This is an authentic vertebra of Pachycephalosaurus wyomingensis, one of the most famous dome-headed dinosaurs of the Late Cretaceous. Known for its remarkably thick, bony skull dome (likely used for display or head-butting behavior), this unusual herbivore had a robust body, powerful limbs, and a diet consisting of tough vegetation. These dinosaurs roamed what is now North America during the final stages of the Cretaceous period (~68-66 million years ago), sharing the landscape with Triceratops, Tyrannosaurus rex, and other iconic species right up to the mass extinction event.

Sourced from the renowned Hell Creek Formation in Montana, this fossil comes from ancient floodplain and river environments that once teemed with diverse Late Cretaceous fauna.

Specimen Highlights:

• Type: Authentic vertebra from a Pachycephalosaurus - a solid section from the backbone of this dome-headed dinosaur, showcasing the natural bone texture, neural canal, and robust architecture typical of these Late Cretaceous herbivores
• Dimensions: 2.75 inches wide.
• Color & Preservation: Natural tan to dark brown mineralization typical of Hell Creek fossils, with a rich patina and good surface detail.
• Condition: Well-preserved solid fragment with restoration performed only on repaired cracks.
• Provenance: Hell Creek Formation, Late Cretaceous, Powderville Montana area (legally sourced from private land).
• Authenticity Guarantee: 100% genuine dinosaur fossil - personally acquired from a trusted paleontologist who collects in the Hell Creek Formation.
• Display: comes with a custom display stand.
• Bonus: Includes a custom fossil description card with Pachycephalosaurus facts, geological context, and a human size reference to help visualize the scale of these animals (adults reached approximately 15 feet long and weighed up to 1,000 pounds or more).

This compact yet striking 2.75-inch vertebra offers a tangible connection to the skeletal structure of Pachycephalosaurus — imagine holding a piece of the backbone that once supported one of the most unique and fascinating dinosaurs of the Age of Reptiles.

Ideal for paleontology collections, natural history displays, educational classrooms, cabinets of curiosity, or as a unique gift for dinosaur lovers and fossil enthusiasts.
