3.6" Ceratopsid Phalange (Toe Bone) - Judith River
This is a phalange (toe bone) from a ceratopsid found in the Two Medicine Formation of central Montana. The fossil is 3.6" long and nicely preserved. This is the first phalange (first joint), from the fourth toe, of the back, right foot. It is in excellent condition with two repaired cracks.
Within the Two Medicine Formation, there are multiple ceratopsians. A single bone or tooth is not sufficient to differentiate between genera.

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.
