Tyrannosaurus rex Foot Claw - 6.05"

A Rare Glimpse into Tyrannosaur Anatomy

This highly complete Tyrannosaurus rex foot claw is both rare and scientifically significant, offering a clear window into the anatomy and adaptations of one of prehistory’s most iconic apex predators. Retaining its original tip—a feature seldom preserved in fossilized claws—it stands out as an exceptional example of T. rex morphology.

Discovered in the Lance Formation of Weston County, Wyoming, the claw dates to the Late Cretaceous, about 66 million years ago. This fossil-rich floodplain, known for its fine-grained sediments and oxygen-poor burial conditions, has produced a diverse array of species including Triceratops, Ankylosaurus, and Dakotaraptor.

For T. rex, robust foot claws played a critical role in locomotion—providing traction, balance, and support during movement and predation. The remarkable completeness of this specimen, including the rare intact tip, offers valuable anatomical insights and enhances its visual and scientific appeal.

Whether displayed in a research setting or a curated private collection, this claw captures the strength and adaptability of the ancient world it once belonged to. Its preservation and provenance make it a compelling centerpiece with both academic and aesthetic value.
