3.3" Hadrosaur (Hypacrosaur) Vertebra with Metal Stand - Montana

 
 
 
 
 
 
This is a really cool, 3.3" wide Hadrosaur (Hypacrosaur) vertebra from the Two Medicine Formation of Montana. It was collected this last summer and has been nicely prepared from the hard rock surrounding it. Most of the cortical bone has weathered away, revealing the osteons (bone cells) that makeup the vertebra. There is no indication of any repair or restoration to this vertebra.

Comes with the pictured metal display stand.

Hypacrosaurus is a very large, Lambeosaurini Hadrsosaur that would have been almost as large as the Tyrannosaurs that it lived alongside. Like Corythosaurus, it had a tall, hollow rounded crest, although not as large and straight. It is known from the remains of two species that spanned 75 to 67 million years ago, in the Late Cretaceous of Alberta, Canada, and Montana, United States, and is the latest hollow-crested duckbill known from good remains in North America. It is estimated to have been around 9.1 meters (30 feet) long and to have weighed up to 4-5 tons.
