Some things just seem more real when viewed as a skeleton. In this case, Skulls Unlimited of Oklahoma City produced a strikingly real articulated Centaur skeleton by combining a human and a horse. Put one of these on your front lawn and I guarantee every toddler in the neighborhood will run for the hills!
