6.5" Hadrosaur (Maiasaura) Rib Section On Metal Stand - Montana
This is a 6.5" long, rib section of a Hadrosaur (Maiasaura) collected recently from the Judith River Formation of Montana. It comes with a custom metal stand for display.
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.
