Two-Headed Reptile Fossil From Age of Dinosaurs Found:
Palaeontologists have found a tiny dinosaur-era reptile with two heads—the first time the extremely rare developmental anomaly has been found in a fossil. The 120-million-year-old specimen, just 2.8 inches (7 centimeters) long, is a hatchling of a species of Choristodere—extinct aquatic reptiles resembling modern-day crocodiles or lizards.
