So it turns out that our docile barnyard friends, the chickens, have quite a fearsome ancestor: T-rex. Asara et al. used mass spec to determine the amino acid sequence of collagen extracted from 68-year-old Tyrannosaurus rex bone. The determined sequence closely resembled that obtained from chickens. Of course most popular current hypothesis for the origin of birds is that they are the descendants of dinosaurs, but most of the evidence comes from anatomical structure. This is the first evidence to come from actual molecular data. Actually the most surprising thing about this study is that collagen survived 68 million years.
It doesn't quite mean the onset of Jurassic Park quite yet, but as my friend Thad said, "Barbecued or fried T-Rex sounds good!!"
