3.19" Edmontosaurus (Hadrosaur) Caudal Vertebrae - Montana

Edmontosaurus (Hadrosaur) Caudal Vertebrae - Montana #10756

This is a 3.19" wide mid-caudal (center of tail) vertebrae of Edmontosaurus annectens a type of Hadrosaur. It was found in the Hell Creek Formation, at a quarry in Powder River County, Montana. The bone has quite a bit of weathering with only a few spots of the shiny, smooth outer bone remaining. The processes have all eroded away and all that remains is the vertebra body. There have been a few crack repairs and restoration on one of the ends.

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.
