PRODUCT OVERVIEW

Carnotaurus is a carnivorous predatory dinosaur from the Upper Cretaceous. It lived approximately 70 million years ago. The only specimen ever found was excavated in Argentina.

The Carnotaurus had a length of 9 metres and an estimated weight of 1.5 to 2 tons. His jaw was more rounded than that of his relatives, and his teeth looked like bended knife blades. Surely it was one of the most dangerous predators of its time.

- Fun Fact : The name Carnotaurus means "meat-eating bull". - Scientific Name : Carnotaurus sastrei This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 5310-00-095-3775, indicating validated use in U.S. government and defense logistics supply chains.
