Theropod and Ceratopsid Tooth Association - Judith River Formation

This is an interesting natural tooth association that includes a theropod and ceratopsid dinosaur shed ("spitter") tooth, collected from the Judith River Formation of Montana. They have been partially exposed from the rock they were found in, creating a gorgeous in situ presentation. Based on the ridges of an additional fossil within the rock, it's likely that there is also a partial garfish scale that has been exposed. The teeth have undergone no repair or restoration!

It comes with an acrylic display stand.

Measurements:
Theropod tooth - .47" long (straightline measurement)
Ceratopsid tooth - .52" long
Entire specimen - 4.1 x 3.1"

Due to the variety of theropod and ceratopsian species that come out of the Judith River Formation, it is difficult to assign a specific species to these teeth. With the theropod tooth, the lack of serrations along the exposed edge makes it almost impossible to provide a genus.

The Judith River Formation is one of the world's most prolific sources of Late Cretaceous vertebrate fossils. At least sixteen Orders containing more than forty Genera are known from the formation. These include fish, amphibians, mammals, and insects in addition to reptiles and avian (birds) and non-avian dinosaurs. Among the more interesting specimens is Leonardo, a mummified and fossilized Brachylophosaurus. This is a hadrosaur, a duck-billed dinosaur found with amazing soft-tissue preservation: skin impressions can be found on 90 percent of its body! The pattern in the skin on its feet is even preserved. In addition to Leonardo, the Judith River Formation contains the remains of the theropod Hesperornis, the only known freshwater Hespernorthid, a penguin-like bird.
