Thescelosaurus DinosaurDescription: Thescelosaurus was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Tertiary extinction event around 65.5 million years ago. This genus of dinosaur is regarded as a specialized hypsilophodont and an herbivore.

Thescelosaurus had a small head, a bulky body, a long, pointed tail, and short arms. It was about 10 to 13 feet (3-4 m) long and 3 feet (0.9 m) tall at the hips; it weighed roughly 665 pounds (300 kg). This ornithopod ( Hypsilophodontid) had a small skull, cheek pouches, cheek teeth, and a beak made of horn.

Several Years ago a specimen was unearthed known as Willo which contained an iron stained concretion in the chest region which is thought to have been the herart.
