Maiasaura Vertebra - 3.75" Fossil

Maiasaura Vertebra - 3.75" Fossil

Maiasaura was a large Ornithischian dinosaur from the Cretaceous Period. Related to Iguanodons, they are known primarily for nurturing their young past hatching, a behavior previously unknown of any dinosaur.

The Maiasaura and its Hadrosaur cousins had specialized "duck-bills" for mouths. These were in fact elongated rostral bone structures that gave the appearance of a beak, but actually housed hundreds of small teeth to grind through all manner of plant material, including rotten wood.

This specimen is a 3.75" Maiasaura Vertebra recovered from private land on the Two Medicine Formation in Montana. It is estimated to be over 74,000,000 years old and comes with a certificate of authenticity.
