Chaaaaange places! Sometimes, when extinction hits it’s not quite the dramatic ‘great dying’ we might think of where animals choke their final breaths out in the desolate, lifeless wastelands. Sometimes, it’s more like the Mad Hatter’s tea party from Alice in Wonderland: chaotic, messy, no major character dies, but you can be sure that something pretty weird and dramatic has just happened.
Well, I think this is what happened around 145 million years ago at the Jurassic/Cretaceous boundary. In a recent paper, we analysed the diversity and extinction patterns of crocodyliforms – the group that includes modern crocodiles and their super cool ancestors – and found that they got hit pretty hard by an extinction event around this time.
Crikey, it’s been 3 months already?! *panics* At Imperial College, new PhD students have to produce an initial plan of study within the first three months of setting off, and submit it for independent assessment. Having uploaded mine just now (not in the slightest bit late..), I figured I’d share it here! It’s a broad outline of what I’m aiming to do for the next wad of months – any comments or feedback will be massively appreciated!
Proposed title of thesis: Diversity crash at the Jurassic/Cretaceous boundary: a forgotten mass extinction?
