Authentic Dinosaur Limb Bone Fragment (Late Cretaceous, Lance Formation) Specimen Type: Dinosaur Metapodial or Long Bone Shaft Fragment. Formation: Lance Formation Age: ~66–69 Million Years Ago Location: Lance Creek, Niobrara County, Wyoming, USA Dinosaur Group: Likely Hadrosaurid or Ceratopsian This exceptional fossil specimen is a dense, well-preserved dinosaur limb bone fragment, discovered in the iconic Lance Formation of eastern Wyoming — a paleontological treasure trove known for yielding fossils of Tyrannosaurus rex, Edmontosaurus, and Triceratops horridus. The fossil exhibits the classic characteristics of a cortical bone section, with a rounded, smoothed profile formed from natural erosion over millions of years, likely due to fluvial transport or weathering within the Lance paleo-river systems. Its robust structure and coloration suggest it originated from a metapodial (toe or foot bone) or a distal long bone shaft, where compact bone density is at its highest.
