This artifact comes from a large fossil cluster which often holds dozens of small bones. This tiny, fossilized bone from a small tetrapod was found in the Richards Spur Quarry near Lawton, Oklahoma. Many of these fossils come from Captorhinus, a reptile that was common in the Permian deposit and estimated to be 486 million years old. These creatures had hooked snouts with extended front teeth and resembled a modern foot long lizard. They were one of the smallest carnivores of their time.
