Large Edmontosaurus Jaw and Tooth in Riker Box — Hell Creek Formation, North Dakota (66 MYA)

A larger display piece from a duck-billed dinosaur. This genuine Edmontosaurus jaw fragment and tooth fragment was collected from the Hell Creek Formation of North Dakota and dates to the Late Cretaceous, about 66 million years ago. Both pieces are displayed together in a labeled Riker box.

This is the exact piece you will receive. It is a one-of-a-kind set, so what you see in the photos is what ships.

Edmontosaurus was a duck-billed dinosaur that roamed the Late Cretaceous floodplains of North America, famously traveling in massive herds. It was one of the last and most successful plant-eating dinosaurs before the mass extinction that ended the Age of Dinosaurs, and it lived alongside T. rex and Triceratops.

The jaw fragment shows the texture and structure of the bone that once held its complex battery of grinding teeth. The tooth fragment represents part of that unique chewing system, a key adaptation that helped Edmontosaurus process tough vegetation.

A great fit for fossil collectors, educators, classrooms and museum-style displays.
