Tyrannosaurus rex Hand Claw, Lance Formation - 6.05 in.

A highly complete Tyrannosaurus rex hand claw is a rare and scientifically significant find, offering an exceptional look at the anatomy and adaptations of this apex predator. Approximately 80% complete by mass and retaining its sharp, intact tip—a feature seldom preserved—this claw provides a glimpse into how T. rex may have gripped prey like Edmontosaurus or Triceratops, or defended itself in the dynamic ecosystems of the Late Cretaceous.

This specimen comes from the Lance Formation in Weston County, Wyoming, a fossil-rich floodplain environment dating back 66 million years. The Lance Formation supported a diverse range of prehistoric life, including iconic dinosaurs such as Triceratops, Ankylosaurus, and smaller theropods like Dakotaraptor. The unique conditions of this ancient floodplain, with its fine-grained sediments and oxygen-poor burial environments, created the perfect setting for fossil preservation.

With its rare intact tip, striking completeness, and historical significance, this claw is not only a scientific treasure but also a striking centerpiece for any serious collection. It captures both the power of T. rex and the story of the ancient world it dominated.
