19.3" Fossil Triceratops Brow Horn - Montana
This is a really cool, fossil Triceratops brow horn collected from the Late Cretaceous Hell Creek Formation in Montana, making it approximately 66 million years old. This is one of the two horns that sat above the eye sockets, and would have protruded outward anteriorly from the skull of the dinosaur. Multiple preserved blood/nerve canals (a.k.a. "blood grooves") can be found around the exterior of the horn.
It measures 19.3" long, with a measurement of 6.7" wide at its base. On the included, custom metal display stand it stands 18.9" tall.
Overall the bone preservation is excellent! There is significant gap fill restoration through the first 7" (from the top) of the horn. The remaining 12.3" of the horn has minimal gap fill restoration, primarily along the proximal end. In total, restoration makes up approximately 8-10% of the specimen.

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.

The Hell Creek Formation
Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
