Triceratops Frill

A piece of frill from the famous horned dinosaur, Triceratops. It comes from the Hell Creek Formation in Carter County, Montana. This formation was laid down by ancient floodplains in the Late Cretaceous and preserves fossils of Triceratops and Tyrannosaurus, as well as many other well known dinosaurs. Its top, the K-Pg boundary, marks the asteroid impact that ended the dinosaurs.

This is a nice big section of frill featuring some excellent surface detail. It has a network of branching channels etched across the surface - these vascular grooves housed blood vessels that nourished the skin and keratinous sheath covering the frill during life. There is also a small vascular hole (foramen) where a larger blood vessel would have passed through the bone tissue. The piece features one neat repair but no restoration.

The bone comes with a display stand as pictured and a small card featuring the specimen name, region it was found and age.

This is genuine fossil. All the specimens we offer come with a lifetime authenticity guarantee.
