7.9" Hadrosaur (Edmontosaurus) Metatarsal - Wyoming

Hadrosaur (Edmontosaurus) Metatarsal - Wyoming #233808

This is a 7.9" long metatarsal bone of a hadrosaur (Edmontosaurus annectens), collected from our partner's lease on the Lance (Creek) Formation in Niobrara County, Wyoming.

There is crack repair and glue stabilization towards the proximal end of the bone where it was found heavily fragmented. A good sized chunk of bone is missing from the distal epiphysis.

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.
