Scientists found a fossil of a two-headed reptile:
This animal was a choristoderan, an extinct reptile that reached a length of one metre in adulthood and was characterised by a long neck - two in this case.
The animal's spinal column divided in two at the point where the neck emerges from the body. This formed two long necks that ended in two skulls.
Almost like the hydra encountered by Hercules!
