Nigersaurus Grazed Much Like a Cow

Scientists have long believed that long-necked dinosaurs grazed from the leaves in the trees, but further studies of a dinosaur species discoverd in Niger in the 1950s, now leads scientists to believe some of these long-necked creatures actually grazed from the ground much like a cow would. The Nigersaurus had around 500 teeth with 10 rows of back up teeth crammed in. It is believed that they replaced teeth faster than any other known dinosaur. The angle of the jaw, the orientation of the ears and the fragility of the backbone and skull all point to the Nigersaurus as being a grazer.

This artist rendering makes the dino look a bit like it has a hippo head, don't you think?

This computer generated image doesn't make him look like a hippo, but I can't see where those teeth are. This vision does have a very cow like quality to it. Check out that tongue! Have you ever been licked by a cow? I have. Yikes!
