3" Allosaurus Caudal (Tail) Vertebrae - Colorado

This is a 3 inch long caudal (tail) vertebrae from the most well known Jurassic predator, Allosaurus. The process is broken off as is the base with most verts, but it has a nice exterior surface to it with minimal erosion. It is a very solid bone with no restoration or repair.

Allosaurus was a theropod of the Late Jurassic that lived from 156 to 145 million years ago. It was a predator with a massive skull, serrated teeth, and gaping jaws. This powerful and plentiful carnivore genus could grow more than 30 feet long. Due to how plentiful it's fossils are in the Morrison Formation, it's been suggested that they may have been a pack hunter.
