SCHMID, AP Science Writer Thu Nov 15, 12:40 PM ET WASHINGTON - Perhaps it was one of those eureka moments, when the scientists realized they had discovered a new dinosaur with mouth parts designed to vacuum up food. The 110 million-year-old plant eater, discovered in the Sahara Desert, was to be unveiled Thursday by the National Geographic Society. Discoverer Paul Sereno named the elephant-sized animal Nigersaurus taqueti, an acknowledgment of the African country Niger and a French paleontologist, Philippe Taquet. Sereno, a National Geographic explorer-in-residence and paleontologist at the University of Chicago, said the first evidence of Nigersaurus was found in the 1990s and now researchers have been able to reconstruct its skull and skeleton. While Nigersaurus' mouth is shaped like the wide intake slot of a vacuum, it has something lacking in most cleaners — hundreds of tiny, sharp teeth to grind up its food. The 30-foot-long Nigersaurus had a feather-light skull held close to the ground to graze like an ancient cow. Sereno described it as a younger cousin of the North American dinosaur Diplodicus. Its broad muzzle contained more than 50 columns of teeth lined up tightly along the front edge of tis jaw. Behind each tooth more were lined up as replacements when one broke off.
