10.1" Hadrosaur (Edmontosaurus) Metatarsal - Wyoming

Hadrosaur (Edmontosaurus) Metatarsal - Wyoming #233811

This is a 10.1" long metatarsal bone of a hadrosaur (Edmontosaurus annectens), collected from our partner's lease on the Lance (Creek) Formation in Niobrara County, Wyoming.

There are multiple repaired cracks through the specimen where the bone fragmented. Gap fill restoration restoration can be found within the repaired cracks in areas where the bone crumbled away. The largest area of restoration is along the medial edge through the distal epiphysis, continuing through the the distal end of the diaphysis. A chunk of bone is missing from the anterior edge of the proximal 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.
