Pachycephalosaurus Fibula

Pachycephalosaurus wyomingensis Fibula 

Own an exceptional piece of prehistoric history with this authentic Pachycephalosaurus wyomingensis fibula fossil from the world-famous Hell Creek Formation of southeastern Montana. Dating to the Late Cretaceous Period approximately 66 million years ago, this remarkable specimen was discovered in a rural area of Carter County, Montana.

This complete fibula measures approximately 12 inches long and is preserved in remarkable condition. The specimen displays beautiful natural fossil texture and coloration with minimal restoration present. Only minor crack fill has been applied for stabilization, while the bone remains otherwise highly complete and authentic.

The fibula is a long, slender bone of the lower hind limb. While Pachycephalosaurus is best known for its distinctive thick, domed skull, postcranial material representing other parts of the skeleton offers a fascinating look at the anatomy of this unusual Late Cretaceous dinosaur.

This exceptional specimen is presented on the custom-built display stand pictured, featuring a substantial 6 × 14 × 2-inch wooden base designed to complement and support the fossil. With the fibula mounted on the stand, the complete display measures approximately 8 inches tall, creating an impressive museum-style presentation ready for display.

With its impressive size, high degree of completeness, minimal restoration, documented locality, and custom presentation, this specimen makes an outstanding centerpiece for a serious dinosaur fossil collection, museum display, educational collection, or natural history collection.

A detailed provenance portfolio and Certificate of Authenticity will accompany this specimen. Exact discovery coordinates from the southeastern Montana locality will be provided to the buyer within the provenance documentation.

About Pachycephalosaurus wyomingensis

Pachycephalosaurus wyomingensis was a distinctive herbivorous dinosaur that lived in western North America during the final part of the Late Cretaceous Period. It is best known for the massive dome of bone forming the top of its skull, a feature that makes Pachycephalosaurus one of the most recognizable dinosaurs from the Hell Creek ecosystem.

The name Pachycephalosaurus means “thick-headed lizard,” a reference to this extraordinary skull anatomy. The dinosaur was bipedal, walking primarily on two powerful hind limbs, with a relatively lightweight body and long tail.

While the characteristic domed skulls and cranial material of Pachycephalosaurus are particularly recognizable, fossils from elsewhere in the skeleton provide an important look at the overall anatomy of this unusual dinosaur. A fibula such as this formed part of the lower hind limb alongside the larger tibia.

Pachycephalosaurus shared its Late Cretaceous environment with some of North America's most famous dinosaurs, including Tyrannosaurus rex, Triceratops, Edmontosaurus, and Ankylosaurus.

About the Hell Creek Formation

The Hell Creek Formation is one of the most famous fossil-producing formations in the world and is renowned for preserving some of the last non-avian dinosaurs to live before the end-Cretaceous mass extinction event approximately 66 million years ago.

The formation occurs across portions of Montana, North Dakota, South Dakota, and Wyoming and preserves ancient environments that included rivers, floodplains, forests, and coastal lowlands. These ecosystems supported an extraordinary diversity of prehistoric life.

Fossils recovered from the Hell Creek Formation include Tyrannosaurus rex, Triceratops, Edmontosaurus, Ankylosaurus, Pachycephalosaurus, turtles, crocodilians, fish, mammals, and many other organisms.

Because of its scientific importance and extraordinary fossil record, authentic specimens from the Hell Creek Formation remain highly valued by collectors, educators, museums, and researchers. Fossils accompanied by detailed provenance and documented discovery localities are particularly desirable for serious collections.
