UNCINATE IN ARCHOSAURS, A TALE OF CAPTAIN HOOK IN THE FOSSIL RECORD

Archosaurs are a major group of vertebrates that include living birds crocodylians, and fossil dinosaurs. On several dorsal ribs in living birds and crocodylians, we can find uncinates, which are hook-like or tab like protrusions located at the back side of the ribs. We use anatomical and histological methods to identify the presence of uncinates in fossil archosaurs. The data we have been collecting from North American and Chinese archosaurs suggest that uncinate is likely a feature shared by many if not all archosaurs.
