In a post two months ago, I promised that I’d keep you updated with how my research is progressing. Needless to say, I’ve done a pretty poor job of that, unless you follow me on Twitter! I must apologise – the workload while traveling was severely under-estimated, and I’ve barely had time to catch a nip. I’m writing to you now from Lyon, where I finally had a day off in about a month to explore the Basilica and Roman amphitheater ruins here, and am now nestled in a snug pub hammering away at a manuscript!
My PhD consists of two parts. The first is investigating the dynamics of biodiversity across the Jurassic/Cretaceous interval about 145 million years ago. I want to see if when we consider the biases of the fossil record whether there was a ‘hidden’ mass extinction, and what were the ecological, physiological or environmental factors that correspond to this. This involves looking at turtles, birds, dinosaurs, marine reptiles, lizards, snakes, crocodiles and any other tetrapod group at the time – that’s anything with four feet, flippers or wings (see previous post for an update on all this jazz).
