21.6" Triceratops Mandible (Lower Jaw) On Stand - Wyoming
This is a 21.6" wide mandible bone of a marginocephalian (likely Triceratops horridus) from the Late Cretaceous, or roughly 66 million year old Lance Creek Formation of Wyoming. It was found heavily fractured and fragmented within the rock, requiring significant restoration and crack repair throughout. The head of the mandible has been completely restored, with gap fill restoration continuing through the ramus and down across the body. The restoration in the specimen is hard to miss and can be identified by its smooth texture. A neat feature of this specimen is the preserved foramen that would have housed blood vessels and nerves. These can be found along the distal end of the mandible on the labial side.
This specimen is lacking preservation detail, making it difficult to give an accurate species identification. However, based on size and abundance, it's very likely to be from Triceratops horridus.
It comes with a metal display stand.

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.
