Travis and Alyssa discuss the challenges and implications of open access publishing in science. They explore the paywall paradox, the role of jargon in scientific communication, and the peer review process, particularly in the context of palaeontology. The conversation also touches on global inequities in access to research, innovations in open access publishing, and the importance of data accessibility. The episode concludes with a light-hearted segment on the frustrations of academic publishing and a fun bingo game.

Alyssa and Travis delve into a fascinating new paper on dinosaur tracks, dubbed the 'Dinosaur Dance Floor.' They discuss the implications of the findings, including the behavior of ceratopsians and tyrannosaurs. The conversation shifts to exciting announcements in paleontology, including a new season of Prehistoric Planet. They also interview shark palaeontologist Ben Francischelli, exploring the megalodon and other ancient sharks. The episode concludes with a fun 'Would You Rather' segment.

Poo and poetry.

George Frandsen is founder of the Poozeum in Williams, Arizona. He shares the story of the Poozeum and its mission to educate the world about coprolites. George also introduces us to Barnum - the world's biggest T. rex poop. Alyssa and Travis review Walking with Dinosaurs and Jurassic World: Rebirth before Travis unleashes his softer side with a little palaeo poetry ('Species' by Tishani Doshi, from A God at the Door published by Cooper Canyon Press).

From Part 2 of our interview with palaeontologist and palaeoartist Mark Witton featuring chat on AI, to news about the origins of teeth, and a very difficult game of 'guess that fossil', this episode has a little bit of everything.

Can they spell it? No, they can't!

This episode features renowned palaeoartist Mark Witton talking about his new book King Tyrant and other topics in palaeoart. Plus, news on the world's first sauropod gut contents. Then, Travis and Alyssa challenge each other to a prehistoric spelling bee.

Palaeo artist James Pascoe shares his lifelong fascination with dinosaurs and how it has shaped his journey. He discusses the importance of community in the paleo art world and the role of engagement in science communication.

We discuss new research showing the origin of tyrannosaurs may have been in Asia and also how megaraptors arose and spread throughout Gondwana. And another new paper pushes back the origin of tetrapods and (maybe) places it in the southern continents.
