STENEOSAURUS

extinct genus of early crocodiles found as fossils in Jurassic rocks (208 to 144 million years ago) of South America, Europe, and North Africa. Its skull was very light and narrow, with large openings and a long and narrow snout. The nostrils, at the tip of the snout, were connected to the throat by a long bony tube. Many sharp teeth were present; Steneosaurus probably subsisted on fish.
