Note: Claims that hybrids can be produced from this highly disparate cross require confirmation.

The following transcript is of an odd story that appeared on page 2, column 3, of the April 12, 1873 issue of the Clarksville Weekly Chronicle, a newspaper published in Clarksville, Tennessee: (Access source): “A strange monstrosity was born on

the farm of Wm. E. Davis, in Mercer county [Tennessee], a week or two ago. It was the offspring of a cotswold ewe and was more like a turtle than anything else. In shape it was nearly round and flat, with a crust on the back. The only wool it had was a small tuft on the back of a small curiously shaped head. The feet set out at the sides like those of a turtle. Mr. Davis can only account for the monstrosity from the fact that the ewe must have been frightened when with lamb by a turtle in the branch which flows through the pasture.

Are turtle-sheep hybrids possible?

The alligator snapping turtle (Macrochelys temminckii), one of the heaviest freshwater turtles in the world, is native to the southeastern U.S., including Tennessee. It reaches weights of at least 300 pounds and so, at least conceivably, would be capable of mating with a sheep. However, the authenticity of this hybrid has never been verified, nor does it seem to have been reported elsewhere.
