Riachardoestesia, Theropod Dinosaur tooth, Late Cretaceous, North America.

Richardoestesia was a theropod Dinosaur that lived in what is now known as North America. Two species are known which are R. Gilmorei and R. Isosceles, the latter being the one available with us to purchase.

Not a huge amount is known as yet of this species of dinosaur, but we do know that they were widely spread throughout North America and the teeth are found in almost all fossil deposits and micro sites.

These teeth are a superb addition to a fossil collection and are a unique tooth, this tooth was found at Powder river county, Montana, Hell Creek.
