The gang discusses two papers about fossil cephalopods. The first paper uses new methods to reassess the taxonomy of what was previously considered to be the oldest octopod, and the second paper uses preserved beaks to reconstruct large body sizes of Mesozoic octopods. Meanwhile, Amanda keeps it within Michigan, James brings up THE cephalopod talk, and Curt ascends. Up-Goer Five (Curt Edition): Our friends talk about two papers that look at animals with many arms and a sharp mouth. The first paper looks at some parts of a very old animal with many arms. People thought that it might be an animal with many arms that does not have a hard home to live inside and carry around with it. But this paper looks over that animal and finds that the animal is an animal that lived in a hard home that it carried, but after it died it fell out of that home when it started to fall to pieces. The second paper looks at another animal with many arms and uses the size of the mouth to see how big the animal was. They find that these animals with many arms were very very big. They also say that this means they were really sharp which the friends talk about a lot. References: Clements, Thomas, et al.

The first is the black-naped pheasant-pigeon. The word nape refers to the back of the neck, and this bird does have a black neck. It's a dark blue-black all over, in fact, with reddish-brown wings, a red bill, red eyes, and long yellow legs. It looks almost identical to the other three species of pheasant-pigeons known, although some scientists think they're subspecies. Those three are the white-naped, the green-naped, and the grey-naped pheasant-pigeons, and if you're wondering if the spot of color on the back of the neck is the easiest way to tell these birds apart, you are exactly right. All four species are native to parts of New Guinea or small islands nearby. Pheasant-pigeons look a lot like pheasants and are about the size of a chicken, although they're actually pigeons. They live in forests and eat seeds and fruit, and while they can fly they spend almost all of the time on the ground. We don't know a whole lot about them because they're so secretive and hard to spot in the wild, although the white-naped and green-naped birds are sometimes kept in zoos. In the case of the black-naped pheasant-pigeon, all scientists knew about it was from two specimens collected in 1882. It hadn't been seen since…until September of 2022. A team of scientists visited Fergusson Island off the east coast of Papua New Guinea in September, as part of a worldwide collaboration of scientists called The Search for Lost Birds. This is similar to the Search for Lost Frogs that has been active for over a decade, discovering lots of new amphibians and rediscovering even more. The 2022 search was actually a follow-up to a 2019 expedition that had failed to find the bird, although it did make other discoveries. In 2022, the team brought more people and equipment, determined to make the best effort possible to find the black-naped pheasant-pigeon. They consulted with local hunters to find the best places to search, and talked to lots of residents to see if anyone had seen one, and spent day after day hiking through forested mountains. For weeks they had no luck. Then, in a remote mountain village, they finally met some people who were familiar with the bird. One man led them to the right part of the forest and they set up camera traps, but at that point they only had a few days left before they had to leave the island. When they checked the pictures captured by the camera traps, though, they'd found it! Two of the cameras had taken pictures and video of what were definitely black-naped pheasant-pigeons, and since the cameras were several kilometers apart the pictures were probably of different individuals. The black-naped pheasant-pigeon wasn't extinct, which means it can be protected. Habitat loss, especially from commercial logging, and feral domestic cats are the two main threats to birds in the area. The other bird we're going to talk about today hasn't been seen in even longer: 119 million years, in fact. The article about this fossil was only released a few days ago as this episode goes live. You can check the show notes for links to this article and a good one about the pheasant-pigeon too. Paleontologists discovered the bird's fossil remains in northeastern China, in fossil beds that contain incredibly well-preserved animals and plants. The Jiufotang Formation in China dates to the early Cretaceous, between about 122 and 119 million years ago, and researchers think it's from an area that was once a shallow lake surrounded by forests. Every so often, a nearby volcano would erupt and the resulting ash would fall into the lake, causing anoxic conditions that helped preserve animals that died and sank into the mud at the bottom of the lake. There are lots of fish, pterosaurs, birds, and dinosaurs among the fossils discovered, most of them small but a few quite large. This includes a type of tyrannosaur that probably grew around 33 feet long, or 10 meters. A few early mammals have been discovered too. In one case, the remains of 40 individual birds were found on one big slab of stone, and scientists think an entire flock of birds was killed by a volcanic ashfall or poisonous gases from the volcano. The newly described fossil we're talking about today was almost complete and almost completely articulated, preserved with the impression of feathers around its body. The bird has been named Confuciusornis shifan and was a little smaller than a modern crow. It had a toothless beak and a short tail, although it probably had long tail feathers. Other Confuciusornis species have been discovered with the impressions of long tail plumes. All of the Confuciusornis fossils discovered so far were birds that could fly well but probably nowhere near as well as any bird today. But C. shifan had an adaptation in its wings not seen in any other bird, living or extinct. It had a small extra bone in the wing that acted like a cushion and probably helped the wings withstand the stresses of flight. The most interesting thing about the different Confuciusornis species is that if we could go back in time and see them when they were alive, they probably wouldn't have looked unusual to most people, except to bird experts who would instantly freak out. For the most part, they just looked like birds. Some specimens show preserved melanosomes under electron microscopy that indicate the feathers were various colors including white, brown, red, and black. There's even evidence of a pattern of spots and streaks on some feathers. Their feet were adapted for perching the way many modern songbird feet are. But Confuciusornis wasn't a direct ancestor of modern birds as far as we know. Even though we have lots of beautifully preserved Confuciusornis fossils, the fossils can only tell us so much. We have a pretty good idea of what the birds looked like, but we don't know much about how they lived. One specimen was found with the remains of a tiny fish inside its body, so researchers think the birds may have eaten fish or might have just been omnivores that weren't picky about what they ate. One specimen was found with an egg beside it that was the right size to have fit through its pelvic opening, but we can't know for sure if the egg belonged to the bird or was from another bird and just happened to have settled near the dead bird when it fell in the water. Still, even though we only have fossil remains, that's much better than having no knowledge of these early birds at all. Thanks for your support, and thanks for listening!
What if I were to say this: Image this: Many, many years ago on this very planet we walk today, giant lizard-like animals roamed, roared, and raged. What if I also told you that they liked to eat plants, insects, and even each other. And, what if I had to break the news to you that these "creatures of the Cretaceous (era)” all were violently killed - wiped off the face of the Earth - by an interstellar rock... Sounds unbelievable right? Well… I hate to be the bearer of bad news, but its all true. All of it. But, even though their story is one of eventual death and destruction, their memory and legacy will always live on here as we take a moment to celebrate: The Age of the Dinosaurs.
Bu bölümde insanlığın evrimsel yolculuğuna ve doğayla kurduğumuz o kadim, sancılı ilişkiye odaklanıyoruz. Paleolitik çağın zorlu hayatta kalma mücadelelerinden, modern dünyanın 'istilacı' türü olmamıza giden süreci; termitlerin toplumsal disiplininden, fitoplanktonların sessiz çöküşüne kadar biyolojik bir perspektifle inceliyoruz. Kendi yarattığımız bu kokuşmuş düzenin içinde, aslında kibrimizle kendi sonumuzu nasıl hazırladığımızı sorguluyoruz. Bizler gerçekten gezegenin hakimi miyiz, yoksa sadece geçici birer misafir miyiz?

The gang talk about two papers about extraordinary dinosaur fossils and the unique information that can be gleaned from them. The first paper looks at fossil skin data on a Cretaceous iguandodontian, and the second paper uses an exceptionally complete specimen to demonstrate the reality of Nanotyrannus. Meanwhile, James classifies, Amanda imagines T-rex, and Curt brings a unique energy. Up-Goer Five (Curt Edition): The friends look at two papers about big angry animals that everyone loves to talk about. The first paper is about the skin of one of these big angry animals. This skin has weird bits on it that are not like the weird bits we see in a lot of other animals that are close to these big angry animals. These bits do not look like the bits that would be used to stay warm or to move into the air. These bits look like they might hurt. The second paper looks at a lot of stuff from one big angry animal that has been said by people in the past is just a young one of another big angry animal. The paper looks at the parts of this animal, how this animal grew, and a lot of other things to show that, no, this animal is not this other animal. This animal is its own type of animal.

While the new material is exciting, the larger crest is not surprising given the species' known display features. The new locality in Niger, further inland than previous finds, suggests Spinosaurus may have followed rivers inland, similar to other water-affiliated animals. A new paper confirms long-held beliefs about spinosaur evolution, including sexual selection, wading behaviour, and multiple evolutionary phases. The discovery of a new rhabdodontid skull, with clear ceratopsian characteristics, suggests that some previously identified rhabdodontids were actually early ceratopsians. This finding supports the idea that ceratopsians were present in Europe during the Cretaceous, filling a gap in the fossil record. Apologies for audio quality - was a bit rushed!

Extinction is coming fast for Dinoland, so many areas have closed and the remainder will come to an end quickly. We bid our final adieu by digging for lessons to be learned from this corner of Disney's Animal Kingdom park. They serve to help us understand what worked and didn't work not just in this land, but for people trying to perhaps not build a theme park, but build organizations and take them to the next level. We may not be going back to the Cretaceous period, but we are considering how this land became what it became. And we are looking at some very intricate details that shape our understanding of how life must have been here in Diggs County. Join us as we go digging' for Insights at Dinoland. ________________________________________________________ Disney Insights YouTube Page--Check it out and subscribe.

While the origins debate is basically a religious debate, many people have been taught that evolution is science and creation is religion. But even according to the evolutionists' own rules of science, evolution is not good science. Let's examine the claims of evolution in light of what science knows today.Life has never been seen to develop from nonliving materials. Yet evolution says it did. Mutations, said by evolutionists to have created all the kinds of living things, have never been seen to produce one creature who was more complex or better able to survive. Then again, the moon has moonquakes, a magnetic field and internal heat—all indications that it is far younger than evolutionists believe. The Cretaceous limestone was produced from sediment in water and extends in one continuous band from Northern Ireland through Europe and Asia to Australia. This suggests that the entire area was beneath the sea all at the same time, yet evolution refuses to accept Noah's Flood as a global and historical event.If language evolved, why are the most ancient languages the most complex? If religion evolved, why do the most ancient forms of religion worship one God, a Creator, while later forms of the same religions have many gods—who are much more like human beings?I could list many more examples showing that only the Bible's account of history makes sense in light of what we know today.Psalms 111:10"The fear of the LORD is the beginning of wisdom; A good understanding have all those who do His commandments. His praise endures forever."Prayer: Dear Lord; the very stones cry out that You are indeed Creator and Almighty God. Help me to add my voice to this witness, and tell others of Your forgiving love in Jesus Christ. In His Name. AmenREF.: Brown, Walter T. The scientific case for creation: 116 categories of evidence.

Summary: Tua-what? Join Kiersten to find out what the tuatara is. For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean Show Notes: “Sphenodon punctatus (Tuatara)” Animal Diversity Web: https://www.animaldiversity.org Music written and performed by Katherine Camp Transcript (Piano music plays) Kiersten - Welcome to Ten Things I Like About… 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. My name is Kiersten and I have a Master's Degree in Animal Behavior and did my thesis on the breeding behavior of the Tri-colored bat. I was a zookeeper for many years and have worked with all sorts of animals from Aba Aba fish to tigers to ravens to domesticated dogs and so many more in between. Many of those years were spent in education programs and the most important lesson I learned was that the more information someone has about a particular animal the less they fear them. The less they fear them the more they crave information about them and before you know it you've become an advocate for that misunderstood animal. 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. The next unknown animal I have chosen takes us on a journey through ancient times. We haven't ventured this far back in time since we talked about the coelacanth. Welcome to the first episode of tuatara. The first thing I like about this unknown animal is their continued existence. You may be saying tau-what? Tuatara is our next animal. Let's jump right into the classification which will answer some of your initial questions. Like what the heck is a tuatara? Remember classification is the way scientists identify different living things including animals and plants so that we all know who exactly we are talking about. The classification of the tuatara is as follows: Kingdom: Animalia (that's the animals) Phylum: Chordata (chordates) Subphylum Vertebrata (that's the animals that have an internal skeleton or the vertebrates) Class: Reptilia (that's the reptiles) Okay! Now we're getting somewhere. Tuatara must be a reptile! Order: Rhynchocephalia (there is only one reptile in this order) You guessed it! The tuatara. Family: Sphenodontidae Genus: Sphenodon Species: punctatus The scientific name for the tuatara is Sphenodon punctatus. There are two recognized species of tuatara. The Brother's Island Tuatara is Sphendon guntheri. The first tuatara, Sphenodon punctatus, is referred to as the Northern tuatara. Now, we know this animal is a reptile, but what does it look like? Is it small? Is it large? Is it green, brown, or purple? Tuatara can be green, olive, or brick red in color. Their adult size ranges from 15 inches, or 40 cm, in the female to 24 inches, or 60cm, in the male. Both male and female have two crests of dull-edged spikes that travel down the back of the head to the neck with the second on the middle of the back along the spine. The male's crests will be larger than the female's which helps to distinguish the sexes from each other. They have four short legs and a long tail that usually exceeds the length of their body. They look a lot like a lizard, but they aren't exactly lizards. We will dissect that statement in a future episode. They have no external earhole but they do have ears. They have two eyes that can focus independently and are placed on the sides of the head. They have a variety of scale structures along their body giving them a dinosaur-ish look. There are a few attributes that set tuatara apart from other species of reptiles. One of those is their third eye. Yes, they have a third eye, a parietal eye, right in the middle of the top of their head. It has a retina and is functionally similar to a normal eye. In juveniles it is exposed but as it ages a scale grows over it. We are currently uncertain of its purpose. Another attribute that sets the tuatara apart is their teeth. Tuatara teeth are fused to the jaw bone, unlike any other toothed reptile. This is an acrodont tooth structure. This speaks to the age of this species of reptile. The tuatara is the only living specimen of Rhynchocephalia. All of them, expect the tuatara, went extinct in the late Cretaceous period. We will dive into this topic in a future episode. One last thing about the tuatara before we end the first episode of this new series. One tuatara, many tuatara. When talking about the tuatara, the singular is the same as the plural. Thank you for choosing to start this series with me. We are going to have a fun time with the tuatara. My first favorite thing about them is them! 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 to find out where the tuatara are found. (Piano Music plays)
AP correspondent Ben Thomas reports scientists have found a very large window into the Cretaceous period.
The gang discusses two papers that are about dinosaurs, and that is all that connects them! The first paper investigates community structure during the Cretaceous, and the second paper describes a well preserved "mummy" of a duck-billed dinosaur. Meanwhile, Amanda is doing well (really she is now), Curt makes an awkward segue, and James has not seen Tremors. Up-Goer Five (Curt Edition): The friends talk about two papers about big angry animals from a long time ago. The first paper looks at how many types of big angry animals were in a place before something bad happened and all the big angry animals died. Lots of people have said that the big angry animals might have been in trouble before the bad thing happen, and lots of other people say that they were probably not in trouble but we just don't have a lot of places that have the big angry animals in them for us to look and see what is happening at that time. This paper looks at a place and shows that it was during the time we want to see and that the types of animals in a place were a lot like the types of animals in a place before, so that means that it does not look like these big angry animals were having a bad time before the bad thing happened. The second paper looks at soft parts of a big angry animal that was dried out so that you can see skin and other bits under the skin. This lets the people find out what the feet look like for this animal, and other bits about how it moved. References: Flynn, Andrew G., et al.

Todo el mundo sabe que los dinosaurios desaparecieron de la Tierra hace 66 millones de años porque chocó con nuestro planeta un gran asteroide o cometa, ¿verdad? Bueno, ésa ha sido una afirmación aceptada por muchos, pero también disputada por otros, a lo largo de los últimos 35 años. Es cierto que hubo un gran impacto hace 66 millones de años, y que coincidió con la desaparición de los dinosaurios (excepto las aves), pero también es cierto que ese periodo coincidió con una época de potente vulcanismo que pudo "envenenar a fuego lento" a los dinosaurios. ¿Fue el meteorito la causa principal de la extinción o fue sólo un último acto, uno especialmente espectacular, dentro de una tragedia más larga? Este debate se ha mantenido abierto desde el descubrimiento del cráter de Chicxulub a principios de la década de 1990, pero parece que está zanjándose en los últimos años gracias a una serie de descubrimientos en estratos muy cercanos al momento de la extinción. Hoy os presentamos el último de esos estudios, en el que los paleontólogos logran reconstruir los ecosistemas del sur de los Estados Unidos en los miles de años previos a la extinción. En él descubren que los dinosaurios parecían estar en buen estado de salud, lo cual apoyaría la idea de que el meteorito fue fundamental para su extinción. Hablamos de todo ello con uno de los autores del artículo: Jorge García Girón, que es ecólogo y profesor en la Universidad de León. Si queréis leer el artículo al que nos referimos, se trata de "Late-surviving New Mexican dinosaurs illuminate high end-Cretaceous diversity and provinciality ", de Andrew G. Flynn et al. Podéis encontrarlo aquí, y es de acceso libre: https://www.science.org/doi/10.1126/science.adw3282 A lo largo del programa también mencionamos el libro "The Reinvention of Science", de Vicent Martínez et al, en el cual (entre otras cosas) se narra la historia del debate entre vulcanistas e impactores. Por ahora sólo está publicado en inglés, pero a lo largo de 2026 está previsto que salga también en español. Lo podéis encontrar aquí: https://www.worldscientific.com/worldscibooks/10.1142/q0394#t=aboutBook Si os interesa este tema os recomiendo mucho que repaséis el episodio s02e18 de Aparici en Órbita, en el que ya abordamos este debate sobre las causas de la exitnción de los dinosaurios. En aquel caso hablamos de las evidencias geológicas, que también parecen apunar a que la influencia de los volcanes había menguado en el momento de la extinción. También podéis aprender más sobre la extinción en los capítulos s04e14, s01e20 y s02e42, y en dos episodios de nuestro pódcast hermano, La Brújula de la Ciencia: el s10e36 y s08e26.

Welcome back to Cretaceous Craft, the ultimate Minecraft dinosaur survival series!
Paleontologist and author Armin Schmitt returns to the show where we explore two remarkable dinosaur discoveries that are reshaping what we know about life millions of years ago.From the longest dinosaur trackway ever uncovered in Oxfordshire, England, to the first-ever discovery of fossilised gut contents inside a sauropod in Australia, Armin shares the science — and the stories — behind these once-in-a-lifetime finds.We hear how ancient footprints reveal the daily lives of long-necked giants, what a 100-million-year-old meal can teach us about dinosaur diets, and how new technologies are helping paleontologists read the Earth's oldest stories written in stone.Armin takes us on a journey through deep time — from Jurassic lagoons to Cretaceous forests — filled with curiosity, wonder, and the enduring human desire to understand the world beneath our feet.
The Cretaceous insects in the family Umenocoleidae have been difficult to classify, but for Soo Bin Lee they are a window into one of the most interesting periods of our prehistoric world. While closely related to the modern cockroaches in order Blattodea, fossil Umenocoleids have been found and researched across the world and found to be present across a larger portion of geologic time than expected. They're linked to the Cretaceous Terrestrial Revolution, an important period of change when angiosperms, or flowering plants, exploded in diversity and prevalence and changed the development of insects as a result. By examining the tiny and delicate wing venation of fossils, Lee and his coauthors were able to uncover and untangle a new chapter in our knowledge of prehistory. Listen in as Lee draws us into the world of prehistoric creatures, environmental change, and the beauty and complexity of wings.Soo Bin Lee's paper “A new Albian genus and species and two other new species of Umenocoleidae (Dictyoptera) from South Korea” is in volume 166 of Cretaceous ResearchIt can be found here: https://doi.org/10.1016/j.cretres.2024.106013A transcript of this episode can be found here: Soo Bin Lee - TranscriptNew Species: Umenocoleus minimus, Pseudoblattapterix weoni, Petropterix koreaensisBe sure to follow New Species on Bluesky (@newspeciespodcast.bsky.social) and Instagram (@NewSpeciesPodcast) and like the podcast page on Facebook (www.facebook.com/NewSpeciesPodcast).Music in this podcast is "No More (Instrumental)," by HaTom (https://fanlink.to/HaTom)If you have questions or feedback about this podcast, please e-mail us at NewSpeciesPodcast@gmail.comIf you would like to support this podcast and enjoy bonus episodes, please consider doing so at https://www.patreon.com/NewSpeciesPod

For over forty years, Dutch geologist and paleontologist Jan Smit has been at the center of one of the most profound scientific detective stories of our time: the investigation into the mass extinction that ended the reign of the dinosaurs 66 million years ago. Known as the Cretaceous-Paleogene (K-Pg) extinction, this event wiped out nearly 75% of all species on Earth, from towering dinosaurs to microscopic marine life, and cleared the way for the rise of mammals and, eventually, humans. Early in his career, Jan Smit became intrigued by a thin layer of clay found in rock strata across the globe, precisely at the boundary between Cretaceous and Paleogene sediments. This layer, unusually rich in the rare element iridium, held clues that would eventually transform our understanding of planetary history. Working alongside Luis and Walter Alvarez and others, Jan helped develop the hypothesis that a massive asteroid impact, rather than volcanic activity or gradual climate change, was the primary cause of the extinction. In this episode, we explore the extraordinary evidence for that theory: global patterns of shocked quartz, tsunami deposits, a massive crater buried beneath the Yucatán Peninsula, and the sudden disappearance of entire ecosystems in the fossil record. Jan walks us through decades of fieldwork and analysis that revealed the incredible violence and planetary consequences of the impact, a blast more powerful than a billion Hiroshima bombs, throwing Earth into a global winter. But this is more than a forensic tale of catastrophe. It's a window into the fragility and resilience of life, the interconnectedness of geological and biological systems, and the awe-inspiring forces that shape the story of our planet.

HEADLINE: Knuckle Walkers and the Discovery of Color in Cretaceous Dinosaurs BOOK TITLE: Other Lands, a journey through Earth's extinct worlds GUEST AUTHOR NAME: Thomas Halliday 200-WORD SUMMARY: This section focuses on the Cretaceous period, 125 million years ago, exploring the heyday of non-avian dinosaurs. Herbivores, such as the 17-meter-long titanosaurs, are described as "knuckle walkers" because they lost their finger bones and supported their immense weight on modified hand bones. The forests at this time were primarily composed of conifers, ginkos, and ferns, as flowering plants were only just beginning to emerge. The site of Liaoning, China, provides extraordinary preservation, allowing scientists to determine dinosaur coloration. By examining melanosomes (pigment packets) preserved at a subcellular level, researchers identified patterns, such as the black bandit stripe on Sinosauropteryx. Furthermore, the counter shading found on Psittacosaurus suggests it lived in a forested ecosystem. Defense mechanisms, similar to those seen in modern ecology, were also present. For instance, lace wings (Grammalysa) possessed eye spots on their wings, likely intended to mimic the eyes of a predator, most plausibly a small theropod dinosaur, thus providing a glimpse into Cretaceous signaling and ecology.
The iguanodontians were an incredibly successful group within the Cretaceous. They could reach incredible sizes, with the largest species even matching the proportions of some sauropods, and they also had an incredible palaeogeographic range, meaning that their remains are found all over the world today. In the late Jurassic, they were a lot less diverse and much smaller, so the late Jurassic and early Cretaceous are key times for understanding the evolution of this group. Cariocecus bocagei is a newly described iguanodontian from the Early Cretaceous of Praia do Areia do Mastro, Portugal. Whilst it is only know from a partial skull, there are numerous useful characteristics that help identify it as a new species and fill in our understanding of iguanodontians in this important time in their evolution. Joining us in this episode is Dr Filippo Bertozzo of the Royal Belgian Institute of Natural Sciences.
Dodos are probably the single most famous case of recent human-induced extinction. First documented in the late 1500s and extinct within a century, dodos have become a global reminder of the devastating potential of human activity. This episode, we review the brief history of human interactions with dodos, and we explore what recent research and fossil evidence has taught us about these birds and their closest relatives. In the news: Cretaceous crocs, extra-spiky dinosaurs, turtles of the sea, and cave fish evolution.

Meet the Kaprosuchus, also known as the “Boar Crocodile”! This amazing crocodile-like creature lived during the Late Cretaceous and had giant tusk-like teeth that made it one of the most unusual reptiles of its time. In this episode of the Dinosaur George Kids Podcast, paleontologist educator Dinosaur George explains what made Kaprosuchus so fierce and fascinating.You'll discover:How Kaprosuchus used its long teeth to hunt preyWhere paleontologists have found its fossilsWhy it was nicknamed the “Boar Crocodile”Plus, August Birthday Shout-outs for our T-Rex Patreon Members!
The gang ends “Wet Hot Archosaur Summer” with the final podcast recorded from our undisclosed location in the woods. For this podcast, we indulge Amanda by talking about birds and trace fossils. The first paper looks at the remains of nesting sites that date back to the Cretaceous, and the second paper investigates sources of error in estimates of avian maximum speeds from trace fossils. Meanwhile, Amanda has a message for the bears, James proposes an alliance with the crows, and Curt does an “homage”. Up-Goer Five (Curt Edition): The friends talks about two papers that will make one of them very happy because they are all about the ways that animals that fly can make marks on the ground to let us know about how they move. The first paper looks at where these animals that fly will make their home. This paper shows that animals that fly have been found in this cold place near the top of the world for a really long time. This place would not have been as cold as it is today, but would have been dark for half the year. Some of the animals they find in this area look like they would have moved in when things were good and left when things got bad. This is something we see animals that fly do today in the top of the world as well. The second paper looks at how we try and use how these animals make marks on the ground to see how fast they would move. The paper shows that the way we were doing it in the past kind of worked, but also didn't work. This is because when these animals that can fly move, they do not move in the same way as other animals all the time. And so the way that these things walk is important if we want to try and understand more about how fast they could move from the marks on the ground. References: Wilson, Lauren N., et al.

Ants are a hugely successful family of eusocial insects with over 14,000 modern species described. They are known from every continent except Antarctica and show a wide range of ecologies. Whilst many of us are familiar with their highly organised social structures and castes, there still remain a lot of public misconceptions about how their societies function. The evolutionary history of ants is equally as impressive, with roughly as many fossil ant species known as there are of dinosaurs! Since their appearance in the Cretaceous, several early lineages of ants (stem ants) have gone extinct. In this episode, we're joined by Dr Christine Sosiak of the Okinawa Institute of Science and Technology as we explore what some of these stem ants were like and ask how the different groups of ants fared over geological time.
