Edmontosaurus Rib- Wyoming

This well-preserved fossil is most likely a rib from an Edmontosaurus, a large duck-billed dinosaur from the Late Cretaceous of Wyoming. Collected from the Lance Formation, the specimen shows excellent surface detail and natural curvature typical of hadrosaur ribs. It has been repaired in multiple areas but remains a solid and display-worthy example of this iconic herbivore.

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.

Characteristics of Fossilized Tendons: Fossilized tendons in hadrosaurs are primarily ossified tendons, which means they have undergone a process of mineralization, turning them into stone. These tendons are typically found along the spine and tail of the dinosaur. In life, these tendons would have provided support and stability to the animal's body, especially important for large, bipedal or quadrupedal creatures like hadrosaurs.
