We’ve made plenty of jokes over the years about the general lack of sauropod skulls and the frustrations of trying to work out what these animals were doing when it came to things like feeding when the most important bit is missing. Happily, this week we are joined by David Button who has done a ton of work in this area and is happy to chat to Dave and Iszi about how their heads and teeth were built and what this can (and can’t) tell us about their diets and habits. While we have him trapped, we also quiz him on his recent work on the behaviour of the thescelosaurs, an odd branch of dinosaurs we’ve taken till series 10 to even mention!   Links: Extra content on patreon: www.patreon.com/terriblelizards And old post of Dave’s on the sauropod skeletons in Berlin, that really show off the issue of different feeding heights in these animals: https://archosaurmusings.wordpress.com/2013/01/27/berlin-sauropods/ David’s webpage at the University of Bristol: https://research-information.bris.ac.uk/en/persons/david-j-button

The spinosaurs get all the love (OK, mostly hate) and attention when it comes to the megalosauroids, but they are but one weird branch of this group of theropods. Sadly they have a similar problem to the spinosaurs in that there are annoyingly few fossils of them, and there’s very few people working on these animals. Happily, today Iszi and Dave are joined by one of them, Cass Morrison who is doing his PhD on these unusual animals and is here to give us the lowdown on their evolution, diversity, biogeography and ecology and generally fill us in on these much under-appreciated animals.   Links: For extra content go to our Patreon https://www.patreon.com/terriblelizards   Apiece with Cass about his work on dinosaur brains: https://www.nhm.ac.uk/discover/behind-the-science-cassius-morrison.html   Find Cass on Twitter https://x.com/casscretaceous and Instagram https://www.instagram.com/cretaceous.cass/?hl=en-gb

We have touched on the extinction that killed the dinosaurs plenty of times before over the various seasons of TL, but we have never really tackled it fully before. Finally, we are joined by a real expert on this subject, Melanie During who is in the process of finishing her PhD on this very subject. So prepare for not actually really any dinosaurs, but quite a lot of geology and geochemistry to learn how the impact was so utterly devastating and how we know. It turns out that they never stood a chance and that the damage was even worse than even Dave had realised.   Links: support us on patreon and access extra content:  www.patreon.com/terriblelizards   A link to Melanie’s YouTube series which is on long term hiatus but full of cool videos to watch (even if it notably fails to include a certain silver-haired pterosaur and tyrannosaur researcher): https://www.youtube.com/c/GenuineRockstars/videos   Here’s a link to Melanie’s press stuff for her papers but it includes some videos and graphs of that we talk about https://uppsala.app.box.com/s/ikmlwtb0vui7zn5k74jfokbhysla8ck1

Live edited recording at The Oxford Fire Station on 25/05/2024. Live Anniversary Q&A for the Oxford Podcast Festival It’s the 4th (!) anniversary of the launch of Terrible Lizards and this came at a perfect time as Iszi and Dave got invited to do the recent podcast festival in Oxford. So, while we have our usual end of series Q&QA episode in a few months, here we have an early one with questions from out live audience. We thought that was more appropriate then for us to just rabbit on (or dinosaur on) in front of people and it made for a pretty compelling exchange, the time simply flew by. An obviously thanks to the organisers for hosting us and especially to all the people who actually trekked there (from Edinburgh! From Germany!) and then spent actual time to just listen to us. It’s still all rather confusing and unsettling, but they say it takes all sorts to make a world. Anyway, here it all and happy birthday to us, and thanks for listening.   Links: Podcast festival link: https://www.saintaudiopodcastfestival.com/ Support us on Patreon for extra content: https://www.patreon.com/terriblelizards

We all know about how common dinosaurs can be in places like Europe, Argentina, the US, China and Mongolia, but they have turned up in dozens and dozens of countries and on every continent, including Antarctica. Unsurprisingly, it’s a very tough place to work, it costs a ton of money, and there are not that many dinosaurs to be found, but they are there. Today we are joined by Matt Lamanna of the Carnegie Museum who has spent multiple field seasons on the chilly continent and he tells us about lush forests, tiny dinosaurs, ancient birds and modern penguins. So join us to learn about what is perhaps the last great unexplored area of dinosaurs, the bottom of the world.   Links: SEE TERRIBLE LIZARDS LIVE! https://oldfirestation.org.uk/whats-on/terrible-lizards-podcast/   Matt’s website on the project: https://antarcticdinos.org/   Matt’s profile at the Carnegie: https://carnegiemnh.org/research/matthew-lamanna/   A short post of Dave’s on the Carnegie sauropods, click through the next few posts if you want to see all of their dinosaurs: https://archosaurmusings.wordpress.com/2011/11/10/cargenie-dinosaurs/

Dinosaur footprints with Peter Falkingham Footprints and trackways are an amazing source of data on how dinosaurs moved and what they did. But interpreting these can be a real nightmare since it’s hard to work out the interactions between a moving foot and the actual surface, or work out which species might have made which tracks. At the forefront of solving some of these issues and working out what we can and can’t meaningfully day about dinosaur tracks is Professor Peter Falkingham at Liverpool John Moores University. So today he joins us to talk about chasing birds across mud, literal books made of fossil dinosaur footprints and using X-rays to work out how dinosaurs moved. There’s so much in here and you’ll never walk across a beach again without looking back at your own tracks.

We don’t often delve into the Triassic since Dave is not well versed in that time and the animals that were around then, but there were some very important animals that we’ve unduly overlooked across the last 9 series. Happily, today we can redress a large part of that with this episode on Coelophysis. Known from hundreds of skeletons, it’s one of the best represented dinosaurs in the fossil record and yet it remains criminally understudied despite the available data. As one of the earliest theropods, it is perhaps archetypal of the lineages came later, but as so often happens, a bunch of questionable taxonomic decisions and referrals over the decades has left the animal in a bit of a mess. Here to help clear that up is Skye McDavid, scientific illustrator and independent researcher who has put far more time into sorting out the problems of Coelophysis than most would deem wise and joins us to share her wealth of knowledge.   Links: Skye’s hub on her website with links to her art, socials etc. https://www.skyemcdavid.com/links Please support us on patreon and unlock extra content! https://www.patreon.com/terriblelizards

The year 2024 is the 200th anniversary of the naming of the first dinosaur, Megalosaurus. While ‘Dinosauria’ wouldn’t be coined till 1842 (so we have a fair wait before that anniversary kicks in, and doubtless will be marked with another major celebration) it is a great time to take stock of where we are in dinosaur palaeontology. So obviously a good idea is this, that the Natural History Museum in London organised a major international meeting for this, and Dave went along. So in this episode of our (yes, really) 12th series, Dave reports back to Iszi on what was going down at the conference and looks back on 200 years of dinosaur-ing and forwards to what’s coming soon of the back of the meeting.
