4.7" Fossil Dinosaur (Thescelosaurus) Dorsal Vertebra - Montana

This is an exceptionally well preserved, 4.7" tall dorsal vertebra from the ornithischian dinosaur, Thescelosaurus neglectus, collected from the Late Cretaceous Hell Creek Formation in Powder River County, Montana. The bone preservation is fantastic, with both transverse processes, the spinous process, both prezygapophyses, and one postzygapophysis remaining mostly intact.

It is accompanied by the pictured wood display stand.

There are a couple repaired cracks through the three processes with minimal gap fill restoration required. Both prezygapophyses have repaired cracks near their bases, and the same can be said for the left postzygapophysis. The restoration makes up approximately 1% of this spectacular dinosaur fossil.

About Thescelosaurus

Thescelosaurus was a small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. Many specimens' preservation and completeness indicate that Thescelosaurus may have preferred to live near streams.

This bipedal ornithopod is known from several partial skeletons and skulls, all of which indicate adult lengths between 2.5 and 4.0 meters (8.2 to 13.1 feet) on average. It had sturdy hind limbs, small wide hands, and a head with an elongated pointed snout. Their teeth and jaw morphologies suggest a primarily herbivorous diet.

The Hell Creek Formation

Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
