Hypacrosaurus was a large Ornithischian dinosaur from the Cretaceous Period. Related to Iguanodons, they are known primarily for their "duck-bills" which are in fact elongated rostral bone structures that give the appearance of a beak, but actually housed hundreds of small teeth that allowed these giant herbivores to grind through all manner of plant material, including rotten wood.

This specimen is a 2.08" Hypacrosaurus Vertebra recovered from private land on the Two Medicine Formation in Montana. It is estimated to be over 75,000,000 years old and comes with a display stand and certificate of authenticity.
