Kentucky fried T-Rex parts?
Protein retrieved from a 68 millon-year-old Tyrannosaurus rex bone closely resembles the main protein in chicken and ostrich bones and is only distantly related to lizards’, strengthening the popular idea that birds, and not reptiles, are the closest living relatives of dinosaurs.
The new work builds on a 2007 analysis showing remarkably close similarities between T. rex collagen and collagen from modern-day chickens, but that work did not include comparisons to other living species. Collagen is the primary protein in bones.
