A Cretaceous croc named "Shield Croc" with a long snout and the largest known crocodile brain has been discovered in Morocco. It has a shield-like plate on its head and an "eyespot" that was perhaps used during courting displays. Dr. Holliday suggests the Cretaceous may not have been the age of dinosaurs, but rather the age of crocodiles.
