Goniopholis (crocodile) (GO-nee-AH-foh-liss)
Teeth and pieces of body armor (called scutes) from crocodilians are common finds in the Cretaceous clays of Maryland. The teeth were pointed and cone-shaped, different from the serrated, knife-like teeth of most predatory dinosaurs. The scutes, with their distinctive "dimpled" pattern, were embedded in the skin and probably covered with keratin, the same material that forms your fingernails. Although these crocodilians were very similar to their modern relatives in size, shape, and diet, many species living elsewhere in the world during the Cretaceous were very different. Some had evolved radically different teeth, suggesting unusual diets and feeding behaviors. Others walked (or ran) on upright legs, a form of movement unlike that used by their splay-legged modern relatives. The animal depicted in the painting is Goniopholis, which ranged across North America, Europe and Asia.
