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 is still unanswered. It is sad.  Do check out Dave’s blog and books:...

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 Foundation and Dave talks about them and their work with palaeontologists to bring some new fossils...

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 best known and most important sites and in this episode reports back to Iszi on what he saw and...

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 sternum. Dr Dave Hone (hello!) has just published a huge paper cataloguing and describing basically...

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, Mamenchisaurus. This odd (even by sauropod standards) animal is found in a number of different sites from...

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 we test such ideas with such limited data when they’ve been gone for 65 million years? Well...

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 print, radio or TV, what you say, suggest, demand, advise or write as a palaeontologist often goes...

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 that’s museum displays and exhibits. Dave and Iszi talk through how these things get set up, the...

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 January with Bloomsbury. RAWR!

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 whenever asked about T. rex being a scavenger, but it does mean that Ali talks about how the...

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 can build a model of such huge animals from their bones and how reliable such an exercise really...

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 history from obscure British sauropods to the long necked mamenchisaurs and other oddities. We also...

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 south London and are still there today. Palaeontologist and palaeoartist Mark Witton joins us to...

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 of the iguanodontians in the UK. We dive into this with some surprising conclusions and...

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 has done more than anyone else to sort out these species and their relationships in recent years...

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 on the biomechanics of theropods jaws – what they could and couldn’t bite and how hard and what...

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 our understanding of Flappy Flaps.  Natalia Jagielska is a PhD in Palaeontology at University of...

If you could give the paleontology field NASA's budget what would you do with it? Ever used laser-stimulated fluorescence? How do pterosaurs sleep? Was was Irritator challengeri? When did birds wiggle their hips? How can you tell if species shared an environment? Is there any evidence for intra-specific fighting amongst Pterosaurs? PLUS MORE! We've gotten a plethora of questions this series - Dr David Hone tries to get through them all - with a little help from Iszi Lawrence. Thank you to...

How science works In another in the increasingly long line of topics we probably should have covered quite a few series ago, this week we are addressing some of the fundamentals of what science actually IS. How does it all work really, and what is the difference between a hypothesis and a theory, and how confident can we be about dinosaur research when so much is unknown and difficult to put to the test? All this and some other bits (that I can’t really remember because we recorded this 2...

This is perhaps the question that gets asked the most and so it’s time to address it properly (well, we are 7 seasons in, we were going to get to it sooner or later). So this week we are talking about routes into palaeontology and all that involves, from ‘classic’ academic roles as a researcher at a university or museum, though to science writers, fossil preparators, illustrators and photographers and all manner of other palaeontologically related jobs and careers. As well as all that, we’ll...

Perhaps the best known, and most often misrepresented, pterosaur is Pteranodon. It has become the archetypal pterosaur and is always in the background of every Mesozoic scene (especially with T. rex) to let you know that the pterosaurs are out there. But aside from being quite big and having a funky headcrest (like all the best pterosaurs do) it’s an animal that is constantly overlooked even though we have more than a thousand specimens of it to work from. That’s an odd combination so it’s...

From the very biggest to the smallest, anurognathids were the little fuzz balls of pterosaurs that barely reached 1m wingspan as adults. They were bat-like hawkers, catching insects on the wing with their giant gapes and tiny teeth. Although rare, like the azhdarchids we have recently had a flurry of finds and accompanying research on them which means that they have gone from one of the least to one of the best understood pterosaurs in short order. Better yet, they include several specimens...

If most people know one thing about pterosaurs (well one correct thing rather than them being flying dinosaurs or bird ancestors) it’s that they got really big. At the top end they hit over 10 m in wingspan and probably over 250 kg, massively bigger than the largest flying birds (living or extinct). And all the real giants belonged to one group – the azhdarchids. These long-necked monsters were a real mystery for decades but a flurry of discoveries and research in recent years means we now...

It’s hopefully not a surprise at this point that pterosaurs were fully powered and capable fliers and that they were not passive gliders or could only get airbourne through jumping off of cliffs. While we do talk about flight here, it’s not like that is all pterosaurs could do so we cover their abilities on the ground (and in trees) and take-off, and then whether or not they could dive, swim and how they floated in the water. It’s a whole cornucopia of pterosaur locomotion through three...
