    Dinosaur Bone Fragment vs Bison Antiquus Bone in Idaho: Field Identification

    Ancient mammal bone and dinosaur bone separate through geologic context as much as surface texture. The fastest separation comes from the visible field marks you can confirm before you pocket or collect anything. Idaho context matters because Dinosaur Bone Fragment is a realistic Idaho fossil profile built around mineralized cortical bone from large terrestrial vertebrates in badlands.
