Terrible Lizards

The Future of Dinosaurs No guest this week as Dave manages to ramble on for an entire hour on his own again (well, Ok, Iszi helps him ramble). To be fair, he's got a new book out and since its 80 000 words of dinosaur ideas we thought we should cover it and it was never easily going to fit into 40 minutes. What's this amazing [citation needed] new book on? Well it's all about what we don't know ab...

Alvarezsaurs From a micro dinosaur to the very smallest, this time out we're looking at the little alvarezsaurs which include the smallest of the non-avian dinosaurs and with several species that were the tiniest yet found in the Mesozoic. Dr Steve Cross joins us to analyse a popular work of dinosaur fiction. Dr Steve Cross is a an incredible consultant and STEM communicator. Find him, follow him,...

Evolution In one way it's more than a bit late to only talk about evolution when we are 6 and a bit series into Terrible Lizards and this should arguably have been episode 1 in series 1 but here we are. Evolution is the foundation for modern biology and the understanding that species and lineages change over time and also how that happens allows us to interpret those changes patterns. While we bar...

We've already mentioned Gigantoraptor this series so let's get down to the other end of the etymological scale and look at Microraptor . This little dromaeosaur was one of the first fully feathered dinosaurs to be found and is famous for its 'four wings' with long flight feathers on the legs and the arms. There's loads of good specimens of this animal so it is perhaps no surprise that there has be...

At various times in previous episodes we have talked about what various dinosaurs ate and bits of data about diet, but this time we're going to take a more systematic look at how palaeontologists work out the diet of ancient animals. We go through the obvious ones like sharp teeth and finding bits of stuff inside them to microscopic traces of damage on the enamel, the structure of teeth and elemen...

Back to dinosaurs so you can relax (though the pterosaurs will return next series). This time out, we are going with the oviraptorosaurs - and note the long name, it's not just oviraptors we are covering. As is common, the one famous member of this group tends to hog the limelight and not everyone knows about the others even if these days Gigantoraptor tends to sneak in in the background. These fe...

Series 6? That can't be right. Surely this is 3 or 4 or something, 5 at the outside. Blimey. Anyway, we are back and we have new episodes though we are cheating already by starting with a pterosaur and talking about the greatly underappreciated Rhamphorhynchus . As the only vaguely well-known long-tailed pterosaur it is shown in the background of every Jurassic dinosaur painting to give scale the...

A slightly silly intro to series 6 of Terrible Lizards, a podcast about dinosaurs which will be starting on Wednesday 9th of February 2022. (The guest on this clip is Dr Steve Cross).

We talk to Yara Haridy who has just completed her PhD on the histology of dinosaurs and other reptiles. On the podcast we normally just talk about whole bones and skeletons (or at least the bits of them that are preserved) but there is an enormous amount of information that is preserved in the fossilised cellular structures of these. Fossil bones are those that have turned to rock but that means t...

Are there dinosaurs on the moon? What are digs in Antarctica like? Dave Hone and iszi Lawrence answer your dinosaur Questions! At the end of each series Iszi and Dave trawl through all the comments and messages from our listeners. We answer questions from Elaine, Michelle, Lee, Hunter, Sabina, Phil, David,  Leo & Quantum Robin (Kristjan), Russell, Shuyi, Steve, and Craig!  If you want to hear us a...

With every big new paper or museum exhibition there will be artwork depicting dinosaurs as actual living animals, as well as all kinds of other representations of these animals be it pop-art or cartoons. Today we have a special with an extended chat to two artists who specialise in dinosaurs and make their living from producing images of these animals. They are Danielle Dufault who works for the R...

Way back in the mists of time (last year) we did a whole podcast on Triceratops , one of the most famous dinosaurs of all. But is Triceratops not all it seems and is it in fact just part of a growth series which results in the largest and oldest animals becoming another dinosaur entirely in Torosaurus ? The answer is no, but the reasons why this was proposed and why it's not the case are interesti...

We've covered one small, unadorned and under-rated herbivorous ornithischian already this series in Psittacosaurus and here's another one in the remarkable little heterodonotosaurs. Another set of animals for which we have some superb skeletons and lots of interesting features that are potentially very revealing about the evolution of dinosaurs in general (and ornithischians in particular) and yet...

Iszi is in Dave's house! We have talked many times about the fact that birds are dinosaurs and we've covered some of the modern evidence that links them together, but how did we get to this point? In this edition we look at the historical arguments for the origins of birds and how they went from a groups that had no obvious evolutionary home to some early flirtations with dinosaurs, places around...

We have talked before about how large some of the giant sauropods were and how being big can really affect your biology, but just how do palaeontologists weight dinosaurs from incomplete skeletons and how accurate will these methods be? Well happily we have a podcast that will tackle those very questions and delve into the history and mystery of working out how heavy dinosaurs were, how we used to...

It's time to give some love to some dinosaurs that don't get enough and pretty much top of that list needs to be Psittacosaurus . This (mostly) little dinosaur is one of the earlier ceratopsains but lacking the size, horns and frills of their more notable cousins, it's sadly all too easy to see why they get ignored. But that's a shame because as well as having some neat little features of their ow...

Riparovenator and Ceratosuchops – Chris Barker and Darren Naish Just like the start of series 3, we are kicking off the new series with a special on a new research paper (of which Dave is one of the authors) which is out today! In it, two new, large, predatory dinosaurs from the UK are named and both are part of the spinosaur group! Obviously it's all very exciting, but to avoid things being too D...

An interview about Marine Reptiles with Keirsten Formso @formophology. To get more free bonus content FIRST become a Terrible Lizards Patron on patreon.com/terriblelizards In the third series of Terrible Lizards we finally edged away from dinosaurs to cover pterosaurs, but in the Mesozoic, there were far more reptiles in the sea than in the air so we really need to do them too. Happily to this end...

It is the final episode this series and as usual we are answering some of your dinosaur questions (as many as we could cram into an hour). A massive thank you to all our patrons on patreon - your support means everything to us. We are planning a series 5! We will be back in the Autumn. There will be a few mid season episodes dropped here and even more content on our patreon. Got to patreon.com/ter...

Dave Hone tells Iszi Lawrence about the early days of paleontology and the very first dinosaur discoveries in the UK. We cover the perpetually unlucky Gideon Mantell and the not especially nice Richard Owen (and Mary Anning pops up though she didn't really do dinosaurs). Dr Kiki Sandford then joins us and asks what clues there are in fossils to tell us how dinosaurs behave... and things get silly....

Following on from our last adventure into the realm of the very biggest dinosaurs, we now have a look at the other side of this issue which is that big dinosaurs started off very small. How do you get from a 5 kg hatchling to a 50 ton monster and what does that mean for how they lived and how palaeontologists identify adults and juveniles? Are there hundreds of 'new' dinosaur species that are just...

Perhaps the single most notable feature of dinosaurs is the quite extraordinary sizes that many of them achieved. We have talked before about some of the issues surrounding being big, but before now we have not tackled the most obvious question in all of this: what is the biggest dinosaur? Well as you may expect by now this isn't a simple question to answer and between fragmentary fossil remains,...

This time out it is a group of dinosaurs very few people will have heard of or know very much about but they are a fascinating group of small, feathered theropods who have only been on the scene for around 20 years making them very much newcomers. The tongue-twistedly-named scansoriopterygidae are a bunch of fragmentary and bizarre animals from China and include some of the strangest dinosaurs kno...

Just how reliable are research papers and what goes on to get them published and accepted in the scientific literature and, critically, are they reliable? We have talked many times on the pod about scientific papers but without ever discussing what these actually are and how they get published. It's an important aspect of science and especially with palaeontology given the huge mix of information...
