Tooth of the Hadrosaurid Dinosaur Edmontosaurus

Description: The hadrosaurs were a group of dinosaurs that lived in North America during theLate Cretaceous whose most distinguishing feature was a beak that earned them the common name “duck bills”. Their jaws were equipped with an extensive dental battery of up to 2000 teeth which were used to grind up vegetation. Some were known to have migrated in large herds and nested in extensive colonies. The hadrosaur Maiasaura is believed to have exhibited parental care of hatchling, a discovery made by Jack Horner well over 20 years ago. This is a single tooth from the extensive dental battery of this dinosaur named for the province of Edmonton, site of the original discovery of this large “duck-billed” dinosaur.
