Fossils and Fiction

A supermarket tabloid once ran a front page reading "Space Probe Finds Dinosaurs on Mars." That issue ended up pinned to the wall of the Montana dig trailer in Jurassic Park — and it's the starting point for a wander through everything that connects palaeontology and space. Travis and Alyssa cover the 1992 Weekly World News hoax and how it accidentally recreated the founding error of dinosaur science, the supernovae that may have triggered two mass extinctions, the asteroid ejecta you can touch in the Flinders Ranges, the hypothesis that Earth had rings while trilobites were alive, dinosaurs living on the far side of the galaxy, and NASA's carefully-worded potential biosignature on Mars. Plus: 65 , Strange New Worlds , Love, Death & Robots , and why every screen dinosaur still says 65 million years when the answer changed in 2012. Recorded on the 60th anniversary of Star Trek .

A three-course food web from the Cretaceous seas of Queensland: a Platypterygius australis ichthyosaur that had been snacking on fish, cephalopods and pterosaurs — before it, in turn, got chewed on by a Kronosaurus queenslandicus . Travis and Alyssa dig into what the bite marks and gut contents tell us about who was eating whom in ancient inland Australia. Then, Travis heads out to Gold Creek to sit down with Shannon Bourke, education and outreach coordinator at the National Dinosaur Museum in Canberra, for a tour through animatronic accuracy (and inaccuracy), seasonally repainted triceratops, and how a small private museum can uietly launch palaeontology careers. To close out: a preview of The End of Oak Street — dinosaurs, suburbia, Ewan McGregor punching things — and the story of the one Chase question Travis really should have known.

Dr Jake Kotevski didn't become a palaeontologist because of a fossil. He became one because of Sam Neill. In this tribute episode, Travis and Alyssa talk with Jake about Alan Grant's quiet, unglamorous masculinity, the "sense of wonder" the movie chose over the book's horror, and why Grant's evolution across three films (and an unfortunate franchise reboot) still resonates thirty years on.

Compsognathus in a handbag. Microraptor as a pet crow. Sauropod methane energy. You're welcome. We sit down with Professor Amy Brock-Hon from the University of Tennessee at Chattanooga — Alyssa's old alma mater — to talk caves, karst, and why a good geology degree might be the most versatile qualification you've never considered. Then we dig into a 2025 paper claiming scientists have found original collagen inside a 66-million-year-old Edmontosaurus hip bone — and ask what that means for the long-running soft tissue debate. Which leads us, naturally, to de-extinction — what we'd bring back, why, and whether Colossal Biosciences hatching chickens from synthetic eggs means we're closer to an answer than we'd like to admit.

The ocean had apex predators long before sharks — and this week, we're diving into the extraordinary world of ichthyosaurs with one of the world's leading experts on them. Alyssa sat down with Dr Dean Lomax — palaeontologist, author, broadcaster, and all-round ichthyosaur evangelist — ahead of his first-ever visit to Australia for Queensland Dinosaur Week (4–10 May 2026) . It's a conversation about science, storytelling, and what it really takes to build a career in palaeontology when nobody in your family has ever been to university. Plus: Travis is flying up to Brisbane for Dino Week himself, we make some big announcements about the future of the show, and we reveal what kookaburras have in common with Jurassic Park. -- Dr Dean Lomax's website: deanrlomax.co.uk Locked in Time — Dean Lomax and Bob Nicholls The Secret Lives of Dinosaurs — Dean Lomax and Bob Nicholls Why Dinosaurs documentary — [available free on YouTube] Queensland Dinosaur Week Fossils and Fiction membership and merch Fossils and Fiction is kept ad-free by our members.

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. __ Flynn, A. G., Brusatte, S.

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. More info: Bell, P.

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 Dinosaur s 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).

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. __ Long, J. A., Niedźwiedzki, G., Garvey, J., Clement, A. M., Camens, A. B., Eury, C.

This conversation explores the fascinating and often humorous world of paleontology hoaxes, from the infamous Piltdown Man to the Cardiff Giant. Alyssa and Travis discuss various historical and modern examples of scientific fraud, the implications of these hoaxes on the scientific community, and the lessons learned about integrity in research. They also touch on the cultural significance of these hoaxes and how they reflect societal beliefs and values. __ Palaeo Pulse: McCurry, M. R., Gill, A. C., Baranov, V., Hart, L.
