The gang discusses two papers that study the paleoecology of the Ediacaran fauna. The first paper looks at environmental information that can be gleaned from the microbial mats these organisms lived on, and the second paper studies how different Ediacaran fossils are distributed on this microbial mat. Meanwhile, James is having a week, Curt is unsure about chips, and Amanda is comfortable being very on brand.   Up-Goer Five (Curt Edition): The friends look at two papers that study some very old animals that lived a long long time ago and lived on these beds of tiny tiny tiny animals and not animals. In fact, these two papers are also interested in the beds these things lived on and how they lived on the bed. The first paper looks at these parts of the beds and how you can find them in different beds made of tiny tiny tiny animals and not animals. There are these lines in the beds that are found in some beds but not all of the beds. They think that the way water moves over the beds may cause these lines to form. The other cool thing they find is that the animals are found when there are these lines, and are not found when there are not these lines. This means that the way the water moves might be important for these animals to live. The second paper looks at how these animals lived in space with each other. Did they want to live close to each other or did they want to be far from each other, or do they not really care? Some earlier papers had said they wanted to be far from each other, which is weird when we look at animals in the big blue wet thing today which want to stay close to each other. So they run a lot of studies on three different animals that can show if they are close to each other because they all need the same thing (and that thing is in small parts around the ground) or if they seem to want to be very close to each other because they either use each other or they can not move far from each other. They show that these animals all show that they are close to each other, but two of the animals are close because they all want something that is in just a few places. One animal shows a really strong need to be close, which could mean that this is something about the animal that makes new babies be closer to the father/mother. This shows we can learn things about how these animals lived and why they lived where they did, even for things that are very very very old.   References: Boan, Phillip C., et al.

Todos sabemos que el clima de nuestro planeta ha ido cambiando a lo largo de los millones de años de vida de la Tierra, y a veces esos cambios han sido drásticos. Hoy visitamos un episodio crítico en la historia de nuestro planeta, justo anterior a la eclosión de la vida tal y como la conocemos: el periodo Criogénico, hace unos 650 millones de años. En esta época la temperatura de la Tierra se desplomó y los hielos cubrieron no sólo los polos, como los conocemos ahora, sino la mayor parte del planeta. A este estado lo solemos llamar "Tierra Bola de Nieve", y siempre ha habido dudas sobre cómo sobrevivió la vida a este episodio tan intensamente frío. A lo largo de los últimos años se han ido acumulando evidencias de que aunque casi toda la superficie de la Tierra estuviera congelada, en el ecuador y los trópicos sobrevivieron algunos refugios donde los seres vivos se parapetaron durante esta glaciación que, con varios episodios, duró más de 50 millones de años. Para hablaros de todo ello contamos con la ayuda de Nahúm Méndez Chazarra, geólogo, divulgador científico y autor de varios libros, como "Un geólogo en apuros" o "Todo lo que hay que saber sobre geología".

Las primeras etapas de la evolución de la vida son sumamente oscuras: sabemos poco sobre el origen de grandes grupos como las algas, los hongos y los animales (de las plantas sabemos un poco más porque fueron las últimas en aparecer, cuando un alga dio el salto a la tierra firme). El caso de los animales es especialmente enigmático, porque de su origen tenemos dos fotografías: una que reconocemos bien y otra que no terminamos de entender. La mayoría de los grupos de animales que conocemos estaban ya presentes en el periodo Cámbrico, hace unos 540 millones de años; eran más primitivos que sus formas modernas, pero ésa es la foto que reconocemos. Después tenemos *la otra foto*: sólo un poco antes, hace 600 millones de años, los fósiles nos muestran un mundo de seres con forma de esterilla, de pluma o de bolsa; no se parecen especialmente a los animales modernos, pero... deben de ser sus antepasados, ¿no? Son los seres de Ediacara, un conjunto de organismos blandos y difíciles de identificar que precedieron a los animales tal y como los conocemos y que desaparecieron rápidamente tras la irrupción de la fauna del Cámbrico. Hoy los vamos a conocer un poco mejor: el siglo XXI está retirando el velo que nos impedía ver con claridad a los seres de Ediacara y empezamos a reconocer que algunos eran realmente antepasados de los animales. En un artículo publicado hace unas semanas una nueva técnica de análisis químico arroja un poco de luz sobre un aspecto fundamental de su biología: la alimentación. Si os interesan estas etapas de evolución temprana de los seres vivos repasad (por orden de aparición evolutiva) los capítulos s10e28, s06e32, s10e38, s05e33 y s05e38, que complementan al que os presentamos hoy :) Este programa se emitió originalmente el 3 de enero de 2023.

In 1946, sharp-eyed geologist Reg Sprigg noticed some strange patterns in the rocks of the Flinders Ranges. What he had discovered was a groundbreaking a fossil record of complex creatures dating back 550 million years. The Ediacara fossils were – and remain – the earliest record of complex multi-cellular animals on the planet. While the site is world famous with scientists, many South Australians are unaware of its existence, despite a campaign to have Flinders Ranges world heritage-listed. That could be about to change, with materials about the fossils and their significance being introduced to the Year 8 curriculum for the first time next year. And now – for anyone who is interested – you can do a virtual dive into those shallow, warm ancient sees to swim with the Eediacaran creatures. On the podcast this week, David Washington is joined by InDaily senior journalist Belinda Willis, and  University of South Australia geology professor Tom Raimondo who has led the project to bring these fossils to virtual life.

I'm your host, Kate Shaw. It's the last week of August 2022, so let's close out invertebrate August with a whole slew of mystery fossils, all invertebrates. But first, we have a birthday shoutout! A humongous happy birthday to Isaac! Whatever your favorite thing is, I hope it happens on your birthday, unless your favorite thing is a kaiju attack. We've talked about the Cambrian explosion before, especially in episode 69 about some of the Burgess shale animals. “Cambrian explosion” is the term for a time starting around 540 million years ago, when diverse and often bizarre-looking animals suddenly appear in the fossil record. But we haven't talked much about what lived before the Cambrian explosion, so let's talk specifically about the Ediacaran (eedee-ACK-eron) biota! I was halfway through researching this episode when I remembered I'd done a Patreon episode about it in 2021. Patrons may recognize that I used part of the Patreon episode in this one. You'd think that would save me time but surprise, it did not. The word Ediacara comes from a range of hills in South Australia, where in 1946 a geologist noticed what he thought were fossilized impressions of jellyfish in the rocks. At the time the rocks were dated to the early Cambrian period, and this was long before the Cambrian explosion was recognized as a thing at all, much less such an important thing. But since then, geologists and paleontologists have reevaluated the hills and determined that they're much older than the Cambrian, dating to between 635 to 539 million years ago. That's as much as 100 million years before the Cambrian. The Ediacaran period was formally designated in 2004 to mark this entire period of time, although fossils of Ediacaran animals generally start appearing about 580 million years ago. Here's something interesting, by the way. During the Ediacaran period, every day was only 22 hours long instead of 24, and there were about 400 days in a year instead of 365. The moon was closer to the earth too. And life on earth was still sorting out the details. Fossils from the Ediacaran period have been discovered in other places besides Australia, including Namibia in southern Africa, Newfoundland in eastern Canada, England, northwestern Russia, and southern China. Once the first well-preserved fossils started being found, in Newfoundland in 1967, paleontologists started to really take notice, because they turned out to be extremely weird. The fossils, not the paleontologists. Many organisms that lived during this time lived on, in, or under microbial mats on the sea floor or at the bottoms of rivers. Microbial mats are colonies of microorganisms like bacteria that grow on surfaces that are either submerged or just tend to stay damp. Microbial mats are still around today, usually growing in extreme environments like hot springs and hypersaline lakes. But 580 million years ago, they were everywhere. One problem with the Ediacaran biota, and I should explain that biota just means all the animals and plants that live in a particular place, is that it's not always clear if a fossil is actually an animal.

Zapraszamy na wykład dr Daniela Tyborowskiego - drugi z serii wykładów o stanowiskach paleontologicznych z różnych krajów i części świata. Spotkanie w ramach środowych Spotkań z Dziejami Ziemi, 11 maja 2022 r. Tym razem dr Tyborowski, w ramach nowego cyklu o stanowiskach paleontologicznych i historii naturalnej wybranych krajów i regionów świata, zabrał nas do Australii - jednego z bardziej kojarzących się geologicznie czy paleontologicznie krajów i regionów na naszej planecie. Australia jest bardzo dużym obszarem - cały kontynent, w dużej mierze odsłonięty z geologicznego punktu widzenia - nie ma tam aż tak zwartej pokrywy roślinnej, nie ma aż tylu lasów, spora część kraju to są równiny, tereny pustynne i półpustynne, więc liczba wychodni skał starszego podłoża jest tam znaczna. Nie było w Australii zlodowaceń czwartorzędowych, więc skały starsze niż 2 miliony lat występują naturalnie na powierzchni. Dzięki temu stanowisk paleontologicznych jest tam bardzo bardzo dużo. Wykładowca na potrzebę spotkania wybrał kilka najciekawszych stanowisk i kilka odkryć stosunkowo świeżych i zróżnicowanych. Jednym z najbardziej ikonicznych stanowisk paleontologicznych w Australii (a nawet na świecie) są słynne Wzgórza Ediacara. Stanowiska Ediacara Hills pokazują obraz świata przed kambrem, kiedy organizmy nie posiadały twardych mineralnych szkieletów (ani wewnętrznych ani zewnętrznych) i dna mórz były przykryte matami mikrobialnymi, a na tych matach sobie żyły miękkociałe organizmy (wendobionty). Faunie ediakarskiej dr Daniel Tyborowski poświęcił jakiś czas temu cały wykład. Polecamy: "Fauna ediakarska – enigmatyczni mieszkańcy prekambru" (https://www.youtube.com/watch?v=aS1ZgIcf3GE) Drugie omawiane podczas wykładu stanowisko to Formacja Gogo (pólnocno-zachodnia część Australii, region Kimberley) datowana na dewon. Skały powstające w środowisku rafowym, w czasie gdy północno-zachodnia Australia była brzegiem superkontynentu Gondwana. Ekosystemy rafowe są niesłychanie bioróżnorodne, życie tam tętni. Łatwo więc znaleźć doskonale zachowane skamieniałości dewońskich ryb i nie tylko. Z ery mezozoicznej (okresu jurajskiego) w Australii wschodniej (stan Nowa Południowa Walia, region Sydney) mamy stanowisko Talbragar. Pośród pustkowia znajdujemy odsłonięcia i unikatowo zachowane skamieniałości z końca okresu jurajskiego, mające 100-120 milionów lat. Są to osady kopalnego jeziora, które tu pod koniec jury występowało. Znajdujemy tu głównie ryby - ryby kostnoszkieletowe, promieniopłetwe - ryby doskonałokostne, ale i np. chrząszcze czy rośliny co do jeziora wpadły. Ostatnie odwiedzone podczas wykładu stanowisko to era kenozoiczna, okres neogen, epoka mioceńska - stan Nowa Południowa Walia, region Sydney. Stanowisko pośrodku suchej otwartej Australijskiej równiny kryje odsłonięcia mioceńskie z pięknie zachowanymi skamieniałościami roślin, które występują w strefie tropikalnej - kwiaty, liście. Do tego skamieniałości stawonogów zamieszkujących mioceński las tropikalny - owady, pająki, ptasie pióra. dr Daniel Tyborowski - paleobiolog, uczestnik i organizator badań wykopaliskowych, poza badaniami naukowymi zajmuje się popularyzowaniem wiedzy o faunie prehistorycznej oraz naukach geologicznych Znajdź nas: https://www.facebook.com/WszechnicaFWW1/ https://anchor.fm/wszechnicaorgpl---historia https://anchor.fm/wszechnica-fww-nauka wszechnica.org.pl

Today, we're going to be discussing the Ediacaran fauna. This is a faunal assemblage that came before the Cambrian Explosion (535-525 Mya) but is less well known. Unlike the Cambrian Explosion- which saw the creation of most of the phyla we know today- the Ediacaran biota is much less familiar. It also appears to be quite confusing in terms of what category its constituent organisms fall under... Sources for this episode: 1) Campbell, N. A., Urry, L. A., Cain, M. L., Wasserman, S.

The gang discusses two papers that deal with the events that led to the extinction of the early metazoan Ediacaran fauna, as well as the extinction's philosophical ramifications for our understanding of evolution in general. Chaos runs rampant throughout this podcast as our figurative and literal systems break down through time. But somehow, life.... finds a way.... through a 4G network. Meanwhile, Amanda jumps the gun, Curt makes jokes no one can understand, James "wins" again, and everyone slowly succumbs to chaos and madness. If you're just joining us for the first time, I'm so very... very sorry.    References: Darroch, Simon AF, et al. "Biotic replacement and mass extinction of the Ediacara biota." Proc. R. Soc. B.

Melvyn Bragg and guests Martin Brasier, Richard Corfield and Rachel Wood discuss the Ediacara Biota, the Precambrian life forms which vanished 542 million years ago, and whose discovery proved Darwin right in a way he never imagined. Darwin was convinced that there must have been life before the Cambrian era, but he didn't think it was possible for fossils like the Ediacara to have been preserved. These sea-bed organisms were first unearthed in the 19th century, but were only recognised as Precambrian in the mid-20th century. This was an astonishing discovery. Ever since, scientists have been working to determine its significance. Were the Ediacara the earliest forms of animal life? Or were they a Darwinian dead end? Either way, it is argued, they reveal some of the secrets of the workings of evolution. Richard Corfield is Senior Lecturer in Earth Sciences at the Open University; Martin Brasier is Professor of Palaeobiology at the University of Oxford; Rachel Wood is Lecturer in Carbonate Geoscience at the University of Edinburgh.
