Nigersaurus had a delicate skull and an extremely wide mouth lined with teeth especially adapted for browsing plants close to the ground. This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than 500 replaceable teeth.

What dinosaur has 1000 teeth?

Nigersaurus -- so named because it was discovered in Niger -- had the long neck of a Diplodocus and up to 1,000 teeth in its intricate jaws, Sereno, of the University of Chicago, said on Monday. The bones of the 1,000-toothed "lawnmower" which scythed across west Africa were found first by a French researcher.

Who discovered the dinosaur with 500 teeth?

Nigersaurus was suggested by Sereno and colleagues to be a ground-level, non-selective browser. The width of the muzzle and lateral orientation of the tooth row show that the sauropod could gather much food and crop it close to the ground, within 1 m (3 ft 3 in) of the surface.
