Scientists in the US have likely confirmed the presence of intact dinosaur collagen in specimens as old as 80 Ma using a combination of techniques including microscopy, histochemistry and mass spectrometry.
Positive reactions were obtained using antibodies specific to bones of modern birds, suggesting the proteins originally found in fossils in 2005 were indeed Dinosaurian in origin.
The study also details results suggesting the presence of Dinosaurian DNA although no sequencing was completed to confirm the origin (see our last post ).
The results were presented last week at the annual meeting of the Society of Vertebrate Paleontology.
