Terrible Lizards

Terrible Lizards is a podcast about Dinosaurs with Dr David Hone and Iszi Lawrence.

Available Episodes 10

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 camera and the steps that go into getting a dinosaur doc made and what goes on behind the scenes.

Dave has a fair old history with the more traditional media and you can see the fury coming out here too: https://archosaurmusings.wordpress.com/2010/03/22/linheraptor-vs-the-international-media/

 

Some great stuff can come from good documentaries though, check out this interview with the man behind the Walking with Dinosaurs models (and Jabba the Hutt!).

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-scientific ideas who present them as fully formed research. Rarely does any of this make it into the mainstream, but on occasion it leaks in and this can only cause confusion. So sit back and enjoy, or grind your teeth in quiet and cold fury, as we go over some of the issues that come with unscientific ideas trying to make their way into the mainstream.

It’s not just palaeontology that gets these people, here’s a neat blog on a physics crank, but the central themes are identical: https://www.skepticblog.org/2012/01/09/cranks-and-physics/

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.

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 to science. From there we move onto a new paper on pterosaur growth. We have covered this before with the idea that at least some pterosaurs grew very evenly and were independent pretty much on hatching. But this is a wider study with more species and suggests that the bigger pterosaurs were engaging in parental care with adults looking after their offspring for some time and shows there was more variation than previously thought.

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 learned and talks about digging a large hole with no dinosaurs in it while looking for a brachiosaur. It’s all very palaeontological, but that seems to suit our audience so here we are.

Dave’s not got his act together yet for photos of the trip but here’s some classic Morrison sauropods from the Morrison: https://archosaurmusings.wordpress.com/2011/11/11/a-pair-of-giants/

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 every sternum for every pterosaur out there and Iszi (hello!) gets to the bottom of why this is important for science and bad for Dave's mental health. 

Here is a link to Dave's blog: https://archosaurmusings.wordpress.com/2023/04/20/everything-you-didnt-think-to-ask-about-the-pterosaur-sternum-and-were-afraid-to-ask/?fbclid=IwAR3roJ1M-PgFO-53NZlPEXv--jkTo2xLTbh1okSC03QkeFY4nFnjZ_TELVw

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 the Middle Jurassic of China but has not had all the research attention that it should for a such an interesting animal that’s known from a good amount of material and a time where dinosaur remains are generally sparse. Happily, a major new study is out on these animals which adds some nice new information and potentially resolves some longstanding issues with this awesome genus so buckle up for some important tales of neck elongation in the Mesozoic.

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 happily Dave is going to talk through some more of it again, with a side dabble into another bit of dinosaur behaviour and looking at predation vs scavenging.

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 through editors, subeditors, producers, directors, animators and whole panels of discussion and you have very little control over it. That means that even the best communicators can have their message badly distorted by those who don’t, or should, know better and has profound effects on the public understanding of science and where scientists fit into it.

So listen to Dave describe (OK, rant) about all the ways this goes wrong and what it means for the audience and palaeontologists alike. Iszi does get a word or two in as well.

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 constraints and compromises necessary and how to try and cater for all. Unsurprisingly, it’s rather complex to balance space, time, money, science, accessibility and protect the fossils on display. Hopefully, it gives some insight into how these things come to be and how they are supposed to work at least.

We also cover whether T Rex and other theropods had primate like numbers of telencephalic neurons and what this means. Were they really like baboons?
