We’ve made plenty of jokes over the years about the general lack of sauropod skulls and the frustrations of trying to work out what these animals were doing when it came to things like feeding when the most important bit is missing. Happily, this week we are joined by David Button who has done a ton of work in this area and is happy to chat to Dave and Iszi about how their heads and teeth were built and what this can (and can’t) tell us about their diets and habits. While we have him trapped, we also quiz him on his recent work on the behaviour of the thescelosaurs, an odd branch of dinosaurs we’ve taken till series 10 to even mention!

And old post of Dave’s on the sauropod skeletons in Berlin, that really show off the issue of different feeding heights in these animals: https://archosaurmusings.wordpress.com/2013/01/27/berlin-sauropods/

The spinosaurs get all the love (OK, mostly hate) and attention when it comes to the megalosauroids, but they are but one weird branch of this group of theropods. Sadly they have a similar problem to the spinosaurs in that there are annoyingly few fossils of them, and there’s very few people working on these animals. Happily, today Iszi and Dave are joined by one of them, Cass Morrison who is doing his PhD on these unusual animals and is here to give us the lowdown on their evolution, diversity, biogeography and ecology and generally fill us in on these much under-appreciated animals.

We have touched on the extinction that killed the dinosaurs plenty of times before over the various seasons of TL, but we have never really tackled it fully before. Finally, we are joined by a real expert on this subject, Melanie During who is in the process of finishing her PhD on this very subject. So prepare for not actually really any dinosaurs, but quite a lot of geology and geochemistry to learn how the impact was so utterly devastating and how we know. It turns out that they never stood a chance and that the damage was even worse than even Dave had realised.
