Hadrosaur Vertebra From Hell Creek Formation

 
 
 
 
This is a 2.7" wide and 6 inch long (including process) tail vertebra from Edmontosaurus annectens more commonly referred to as a "Duck Billed Dinosaur" It comes from the Hell Creek Formation of South Dakota. There are a few repaired cracks in the process but no restoration. It's a nice quality Hadrosaur vert.

This specimen was found at a private ranch in Butte County, South Dakota this summer. It comes from a quarry known as the "Tooth Draw Quarry" that has produced many high quality dinosaur teeth over the past several decades. In the Late Cretaceous some 65 million years ago, this quarry was located in a sub-tropical floodplain that would have been similar to modern day coastal Louisiana. It consists of 2 meters of alternating sandstone and gravel, representing a river channel lag deposit. It contains many isolated dinosaur teeth including T-Rex, Nanotyrannus, Raptors and Triceratops, but teeth of this high quality are rare finds.

Hadrosaurs are 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.
