This National Science Foundation website presents a multimedia news story about the discovery of the fossilized bones of an as of yet unknown crocodile in Tanzania. The short video at the top of the page is very informative, and it features the narration of Patrick O'Connor, a paleontologist at Ohio University. The video explains that the characteristics of the crocodile are much more mammalian than amphibian. Visitors will learn that the variety of tooth types in its jaw, its smaller size, and its nostril placement are all indicative of an animal that maneuvered and lived much like a mammal. The "Discovery" link has an article several paragraphs long about the new-found crocodile, as well as photos from the site where the paleontologists were exploring when they found the fossilized bones. Visitors can also view a brief video of X-ray computed tomography that was used to create detailed digital images of its teeth, and move them to mimic to a fine degree the actual movement of the crocodile's jaw. Under the "Downloads" menu there are many more pictures of the site and the people on the expedition.
