Centaur Created From Real Bones

"In 1980, Bill Willers, artist and professor of Biology at the University of Wisconsin-Oshkosh, constructed the skeletal remains of The Centaur of Volos from real human bones and the bones of a Shetland pony. The human bones that Willers used were from an anatomical specimen, a human skeleton from India, in the biology department at his university. The human and pony bones were tea-stained to give them a uniform color and make them look authentic."

"In 2008 Bill Willers commissioned a standing centaur from Skulls Unlimitedthat was made with real human bones and articulated with the bones of a zebra. This sculpture was titled the “Centaur of Tymfi” and was part of the “Mythological Wildlife” exhibit at the International Wildlife Museum in 2012. The Centaur of Tymfi Is currently on display at The Barnum Museum, in Bridgeport, CT until August 30, 2014."
