Fossil Hadrosaur Tooth & Turtle Bone in Rock - Judith River Formation

This is a 4.1" wide piece of sandstone that contains a hadrosaur (Brachylophosaurus canadensis?) tooth and a 2.35" long fossil turtle bone (appendage or pelvic/shoulder girdle), collected from the Judith River Formation in Montana. While scutes are quite common in the formation, turtle skeletal elements are very uncommon. A variety of bone fragments have also been exposed from the rock, as well as a partial turtle scute on the back side of the specimen.

There is one repaired crack through the diaphysis of the bone. Comes with an acrylic display stand.

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.
