Welcome to Pioneer Fossils!

A Certificate of Authenticity with a color photo on it of the exact item listed here, will accompany this specimen. Plus a custom metal stand and a small picture of a Triceratops.

Here is a superb piece of genuine fossil frill bone from a Triceratops, from the late Cretaceous, as late as 66 million years ago, the end of the Reign of Dinosaurs. It measures about 5.4 inches tip to tip (137 mm.).

It not only has some wonderful blood grooves, but it is an edge piece as well. About as nice as they come.

It is from Hell Creek Formation near Newell, South Dakota.

Triceratops is one of the most famous of all dinosaurs, with its huge head, tough bony frill, and three sharp horns in the front. The movie, Jurassic Park, features a sick Triceratops that Ellie cared for.

The largest Triceratops grew to over 28 feet in length, and weighed up to 13 tons. It was, however, a plant-eater, with a beaked jaw and hundreds of teeth (up to 800) packed closely together for chewing the plants. There are two different Triceratops: horridus and prorsus. The horridus are always found in ground below the prorsus, so they are older. The horridus have a smaller nose horn and larger beak than the prorsus.

A very interesting and genuine fossilized piece of a famous species of dinosaur.

The Frill was the huge saucer-shaped group of bones (they look like one big bone) that extended behind the skull of Triceratops and other Ceratopsians. The frill could have been used for defense or possibly to help in mating. The grooves are called blood grooves, where long ago, blood traveled through these passages to provide nourishment to the frill bones.
