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 As always do consider supporting us on Patreon and unlock extra content: https://www.patreon.com/terriblelizards

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.    Links: A very short blogpost by Dave with a photo of the mounted Bellusaurs skeleton:  https://archosaurmusings.wordpress.com/2010/01/16/bellusaurus/   And a post on the insanely long Mamenchisaurus sinocanadorum cervical rib: https://archosaurmusings.wordpress.com/2008/06/27/biggest-bones/ 

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.  Links: A blog post Dave forlornly wrote as a guide for journalists writing about science but serves as a useful guide for most people for spotting bad science journalism: https://archosaurmusings.wordpress.com/2011/10/20/traps-for-journalists-to-avoid/  A blogpost by palaeontologist Mark Witton about what can happen when a TV show tries to bring dinosaurs (on this case, pterosaurs) to life even when experts are involved: http://pterosaur-net.blogspot.com/2011/01/what-despair-pterosaurs-and-david.html 

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?   Links: A blog post about the little exhibition on pterosaurs Dave put together way, way back in 2007: https://archosaurmusings.wordpress.com/2008/10/10/the-great-pterosaur-exhibition-of-2007/   A website covering the Titus exhibition that Dave helped to create: https://fourfamilyadventures.co.uk/titus-t-rex-is-king-wollaton-hall-nottingham/   The paper we discuss: https://onlinelibrary.wiley.com/doi/epdf/10.1002/cne.25453
