3" Fossil Hadrosaur Vertebra With Stand - Judith River Formation

This is a nicely preserved, 3" tall Hadrosaur vertebra that was collected from the Judith River Formation of Montana. The centrum was found broken within the rock, requiring crack repair and some gap fill restoration to piece back together. A large section of the edge of this vertebra has undergone significant restoration. The processes of this vertebra have weathered away.

The entire specimen stand 4.8" tall on the accompanied metal display stand.

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 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.

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 contains the remains of the theropod Hesperornis, the only known freshwater Hespernorthid, a penguin like bird.
