Set Of 4 Hadrosaur Edmontosaurus Tail Vertebrae
Here is a great set of four Hadrosaur tail vertebrae from the famous Hell Creek Formation in Montana. They range from 2.3 inches in length to 1.5 inches.These tail verts were found under the surface of the rock and prepared to remove them from the matrix. No restoration has been done to them.
Hadrosaursare frequently referred to as duck-billed dinosaurs and are members of the ornithischian family Hadrosauridae They were fairly common herbivores which roamed Asia, Europe and North America during the Upper Cretaceous Period. Many species of hardrosaurs had distinct crests on their head, some of which had air filed chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.
