7.9" Fossil Hadrosaur (Brachylophosaur) Metacarpal on Stand - Montana

 
 
 
This is a nice, 7.9" long fossil hadrosaur (Brachylophosaur) metacarpal (hand bone) from the Judith River Formation of Montana. Repair through the diaphysis of this bone is minimal. Both the proximal and distal epiphysis and metaphysis have repaired crack which required gap fill restoration.

Comes with the pictured custom metal display stand.

The Judith River Formation is one of the most prolific sources of Late Cretaceous vertebrate fossils. At least sixteen Orders containing more than forty Genera are known from the formation. These include fish, amphibians, mammals, and insects in addition to the reptiles, avian and non-avian dinosaurs (birds). Among the more interesting specimens is Leonardo, a mummified and fossilized Brachylophosaurus. This is a Hadrosaur, a duck-billed dinosaur with amazing preservation of the soft tissues of the body. The pattern in the skin of the feet is even preserved. In addition to Leonardo, the Judith River Formation contained the remains of the theropod Hesperornis, the only known freshwater Hespernorthid, a penguin like bird.

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.
