Hadrosaurs
The Hadrosaurs are commonly know as the "duck-billed dinosaurs". These large herbivores were both bipedal and quadrapedal and grew to a size of ~40 feet. They lived throughout the Cretaceous period, and believed to live in large groups. Fossil remains include well preserved teeth, bones, and claws. These top quality specimens were all legally collected from private lands in the northwestern US. Late Cretaceous, Hell Creek Fm. (or equivalent), 68-66 MYA.
Edmontosaurus was one of the largest members of the hadrosaur family which lived during the late Cretaceous in North America. These were large dinosaurs which grow up to 50 feet in length and weighed up to 10,000 lbs. Edmontosaurus was a herbivore who had a large bill-like snout that was able to nip and tear vegetation, and their jaws were filled with rows of large teeth used to grind vegetation. They appear to live in herds and they would be prey for Tyrannosaurus rex. Edmontosaurus had little defense when attacked by T. rex. They are believed to good speed for their size and a herd of large adults may have been have been threatening to a T. rex. There are two species of Edmontosaurus. There are two species of Edmontosaurus and in the Hell Creek formation, Edmontosaurus annectens was the species present.
Today, we find fossilized Edmontosaurus annectens teeth, unguals (claws), and non-associated bones in the Hell Creek Formation. Authenticity guaranteed.
