Richardoestesia gilmorei Tooth | Hell Creek Fm. | Montana

A nice theropod tooth crown (cf. Richardoestesia gilmorei) from the Late Cretaceous Hell Creek Formation.

Richardoestesia was a small, enigmatic theropod equipped with long, narrow jaws and dozens of closely packed teeth, likely specialising in snaring fish, small amphibians, and aquatic prey along Cretaceous river systems. The gilmorei morphotype is distinguished from its straight-toothed relative, R. isosceles, by its distinctive backward curve and minute, square-shaped serrations.

The formation where this tooth was found, the Hell Creek Formation, was laid down by ancient floodplains in the Late Cretaceous and preserves fossils of Triceratops and Tyrannosaurus, as well as many other well known dinosaurs. Its top, the K-Pg boundary, marks the asteroid impact that ended the dinosaurs.

The tooth comes stored in a display box featuring the specimen name, region it was found and age.

This is genuine fossil. All the specimens we offer come with a lifetime authenticity guarantee.
