In other news, being of two minds is apparently not new:

"A remarkably well-preserved fossil of a two-headed reptile has been discovered in the Early Cretaceous Yixian rock formation in northeast China.

The tiny skeleton of a hatchling choristodere – a group of extinct aquatic reptiles with long necks – has two heads and two necks, fused at their base. The 120-million-year-old specimen is thought to be the oldest example of a developmental anomaly known as axial bifurcation.

While rare, this type of malformation has been seen before in living snakes, crocodiles, lizards and turtles – some of which have survived for several years in captivity.

However, judging from the extreme juvenility of the fossilised skeleton – its proportionally large head and eye orbits – the tiny creature did not survive for long, say its finders Eric Buffetaut at National Centre for Scientific Research in Paris, France, and colleagues."
