    Unexpected Step: Snake Ancestor Had Four Feet

    Livescience has a story about the oldest snake fossil.  It doesn’t look too different from a modern snake, except…  it has four legs!  Named Tetrapodophis amplectus (literally, four-legged snake), it lived about 120 million years ago in what is now Brazil.  The fossil was discovered in an exhibit of specimens from the Crato Formation by David Martill, a professor of paleobiology at the University of Portsmouth in the United Kingdom.  The original paper appeared in the jounal Science.
