17" Long Triceratops Rib Section - South Dakota

This is a 17" long rib section from one of the most iconic dinosaurs Triceratops horridus. It comes from the Hell Creek Formation in South Dakota, making it approximately 66 million years old. The rib section is pretty solid with a few repaired cracks and no restoration.

It comes with the pictured, acrylic and brass display stand.

This specimen was found at a private ranch in Butte County, South Dakota this summer. It comes from a quarry known as the "Tooth Draw Quarry" that has produced many high quality dinosaur teeth over the past several decades. In the Late Cretaceous some 65 million years ago, this quarry was located in a sub-tropical floodplain that would have been similar to modern day coastal Louisiana. It consists of 2 meters of alternating sandstone and gravel, representing a river channel lag deposit. It contains many isolated dinosaur teeth including T-Rex, Nanotyrannus, Raptors and Triceratops, but teeth of this high quality are rare finds.

About Triceratops

Triceratops was one of the most iconic North American dinosaurs, living during the Late Cretaceous around 68–66 million years ago. With its enormous frilled skull and three horns, it was an impressive sight and may have used its headgear for display as much as for defense against predators like Tyrannosaurus rex. Adults could grow up to 9 meters (29.5 feet) long, stand about 3 meters (9.8 feet) tall, and weigh as much as 26,000 pounds. Its sturdy build and powerful horns made it a formidable herbivore capable of standing its ground against large predators.



Triceratops had highly specialized teeth arranged in groups called dental batteries, with dozens of tooth columns lining each side of its jaws. Each column contained several stacked teeth that were constantly replaced, giving it hundreds of teeth over its lifetime. This unique system allowed Triceratops to efficiently chew tough, fibrous plants such as ferns, cycads, and palms. Triceratops was designated as the state fossil of South Dakota in 1988.
