder that is our modern coelacanth) the Devonian era coelacanth's skull is broader and shorter, the body is shorter and more stout, and the tail is dramatically different. The Miguashaia tail technically has three parts like the modern coelacanth but the top fin is tiny while the bottom fin is much larger. The puppy dog tail portion of the tail that runs between the two fins sort of curves up a bit. The majority of the tail fin is below the midline and is square as opposed to the rounded tail of Latimeria. These are the most well known fossils from the Devonian period and they are fully formed enough that they can be placed in the coelacanth timeline based on body shape. But these are not the only fossils found from the Devonian era. There were fossils found in Australia from the early Devonian period suggesting coelacanths are even older than we previously thought. Researchers are hesitating to use these fossils when phylogenetically classifying coelacanths because it's only a lower jaw bone. The existence of a dentary sensory pore in the jaw proves it is a coelacanth, as modern day coelacanths, as well as other fossils throughout the ages, have dentary sensory pores also. Now, there have been approximately 80 species of coelacanth fossils described from the Middle Devonian to the Late Cretaceous. The Late Cretaceous dates from 360 million years to 70 million years ago. In the Cretaceous period, two families of coelacanths are represented through the fossils that we have found. One is Latimeriidae and Mawsoniidae. A scientific paper published in 2021, discussed the discovery of Cretaceous period mawsonid coelacanth fossils found in the Woodbine Formation in northeast Texas. The reason these fossils are important is that they expand the regional location of coelacanths. These are the first coelacanth fossils found in North America. We didn't know that they lived in the area of North America until these fossils were found. Researchers postulate that these coelacanths got here during the break-up of Pangea, but we need a lot more research before we have any solid theories. One of the things I wanted to know about ancient coelacanths was how big they were. It seems like when we go back in time, animals are always bigger than they are now. Like the dragonflies that used to be as big a VW Bug, sloths that were the size of an SUV, and sea scorpions the size of small sedan. Well, some of the coelacanth fossils that we have found are complete bodies and some have enough bones to extrapolate how big the fish was when they were alive. So we have a range from about two feet to thirteen feet! Our modern coelacanths seem to have settled somewhere in the middle. Coelacanths were believed to have gone extinct during the Late Cretaceous period. Today we know that's not true, but until 1938 we hadn't seen any or more importantly, we hand't found any younger fossils. The last record we had of the coelacanth came from the Cretaceous period. You may be wondering how this is possible, I know I was when I started researching this episode. I found a great article from UC Berkley that helped me understand what happened to the missing evidence of coelacanths for the last 60 million years. Lineages are important when studying the fossil record of any living things. Lineages are the unbroken chains of ancestors and descendants. They tell us who is related to whom. A ghost lineage occurs when a line of descent leaves no trace in the fossil record. This is what has happened to our beloved coelacanth. Now back to our question, how is this possible? How come we can't find fossil evidence of the coelacanth after the Cretaceous period. Living coelacanths reside in deep ocean waters near volcanic islands. To create fossils, whatever dies is preserved by layers of sediment and then exposed million of years later. If you are a deep water resident your fossils have to rise above sea level and eventually become exposed in an area where humans can find it, whether through natural erosion or paleontological digging. Well, most fossils are more than 70 million years old, so we haven't found younger coelacanth fossils yet because they're still hidden in the depths of the ocean where our modern coelacanths live. Coelacanths are considered a Lazarus taxon. A Lazarus taxon is a group of living beings that reappear after a long period during which they were thought to be extinct. The name is based on the biblical story of Lazarus who was raised from the dead. There are typically two characteristics shared by Lazarus taxons. 1- They have a limited geographic range. 2-They live in an area where fossils rarely form. This certainly sounds like the coelacanth to me. That is all for this penultimate episode of the coelacanth. The fossil record of this majestic fish is my ninth favorite thing about this long-lived animal. If you're enjoying this podcast please recommend me to friends and family and take a moment to give me a rating on whatever platform your listening. It will help me reach more listeners and give the animals I talk about an even better chance at change. Join me next week for the final episode about the coelacanth.

Predators and Prey in our Devonian Seas. It is here we see the first tetrapods — land-living vertebrates — appeared during the Devonian, as did the first terrestrial arthropods, including wingless insects and the earliest arachnids. In the oceans, brachiopods flourished. Crinoids and other echinoderms, tabulate and rugose corals, and ammonites were also common... and a mighty one-ton eating machine that ruled our ancient seas.
Nearly all parts of the human body can be traced back to fish, mainly to fish 380 million years ago.
The gang discusses two papers about trilobite evolution and morphology. The first paper looks at disparity and taxonomic trends of trilobites across the Devonian, and the second paper looks at the unique tridents of Walliserops. Meanwhile, Amanda makes a choice, James does some unique functional morphology, and Curt critiques tilapia. Up-Goer Five (Curt Edition): The friends talk about two papers that look at small hard animals that live in the water and some of them can roll into a ball. The first paper looks at how these animals looked over time. They look at whether or not these animals looked more different when there were more different types of these animals around. This is not usually the case, for lot of animals how different the animals in the group look to each other is not just because to there being more types of animals. For this group that some can roll into a ball, it seems like they look a lot more different when there are also a lot of different types of them. So when something kills a lot of them, they also lose what makes them different. After a really bad time for these animals, only one group was left and we saw that they kind of looked the same for a long time until they all died. The second paper looks at one of these types of animals that had a weird thing on its nose. They try and find out what it could have used this weird thing for because it is very big and it does not move on its own so it probably would not be good for a lot of things. They look at some other animals that have things on their nose they use to fight each other for space and girls. While these animals are very different, they show some ways that this thing on the nose look like these other animals. So maybe they used this thing on their nose to fight each other.

To continue supporting our state's producers, the West Virginia University Extension Small Farm Center will host its annual West Virginia Small Farm Conference from Feb. 22-25 at the Charleston Coliseum and Convention Center. Attendees will learn how to adapt their enterprises to meet the rising demand for local foods. There also will be more traditional offerings to help small farmers increase the profitability of their operations, from vegetable production to value-added products. Registration information and other conference details can be found at https://extension.wvu.edu/small-farm-conference. Read more: https://extension.wvu.edu/news/2023/02/06/2023-small-farm-conference #3 – From A-Z Animals – Long before West Virginia became a state, prehistoric animals called the land home. Check out some of these fascinating species: Dimetrodon lived around 295–272 million years ago during the Cisuralian Period. This unique extinct animal had neural spine sails with elongated spines protruding from the vertebrae. Scientists have found their tracks in West Virginia. The Edaphosaurus means “pavement lizard.” This large animal is one of the earliest known four-legged land-living vertebrate herbivores, weighing over 600 pounds and measuring up to 11 feet long. Archeologists have uncovered their fossils in West Virginia. A common and popular fossil hunting spot in the state is the Lost River. This is a roadside quarry near Wardensville. It is a 390-million-year-old Devonian reef that was perched at the Kaskaskia Sea. Read on to find more fossil hunting spots in Almost Heaven.

The earliest days of land plant evolution have long thought to have occurred in a hot house environment fueled by high CO2 levels. However, recent investigations suggest this may not have been the case and that small plants, not forests, had a massive role to play. Join me and Dr. Tais W Dahl as we travel back over 400 million years to the Devonian Period and discuss how small relatives of lycopods may have altered Earth's atmosphere to such a degree that the Devonian climate may have been more familiar than once hypothesized.

Our JUNEiversal Monsters series appropriately concludes with a discussion of the last of the original classic Universal Monsters, THE CREATURE FROM THE BLACK LAGOON (1954)! The timeless story of a lonely humanoid Devonian who is forced to fight back against a group of home invaders who harass and persecute him simply because he's different. Nathan, Eric, and Dan dive into the film to discuss why the Gill-man stands out as the best-designed monster and how the film elegantly conveys so much about the creature through the physical performances of Ben Chapman and Ricou Browning. We also talk about the gorgeous underwater photography, why bodies of water are so frightening, the environmental message at the heart of the film, the portrayal of women in 50s sci-fi, Gill-man's sweet cavernous bachelor pad, and speculate on the love life of this poor creature who is clearly just looking for companionship in a small pond like the Black Lagoon. So destroy your speargun, put away the rotenone, and next time you see a Gill-man approaching with arms outstretched, don't be afraid. Instead, reach out and give him a big ol' hug because what he really needs is a little love and understanding. Much like how you need to understand our love for the Gill-man by listening to our review of Jack Arnold's CREATURE FROM THE BLACK LAGOON!

The gang discusses two papers that look at topics in biogeography. The first paper reviews the concepts of cradles and museums (and whether we should retire those concepts), and the second paper explores traditionally defined Devonian bioregions. Also, the gang uses the broad topics from both of these papers to talk about a lot of tangentially related topics. Meanwhile, James has strong opinions about what is edible, Curt disagrees, and Amanda remains painfully neutral throughout. Up-Goer Five (Curt Edition): Our friends talk about two papers that look at the ways we talk about the places animals come from. The first paper is looking at two words that we use to talk about these places. The words are used to talk about places where new living things come from and places where living things can stick around for a long time. The paper talks about how those words were first used and why they came up in the first place, and then talks about how we have changed what we mean by those words in ways that maybe is not helping us better know about places. They talk a lot about how the way these words were first used has now been forgotten, and so the way we use them today makes things a little too simple. Instead of focusing on finding the simple form of these places, we should be looking at the ways the world works which can make some areas better for new living things to form or for old living things to stick around. The second paper looks at whether or not animals that are close to each other come from the same places through time. Are there places that have their own types of animals which all come from just those places for a really long time. They look at the whole world a long time ago when people have said that they can find these groups of animals that all come from one place. They look at a lot of other studies and use those studies to run another study. They find that some of the smaller areas may show what people have said in the past, but most of the big areas do not have this long time where all the animals are from this one place. The reason why it may have looked like that in the past may be because of how we got those old animals and the types of people who were allowed to go out and get those old animals in the past.

The gang discusses two papers that look at unique morphological features of fossil animals. The first paper looks at a new Ankylosauria species that complicates our understanding of the group's evolution, and the second paper investigates the structure of the trilobite schizochoral eye. Meanwhile, James endures formatting, Amanda starts her new religion, and Curt finds the puns no one else sees. Up-Goer Five (Curt Edition): Our friends talk about two papers where we can see cool parts of animals that are very old and tell us something about how these animals lived in the past. The first paper is looking at a big angry animal with no hair who lived a long time ago and is part of a group that has a long part coming off its bottom with a hurt causing part at the end. There are two close groups of big angry animals that have this long part with a hurt causing part at the end. One group has a lot of points and the other group has a part that is hard. This animal makes it more interesting because it has parts that look like animals with the hard end and animals that have the point end. The animal is still a part of the group with the hard end, but it shows that some of the things we see with the animals with the point end were also found in some animals with the hard end. The second paper looks at the eyes of an old group of animals who lived in the water and had their hard parts on the outside as well as legs and bodies that are broken into parts. A lot of work had been done on the eyes of some of these animals that have strange eyes where there are less round bits where the eyes can see through than in others, but the round bits are larger. This paper finds some old work and also adds to that work to say that maybe these eyes with large but less round bits might have acted like a whole lot of eyes under each of these round bits. So while most eyes for this group have tiny round bits which act as tiny eyes, this group with the large round bits might have had tiny eye parts under each of the large round bits. These large round bits may have acted as many tiny eyes. References: Soto-Acuña, Sergio, et al. "Bizarre tail weaponry in a transitional ankylosaur from subantarctic Chile."

This conversation with Dr. Nancy Chow, geologist at the University of Manitoba, is about the organics in the Duvernay and Keg River Formations. The discussion focuses around Nancy Chow, Jack Wendte, and Lavern D. Stasiuk's scientific research paper titled “Productivity versus preservation controls on two organic-rich carbonate facies in the Devonian of Alberta: sedimentological and organic petrological evidence”. Some highlights include evidence for organic matter preservation due to bottom water anoxia vs high organic productivity.

The Flannelcasters talk about the potential causes of the late Devonian extinction, as well as it's extent.
Australian palaeontologist Professor John Long has spent a lifetime expanding what we know about ancient animals, especially fish from the Devonian age, about 400 million years ago. John grew up in Victoria and was educated at Monash University. His fossil expeditions have taken him throughout Australia and to places as diverse as Vietnam, Iran and Antarctica. His ground-breaking discoveries include contributing to our understanding of how reproduction evolved, and the reasons behind global mass extinctions. Science outreach is an important part of John's work and he's written more than 20 popular science books. Recently the tide of authorship turned the other way, and John became the subject of a new book in the Aussie STEM stars series. We asked the book's author, Dr Danielle Clode, who's also a Cosmos contributor, to talk to John about his life and work.Find the science of everything at the Cosmos Magazine website Subscribe to Cosmos Magazine (print) or the Cosmos WeeklyWatch and listen to all our Cosmos BriefingsSpecial 10% discount on Cosmos magazine print subscriptions (1 or 2 year), or 1 year Cosmos Weekly subscriptions for Cosmos Briefing podcast listeners!

Episode 34 Well, we did it. We went full throttle and geeked out discussing all things Devonian. Have you ever found yourself saying the Devonian was SOOO boring? Nothing was going on besides something about fish and that is about it! If this sounds like you, boy do we have an episode for you! When was the Devonian you ask? The Geologic Period of the Devonian Period is part of the Late Paleozoic Era that follows the Silurian Period and precedes the Carboniferous Period, spanning between about 419.2 million and 358.9 million years ago. The developments of the Earth system during the Early Devonian to Middle Permian interval record the dynamic interplay of its geo-, hydro-, bio-, and atmospheric systems. Most of the Devonian Period was a time of exceptionally high sea-level stand and inferred widespread equable climates, but glaciations occurred immediately before its end in the south polar areas of Gondwana (South America, Central, and South Africa). There is even evidence for contemporaneous mountain glaciers in tropical latitudes (in the Appalachians of eastern North America). The Early Devonian, really to the Middle Permian, 260 Ma, was an interval of major tectonic, climatic, oceanic, and biotic changes. The collision of Laurasia and Gondwana led to global-scale tectonic activity and the formation of the supercontinent Pangea, and the spread of vascular land plants resulted in a huge increase in organic carbon burial and atmospheric CO2 drawdown. There was a Late Paleozoic Ice Age (LPIA) that commenced with short-lived glaciations at the Frasnian-Famennian boundary (FFB) and the Devonian-Carboniferous boundary (DCB) that coincided with two first-order mass extinctions, although many minor biocrises also occurred during this interval. Most present-day continental areas and shelves were grouped in one hemisphere, creating a giant “Proto-Pacific” or Panthalassa Ocean, whose margins are poorly preserved in allochthonous terrains. Allochthonous just means sediment or rock that originated at a distance from its present position. And, following the tectonic events of the Caledonian Orogeny of Laurasia, many “Old Red Sandstone” terrestrial deposits formed. Sit back and enjoy as we stumble our way through all the difficult words and the world of the Devonian.

For this episode of The Backpacker's Guide To Prehistory, host David Mountain travels all the way back to the Devonian period, 419-359 million years ago. In this weird world of giant fungi and armour-plated fish, what creatures should you look out for? Where should you pitch your tent? And should you really take a dip in Devonian waters?Providing the answers are two Devonian experts: Dr Sandy Hetherington, a palaeobotanist at the University of Edinburgh (https://www.ed.ac.uk/profile/dr-sandy-hetherington; https://twitter.com/Sandy_Heth), and Dr Alice Clement, a palaeontologist at Flinders University (https://www.flinders.edu.au/people/alice.clement; https://draliceclement.com/; https://twitter.com/DrAliceClement). Massive thanks to Sandy and Alice for sharing their advice. If you're interested in the evolution of forests and tetrapods - and I know you are - then make sure to check out their research!

It's the next in our short series of episodes about mass extinctions! Don't worry, it won't be boring, because we're going to learn about a lot of weird ancient fish too. Further reading: Titanichthys: Devonian-Period Armored Fish was Suspension Feeder Behind the Scenes: How Fungi Make Nutrients Available to the World Dunkleosteus was a beeg feesh with sharp jaw plates that acted as teeth: Titanichthys was also a beeg feesh, but it wouldn't have eaten you (picture from the Sci-News article linked above): Pteraspis: NOSE HORN FISH: Cephalaspis had no jaws so it couldn't chomp you: Bothriolepis kind of looked like a fish in a mech suit: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Here’s the second in our small series of episodes about extinction events, this one the Late Devonian extinction. We’ll also learn about some weird and amazing fish that lived during this time, and a surprising fact about ancient trees. The Devonian period is often called the Age of Fish because of the diversity of fish lineages that arose during that time. It lasted from roughly 420 million years ago to 359 million years ago. During the Devonian, much of the earth’s landmasses were smushed together into the supercontinent Gondwana, which was mostly in the southern hemisphere, and the smaller continents of Siberia and Laurussia in the northern hemisphere. The world was tropically warm, ocean levels were high, and almost all animal life lived in the oceans. Some animals had adapted to living on land at least part of the time, though, and plants had spread across the continents. The first insects had just evolved too. Shallow areas of the ocean were home to animals that had survived the late Ordovician extinctions. There were lots of brachiopods, bivalves, crinoids, trilobites, and corals. Eurypterids were still thriving and ammonites lived in deeper water. But while all these animals are interesting, we’re mainly here for the fish. The fish of the Devonian were very different from modern fish. Most had armor. Way back in episode 33 we talked about the enormous and terrifying dunkleosteus, which lived in the late Devonian. It might have grown up to 33 feet long, or 10 meters. Since we still don’t have any complete specimens, just head plates and jaws, that’s an estimate of its full size. However long it grew, it was definitely big and could have chomped a human in half without any trouble at all. It’s probably a good thing mammals hadn’t evolved yet. Instead of teeth, dunkleosteus had jaw plates with sharp edges and fanglike projections that acted as teeth. Another huge fish from the Devonian is called titanichthys, which might have grown as long as dunkleosteus or even bigger, but which was probably not an apex predator. Its jaw plates were small and blunt instead of sharp, which suggests it wasn’t biting big things. It might not have been biting anything. Some researchers think titanichthys might have been the earliest known filter feeder, filtering small animals from the water by some mechanism we don’t know about yet. Filter feeders use all sorts of adaptations to separate tiny food from water, from gill rakers to baleen plates to teeth that fit together closely, and many others. A study published in 2020 compared the jaw mechanisms of modern giant filter feeders (baleen whales, manta rays, whale sharks, and basking sharks) to the jaw plates of titanichthys, as well as the jaw plates of other placoderms that were probably predators. Titanichthys’s jaws are much more similar to those of modern filter feeders, which it isn’t related to at all, than to fish that lived at the same time as it did and which it was related to. Titanichthys and dunkleosteus were both placoderms, a class of armored fish. That wasn’t unusual, actually. In the Devonian, most fish ended up evolving armored plates or thick scales.

The gang discusses two papers that look at interesting new arthropod fossil finds. The first paper is the discovery of a new early arthropod which complicates our understanding of their evolution, and the second paper is a large deposit of trace fossils which could be caused by mass arthropod molting. Meanwhile, James has issues with formatting, Amanda’s cat is a butt, and Curt has some important legal disclaimers to share. Up-Goer Five (Curt Edition): Our friends talk about some animals with many legs that lived in the water and lose their hard skin a long time ago. The first paper is talking about a new type of these animals from a very long time ago which has a lot of different parts on it which look like parts that are found in different animals from around that same time. It has really long arms and also five eyes. These very different parts that don't look like they go together means that it can tell us a lot about how these animals with many legs that lose their hard skin have changed over time. And then our friends run out of things to talk about. The second paper looks at marks left in the broken up bits of rock. These marks were probably made by one of these animals with many legs that was in the middle of breaking out of its hard skin. The marks look the animals put their bottoms in the ground as they broke out of their skin. Also, the type of broken up bits of rock leads the people who wrote the paper to think that these animals might be moving to place that is not great to live in in order for them to be safe when they break out of their skin. They find lots of marks in the broken up its of rock all at the same time. This might mean that the animals that made these marks were able to move into these places just to break out of their skin.
