5.4" Tyrannosaur (Daspletosaurus?) Caudal Vertebra - Montana

This is a really cool, 5.4" wide Tyrannosaur (Daspletosaurus sp.?) vertebra from the Two Medicine Formation of Montana. It was collected this last spring and has been nicely prepared from the hard rock surrounding it. The centrum is overall in good condition with some weathering along the edges and small spots of gap fill restoration. Everything superior to the base of the pedicles was found separated from the centrum and required significant restoration to attach it back to the centrum. The processes weathered/broke away

It sits beautifully on the included custom metal display stand.

There are three described Tyrannosaurs found in the Two Medicine formation (Daspletosaurus, Gorgosaurus & Albertosaurus). An isolated vertebra would probably be indistinguishable between the three species. It was labeled as Daspletosaurus by the collector, since he believes most of the Tyrannosaur material he is recovering from the quarry is Daspletosaurus.

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.
