Triceratops was one of the last dinosaurs to appear in the Late Cretaceous. Like other members of the Ceratopsid family, these large quadrupeds sported bony frills, horns, and beak-like mouths.

Their frills were theorized to have a number of purposes, ranging from defense, identification, cooling, and mating display. Although the science of their use is not conclusive, the broad frills and horns have made Triceratops one of the most iconic dinosaurs and are immediately recognizable.

These fossils are fragments of Triceratops Frill recovered from private land in the Hell Creek Formation in South Dakota and each dates back over 66 million years to the Cretaceous Period.

Each of these showcase frills is a one of a kind and unique item. They are packaged in a sturdy shipping container and come with a certificate of authenticity.

We also have a selection of Small and Medium sized frill fragments available as well. Check out all our Triceratops Specimens below!

Triceratops was one of the last dinosaurs to appear in the Late Cretaceous. Like other members of the Certatopsid family, these large quadrupeds sported bony frills, horns, and beak-like mouths.

As you might expect, there is evidence that the frill and horns were used as defensive weapons against predators such as Tyrannosaurus Rex, including partially-healed frills and brow horns with Tyrannosaurid tooth marks. However, this is far from settled science.

Assessments of progressive changes in horn orientation and shape during adolescence also indicate the possible visual identification of juveniles, and eventually the onset of sexual maturity. Furthermore, the horns may have been important for mating displays (sexual dimorphism) or even species recognition amid large herds.

In addition, the presence of blood vessels in the frill suggest that these features could be used in identification, courtship, and dominance displays, much like the antlers and horns of modern reindeer, mountain goats, or rhinoceros beetles. The blood vessels also point to the possibility that the frill served to help regular body temperature.

In adulthood, Triceratops measured 29ft long and 10ft tall, with the head comprising nearly one-third of the overall length. These highly evolved herbivores had four dental batteries with which they masticated their food using massive jaw muscles. The dental batteries allowed worn teeth to be continually replaced. Which plants they preferred remains a mystery, but their browse height was probably less than 6ft.
