.31" Fossil Raptor Tooth in Sandstone - Two Medicine Formation
This is a rare .31" long, fossil raptor tooth collected from the Two Medicine Formation this summer. The tooth is compressed and has been partially exposed from the rock it was found in. The serrations are visible along one edge, but will require magnification to see in detail. The rock measures 5.7 x 3.6" and comes with an acrylic display stand.
Smaller theropods like Velociraptor typically did not use their teeth for killing and so their teeth are much smaller in size in relation to their skulls when compared to larger therapods that used their teeth as the primary killing tool.
Theropods from the Two Medicine Formation were quite abundant, especially the relatively small species. The largest of these theropods were the tyrannosaurids Daspletosaurus torosus and Gorgosaurus libratus. Where dromaeosaurids are concerned, Bambiraptor feinbergorum, Dromaeosaurus albertensis and Saurornitholestes langstoni species have been identified from this location.

The Two Medicine Formation is a geographical formation in Central Montana and Southern Alberta, Canada. The formation is predominantly sandstone laid down by rivers and deltas during the Campanian Age of the Cretaceous, about 80-75 million years ago. Approximately two thousand feet thick on the western edge, it lies on top of the Virgelle Sandstone formation and under the Bearpaw Shale. It is located between the Front Range of the Rocky Mountains and the Sweetgrass Arch, a tectonic fold feature 40-90 miles east of the Front Range.
The Two Medicine is the same age as the Judith River Formation found further east. It was laid down further inland from the Western Interior Seaway, while the Judith River Formation was deposited along the coast. The Two Medicine contains much of the same dinosaur fauna, but fewer reptiles, amphibians, and aquatic fossils.
