28.5" Hadrosaur (Maiasaura) Femur On Stand - Montana

This is a large, well preserved, 28.5" long Hadrosaur (Duck-Billed Dinosaur) femur from the Two Medicine Formation in Glacier County, Montana. We're typically hesitant to assign a species to individual bones when there are several species of Hadrosaurs described from the formation, but given the size Maiasaura peeblesorum is by far the most likely candidate.

The femur is laterally compressed but otherwise complete and well preserved with minimal surface erosion. There has been some repaired cracks and small gap fills in the cracks but that's it for restoration. It comes with a metal display stand which displays the piece nicely in a horizontal position.

Maiasaura meaning "good mother reptile" or "good mother lizard" is a large herbivorous hadrosaur ("duck-billed") dinosaur that lived in the area currently covered by the state of Montana in the Upper Cretaceous Period. The first fossils of Maiasaura were discovered in 1978. The name refers to the find of nests with eggs, embryos and young animals, in a nesting colony. These showed that Maiasaura fed its young while they were in the nest, the first time such evidence was obtained for a dinosaur. Maiasaura reached lengths of around 30 feet long, making it a fairly large Hadrosaur. Young animals walked on their hind legs, adults on all fours.
