Origin: Kentucky, USA
Genus: American bison
Era: Pliocene (2.6 mya)
Description: These bison vertebra are found in the coolest way. I've mined a lot of stone... but none as fun as this. The collectors wander around in marsh and swamp area barefoot. when they feel something solid with their feet, they reach down into the water and pull it up. When they are lucky, its a fossil.
The bones have calcified over the hundreds of thousands of years.
