5.1" Fossil Tyrannosaur Dorsal Vertebra - Judith River Formation

Fossil Tyrannosaur Dorsal Vertebra - Judith River Formation #187750

This is a nicely preserved, 5.1" long Tyrannosaur dorsal vertebra collected this summer from the Judith River Formation in Montana. There is only some minor stabilization and no restoration of the piece. It comes with a custom metal display stand.

There are multiple Tyrannosaurs (Albertosaurus, Gorgosaurus and Daspletosaurus) present in the formation, identifying an isolated bone like this to a particular species is mostly guesswork.

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 and non-avian dinosaurs (birds). 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.
