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.   Links: support us on patreon and access extra content:  www.patreon.com/terriblelizards   A link to Melanie’s YouTube series which is on long term hiatus but full of cool videos to watch (even if it notably fails to include a certain silver-haired pterosaur and tyrannosaur researcher): https://www.youtube.com/c/GenuineRockstars/videos   Here’s a link to Melanie’s press stuff for her papers but it includes some videos and graphs of that we talk about https://uppsala.app.box.com/s/ikmlwtb0vui7zn5k74jfokbhysla8ck1
