The type of Dinosaur with 500 teeth is the Nigersaurus Dinosaur which lived almost 1100 years ago in the central region of North Africa.

Nigersaurus Dinosaur

Nigersaurus dinosaur is classified based on its huge amount of teeth, i.e., 500 teeth. Its upper jaw has 60 columns of needle-shaped, small teeth. And almost 68 columns of teeth were present in its lower jaw. The genus is Rebbachisaurid sauropod which includes huge herbivorous dinosaurs and diplodocus animals. It walked on its four legs.


The generic name of Nigersaurus means it is a niger reptile. It was first discovered by a French palaeontologist named Philippe taquet. That’s why its specific name is ‘Taqueti’ in the landlocked West African country in 1976.  A complete and more extensive discovery was made on the site in late 1999 by an American palaeontologist Paul Sereno. The research was done in the Elrhaz Formation in an area called Gadoufaua, in Niger. The scientist gave him the name “Nigersaurus taqueti” after that complete study.

Its origin is believed to be from the central region of North Africa, and other more remains were found in Niger, Algeria, and Tunisia. The genus name Nigersaurus refers to the country where they first found it. The remains of Nigersaurus are in the display at the National Museum of Niger. Firstly, Sereno and Jeffrey A. Wilson provided a detailed description of the dinosaurs. The second detailed description was published by Sereno and his other colleagues in 2007.
