Description

This incredibly preserved Triceratops squamosal comes from the Lance Formation near Newcastle, Wyoming, and still carries its epoccipitals, the bony scallops that lined the outer edge of the frill.

It will come with a laser etched anodized metal identification card with all information.

It measures 18 1/4" wide and 12 3/4" tall. On the stand it is 18 1/2" tall. The base of the stand is 16" x 8".

Absolutely no restoration.

Just stabilized the cracks and reattached a portion near the bottom (closest to the base)

Collected by us in 2025 near Newcastle, WY.

The squamosal is one of the paired bones that formed the sides of the Triceratops frill, extending back from behind the brow horns to meet the parietal at the rear of the skull. Epoccipitals began as separate bones and fused to the frill as the animal grew and a squamosal with them still attached shows the frill edge as it looked in life.

The Lance Formation preserves some of the last dinosaurs of the Late Cretaceous, roughly 66 to 68 million years ago, and Triceratops is its best known resident.

This is a strong display piece for collectors who want an identifiable section of the most famous horned dinosaur skull.

The Triceratops, lived during the Late Cretaceous period, approximately 68 to 66 million years ago. This herbivorous species is distinguished by its large body, strong legs, and three prominent facial horns - one on the nose and one above each eye. The most striking feature of Triceratops is its large skull, which includes a solid frill at the back. This frill, combined with the horns, was likely used for defense against predators, such as Tyrannosaurus rex , as well as for display and species recognition among other Triceratops. Fossil evidence indicates that these dinosaurs could grow up to 30 feet in length and weigh between 6 to 12 tons. Their teeth were arranged in groups that formed a constantly replaced battery, ideal for their diet of fibrous plants. Triceratops fossils are among the most abundant for any dinosaur, making it a key species for understanding the Late Cretaceous period.
