This articulated whale molar from the prehistoric Zygorhiza kochii or "yoke root" is rare and of beautiful quality! 

This ancient carnivore roamed the ocean almost 40 million years ago. Although it is assumed it spent its life in the water, Zygorhiza's body had still not completely adapted to the sleek-looking and moving bodies of whales today as its elbows were still able to be flexed. But it did have a long narrow body and a long skull on a short neck. Zygorhiza was a smaller predator--spanning roughly 20 feet--that ate fish and smaller animals, but it was probably prey to larger whales and sharks like Carcharocles angustidens--the ancestor to the great megalodon.
