Tyrannosaurus rex Tooth, small Pachycephalosaurus 000–780Despite this tooth's small size, it clearly shows the flesh tearing ability of T. rex teeth. Robust and slightly curved for maximum bone crushing, muscle searing power. And look a little closer and you'll see small serrations, tiny ridges on the edge of the tooth for extra cutting ability. This tooth is a great reproduction at a super price! Click the image for a closer look. Specs: Tyrannosaurus rex. Late Cretaceous (70 m. y. a.). North America. Also
