Dinosaur mating? Two new tyrannosaurs? We discuss a couple of groundbreaking papers followed by a trip to Wellington Caves, the site of some of Australia's earliest and greatest palaeontological discoveries.

Seals. What do they know? Do they know things? Let's find out.

Dr James Rule gives lets us in on the secrets of the seals, covering their evolution, fossil history, and some challenges with modern marine mammal research. James tells us the best and worst seal and lays down the terms to the whales. Also, it's Halloween, so we take a look at some creepy museum exhibitions.

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.

Virtual Paleo Art Gallery curator Karim talks the intersection of art, technology, and community building. Meanwhile, Alyssa and Travis discuss some historical paleo and museum heists.

Artist, cartoonist, communicator Zev Landes talks through his experiences and process. We get the low-down on how he created the Fossils and Fiction logo featuring Scratch and Skitters, as well as his work with museums, palaeo-tourism initiatives, and much more.

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.
