The Hindu
They found a fossil in Argentina of a two legged snake. It is thought that snakes evoluted from lizards. The fossil is from 90 million years ago and is under three feet long. Before, they did not know if snakes had their beginning on land or in the water. The fossil they found was the first known snake fossil with a sacrum bone in the hips. The anatomy is evidence that the snake lived on land or in burrows underground instead of in a marine environoment. The fossil shows that the legs were not strong enough for walking, but one of the legs was hurt during the snake's life, suggesting that the legs were actually used. The use is still unclear. A use suggested was bracing for attacks on prey.
