Reptiles of the Hell Creek Formation

Reptiles of the Hell Creek Formation — Late Cretaceous (66 Million Years Ago)

Discover the ancient reptiles that thrived alongside the last dinosaurs with this authentic fossil collection from the Hell Creek Formation of North Dakota. Each specimen in this set represents a different creature that once shared the Late Cretaceous landscape — from the swamps and rivers to the forested floodplains.

This set includes:

Triceratops frill fragment – part of the armored crest of the famous three-horned dinosaur

Edmontosaurus tooth fragment – from the duck-billed herbivore that grazed the Cretaceous plains

Turtle shell fragment – from ancient freshwater turtles that swam in the rivers of Hell Creek

Crocodilian osteoderm fragment – a piece of the bony armor that protected ancient crocodiles

Champsosaurus vertebra – from a semi-aquatic reptile resembling a modern gharial

Together, these fossils paint a vivid picture of the ecosystem that existed just before the extinction of the dinosaurs, 66 million years ago. Each authentic specimen is displayed in a labeled Riker box for protection and presentation, ideal for collectors, educators, and paleo enthusiasts.
