A malformed embryonic or neonate choristoderan reptile from the Lower Cretaceous Yixian Formation of northeastern China is described. The tiny skeleton exhibits two heads and two necks, with bifurcation at the level of the pectoral girdle. In a fossil, this is the first occurrence of the malformation known as axial bifurcation, which is well known in living reptiles.

I bet the folks at the Lost World Museum in Phoenix, New York would love to have that. They already have a one-eyed kitten, a chupacabras, and a mastodon replica. Oh, and it's run by Creationists.
Clearly a transitional form leading to Ghidra, the 3-headed monster.
