1.6" Fossil Hadrosaur (Edmontosaurus) Skin - Montana

Fossil Hadrosaur (Edmontosaurus) Skin - Montana #133486

This is a unique and rare, 1.6" wide piece of Hadrosaur (Edmontosaurus sp.) "dinosaur skin" that was collected from the Hell Creek Formation in Dawson County, Montana. This rare preservation occurs when the dinosaur is covered in sediment soon after death. The sediment then hardens around the skin, creating a negative cast prior to decomposition. The open space following decomposition is then filled in with rock, resulting in a positive cast of the dinosaur's skin.

Hadrosaurs

are frequently referred to as duck-billed dinosaurs and are members of the Ornithischian family Hadrosauridae. They were fairly common herbivores that roamed Asia, Europe, and North America during the Upper Cretaceous Period. Many species of Hadrosaurs had distinctive crests on their heads, some of which had air-filled chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.
