Edmontosaurus Bone in Sandstone Matrix- Wyoming

A fragment of Edmontosaurus bone embedded in a sandstone matrix, recovered from the Lance Formation in Wyoming. This site is renowned for its abundance of Edmontosaurus fossils, often referred to as a vast hadrosaur graveyard, making it highly likely that unearthed specimens belong to this species.

The Lance Formation in Wyoming, a geological formation from the Late Cretaceous period, is known for its rich fossil content, including the remains of hadrosaurs, a group of duck-billed dinosaurs. Among the most intriguing discoveries from this region are the fossilized tendons of these hadrosaurs, which offer unique insights into the anatomy and physiology of these prehistoric creatures.
