Sometimes, it can be difficult to figure out how ancient organisms used to eat. Part of the problem is that we can never actually see extinct animals eating (until we invent time-travel.. *taps fingers impatiently at physicists*), and often it can be hard to work out how something ate based just on its anatomy. Sometimes though, the fossil record chucks up something truly spectacular, and gives us amazing insight into the spectacular diversity of ancient life.
Dinosaurs. What springs to mind when they’re mentioned? Colossal, towering sauropods? Packs of feisty feathered fiends? Or huge herds of hadrosaurs, chomping their way across the plains of long-lost worlds? Most, including myself, will automatically default to any one of these images when dinosaurs come up in conversation (what, you mean it’s not that frequent for normal people?) But we often neglect to think the earliest dinosaurs, spectacular organisms that gave birth to the most successful, and on-going, terrestrial vertebrate radiation of all 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?
