Question: Which Dinosaur Had 500 Teeth?
Answer: Nigersaurus is a genus of rebbachisaurid sauropod dinosaur that lived
during the middle Cretaceous period, about 115 to 105 million years ago.
It was discovered in the Elrhaz Formation in an area called Gadoufaoua,
in the Republic of Niger. Fossils of this dinosaur were first described in
1976, but it was only named Nigersaurus taqueria in 1999.
Nigersaurus was about 9 m (30 ft) long and had a short neck. It weighed
around 4.4 short tons, comparable to a modern elephant. It had a wide
muzzle filled with more than 500 teeth, which were replaced at a rapid
rate: around every 14 days.
