Terrible Lizards

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...

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 wh...

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 reco...

The year 2024 is the 200 th 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...

Stegosaurus with Dr Susie Maidment THE TIME HAS COME. For ages Dave, for very Dave reasons refused to cover one dinosaur. Now, we find out all about it with an expert in the field.  Last year's mystery xmas present to all of you who support us now for everyone. Patrons will get an video bonus episode. You can follow Susie Maidment https://twitter.com/Tweetisaurus .

Longtime listeners will be familiar with the fact that Dave has spent a lot of time looking at and working on various bites marks on dinosaur bones left by the carnivorous theropods. These can tell us an enormous amount about who was doing what to whom and what it can mean for the ecology and behaviour of both the herbivores that were bitten and the carnivores that bit them. However, to date work...

Dinosaur documentaries are booming again so it's time to blow the lid on some insider secrets of how these get made. (Alternative description: Dave complains for an hour about being messed around by TV companies and ignored by the very producers and directors who hired him for his advice on the models and scrip they are working on). Dave and Iszi share their stories from behind and in front of the...

Odd ideas in palaeontology Palaeontology as a scientific field is beyond popular in the media and with the public but that also means it draws a lot of attention from those with, let's call them, questionable ideas. And no group gets more of this stuff than the dinosaurs and the animals of the Mesozoic. This time out, Iszi and Dave discuss the world of paleo cranks, people with outlandish and non-...

It is the mega questions episode! Due to Dave etch-a-sketching everything in his life, making things like access to the internet an unusual hurdle, we decided to do answer as many questions we could in an hour. We didn't manage to run out of questions. Big thanks to Trisha, Sophia, Matt, Roy, Harris, Marcus, Noah, Jay, Aurous Azhdarchid, Rachel, Richard and David.   The mystery of allosaurus arms...

Petrodactyle and Pterosaur Growth Dave has had a productive year for pterosaur papers and now two are out in quick succession(!) so get ready for a double-whammy podcast of him rolling his eyes when Iszi mentions flappy-flaps and he's trying to be serious. Anyway, first up is a new large pterosaur from southern Germany with a massive bony crest on its head. The specimen is owned by the Lauer Found...

This week a 'what I did on my holidays' from Dave, though it wasn't a holiday and he dug a hole in Utah and looked at a ton of museums and quarries. The Morrison Formation is a legendary slice of dinosaur history with a huge number of famous sites, important fossils, and features animals like Diplodocus, Allosaurus and Stegosaurus . After far too many years, Dave finally made it out to some of the...

Pterosaurs flew! No big shock there, but obviously flight places major constraints and selective pressures on the skeleton. This should mean all pterosaurs have standard, not-that-varied flight anatomy (in the same way most walking animals have similar leg anatomy).  It turns out an absolutely critical part of the pterosaur is both basically all but unstudied and wildly variable, yes, it's the ste...

Sauropods in general don't get the love they should on Terrible Lizards because, well, Dave doesn't know that much about them (and everyone knows theropods are best anyways). However, there's more than a couple that are both well-known enough in general and Dave know a bit about them that we can talk for a decent amount of time. Step forward the long-neckiest of the long-necked sauropods, Mamenchi...

This is an area we have definitely covered before but it's one of perennial interest and keeps coming round with new studies, how can we tell what ancient animals were doing with weird features. More specifically, how do claims that this feather, or sail, or frill, or claw were used as a display feature stack up? Can we really work out what dinosaurs are doing with features like this and how can w...

Dinosaurs and other prehistoric animals have been a hit in the media for about as long as palaeontologists have been digging them up. But even in the modern age of digital communication, there is almost always an intermediate (and often several) between a palaeontologist and their audience when it comes to communicating about these animals. Whether it's journalists, reporters, documentaries and pr...

We are into series 9 now and still going, though starting with this episode, in a bid to be more consistent and less panicked about completing series and the gaps between, we're moving to being a monthly podcast. So no end in sight yet for all you dinosaur (and sometimes pterosaur) lovers.   Anyway, we're kicking off by talking about arguably the most common way that people encounter dinosaurs and...

The end of the series is our favourite - we answer your questions!  A massive thank you to our patrons who contributed the questions. Go to patreon.com/terriblelizardds for a bonus episode out next week. Do keep in touch #terriblelizards @iszi_lawrence @dave_hone Buy Dave's Book - How fast did T.Rex Run/The future of Dinosaurs. Look out for iszi's childrens books: Blackbeard's Treasure is out in J...

Dinosaur jaws and feeding with Ali Nabavizadeh We started with theropod feeding but what about the herbivores? This week we're joined by Ali Nabavizadeh who specialises in the jaws and teeth of the ornithischian dinosaurs and how these work and how this plays into their feeding ecology. This gives Dave ample opportunity to ask vexing questions about their jaws and elicit the same response he gives...

Although we looked at some biomechanical work earlier this series, this time we get into the real depths of how dinosaurs moved. John Hutchinson joins us with tales of galloping crocodiles and white dots on elephants in an effort to understand how these animals move as part of his work on dinosaur locomotion. We talk about how Jurassic Park cheated to make the T. rex look faster and just how you c...

Some dinosaurs haven't had enough love on here (though some get what they deserve, I mean, who even likes Stegosaurus ?) and chief among them are the sauropodomorphs. However, this week we make a belated and desperate attempt to correct that by talking to Paul Upchurch for an hour. One of the world's leading experts on these herbivorous giants, he takes us through a whole bunch of his research his...

Crystal Palace Dinosaurs with Mark Witton We have covered palaeoart here from time to time and the process of producing images of dinosaurs and other prehistoric life (as both technical illustrations and more creative life reconstructions) but one of the most important of these gets far too little attention. In the 1800s life size replicas of dozens of ancient animals were put up in a park in sout...

British iguanodontids with Joe Bonsor We have touched on Iguanodon before as one of the earliest named dinosaurs and an animal with some interesting relatives and famously spiky thumbs but they never really got the attention that they should have done (from us at least). Enter Joe Bonsor who is finishing off his PhD on these very animals and trying to sort out the utter mess that is the taxonomy o...

Following up on the previous series where pterosaurs dominated, we had to sneak in a bit more of them here. Dave has always had an aversion to the toothy ornithocheirids as while so many of them turn up in 3D (unlike pretty much all other pterosaurs) they also have a horrific taxonomic history and they are a nightmare to deal with. Happily, Taissa Rodrigues is here to talk all about them and she h...

Theropod jaw biomechanics with Manabu Sakamoto We are still going! We are back and like last series, we're taking a bit of a different tack to the previous ones and here we are having experts on every episode in a desperate attempt to make up for Dave's quite profound lack of knowledge in numerous areas of dinosaur biology. With that in mind, we start off with Manabu Sakamoto who works primarily o...

The new series will start on the 12th of October! If you would like to support us and get our bonus episodes sooner - please consider becoming a patron on patreon.com/terriblelizards. Pterosaurs living during the Jurassic period were thought to have been relatively small, but a stunning new skeleton shows otherwise. Natalia Jagielska has helped describe the new find in Scotland which has changed o...
