Classically, it describes the sudden appearance of complex fossils (including all major animal groups) at the beginning of the Cambrian Period. Before then it was thought that only relatively simple single-celled or multicellular life existed. We now understand this event to be a lot more nuanced, recognising… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep177.mp3?dest-id=108425) ## [Episode 176: Insect Gigantism Pt2](https://www.palaeocast.com/insect-gigantism/) _2026-05-13 · Palaeocast_ The Carboniferous period is host to some of the largest arthropods to have ever lived. Giant taxa such as the griffenfly Meganuera and the millipede Arthropleura are almost talismanic and are often depicted in reconstructions of the period. Since many other groups also have giant representatives in the Carboniferous, what is it about this time that allows for arthropods to grow to such large… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep176v2.mp3?dest-id=108425) ## [Episode 175: Insect Gigantism Pt1](https://www.palaeocast.com/insect-gigantism/) _2026-05-02 · Palaeocast_ The Carboniferous period is host to some of the largest arthropods to have ever lived.

We took this as an opportunity to get an overview of what we really know about dinosaurs and how it's even possible to tell their story with just 50 specimens. In this episode, Paul discusses the history of dinosaur research, the current state of the science and what are still some of… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep174.mp3?dest-id=108425) ## [Episode 173: Petrified Forest](https://www.palaeocast.com/petrified-forest/) _2026-03-17 · Palaeocast_ Petrified Forest National Park in northeastern Arizona, USA is a hub for Triassic palaeontology and has exposures representing 20 million years of the Late Triassic Chinle Formation. Visitors marvel at the colourful fossilised trees from which the park takes its name, but a whole host of animals called these swampy forests home 225 million years ago. In this episode, we talk to Dr. Adam Marsh,… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep173.mp3?dest-id=108425) ## [Episode 172: Rhynchocephalians](https://www.palaeocast.com/rhynchocephalians/) _2026-02-05 · Palaeocast_ Today, there is only one living species of rhynchocephalian: the tuatara of Aotearoa/New Zealand. Despite today's paucity of species, this was once a diverse group of reptiles, with a wide range of lifestyles from swimming in the ocean to climbing trees. Once highly abundant around the world, reasons for their decline are still debated and may have had to do with competition from their relatives,… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep172.mp3?dest-id=108425) ## [Episode 171: Freshwater Mosasaurs](https://www.palaeocast.com/mosasaurs/) _2025-12-12 · Palaeocast_ We've been given exclusive access to a brand new study examining the chemistry of a mosasaur tooth found within the Late Cretaceous Hell Creek Formation, North Dakota. The remarkable circumstances of how this tooth was discovered meant that multiple lines of chemical evidence could be reliably gathered, each acting as a powerful palaeoenvironmental proxy providing clues as to how and where this… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep171.mp3?dest-id=108425) ## [SVP 2025](https://www.palaeocast.com/svp-2025/) _2025-12-03 · Palaeocast_ [Listen](https://traffic.libsyn.com/secure/palaeocast/SVP2025.mp3?dest-id=108425) ## [Episode 170: Cariocecus bocagei](https://www.palaeocast.com/cariocecus-bocagei/) _2025-09-19 · Palaeocast_ 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… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep170.mp3?dest-id=108425) ## [PixelRift — Platforming with Level Editor (Sponsored)](https://crawlproof.com/a/BttBTBuiYGlz) _2025-09-19 · **Sponsored**_ Includes a built-in level editor, campaign with elemental heroes, and boss encounters. ## [Episode 169: Grasslands Pt2](https://www.palaeocast.com/grasslands/) _2025-09-13 · Palaeocast_ Grassy biomes, including grasslands, savannahs and crops, cover over 40% of all land on Earth. They play a significant role in carbon and silica cycles and have a large impact upon the climate. Grasslands (grass-dominated ecosystems) have shaped the evolution of numerous groups of organisms, most obviously grazing mammals, and can support a huge amount of biodiversity. Humans evolved in the… [Listen](https://traffic.libsyn.com/secure/palaeocast/Ep169.mp3?dest-id=108425)
