This is a museum quality replica Seventy million years ago, a hulking T. rex chomped into a fresh carcass. As the giant meat-eater's teeth ripped flesh from bone, this large tooth broke loose and fell to the ground to be fossilized and then cast millions of years later.

T. rex commonly lost teeth like this one in a process we call "shedding." These teeth are usually found by scientists apart from a full T. rex skeleton, often near a plant eating dinosaur carcass that served as a feast for the giant Cretaceous predator.

Specs: Tyrannosaurus rex.
Late Cretaceous (70 m.y.a.). North America. Real Trex teeth can cost $1000 per inch. This tooth was cast directly from the actual tooth and painted to look like the original tooth.
