Snake fossil discovered with legs

While I neither teach Biology, nor is it my primary area of interest, I do love all things science and this is no different. Fossils have been discovered that have found an evolutionary 'missing link' between snakes and other reptiles. The really interesting thing about these fossils is that they HAVE LEGS! The fossil is over a hundred million years old and was discovered in Brazil.

These legs come as no surprise to biologists who have predicted this as a number of species of snakes carry 'spurs' that are vestigial leftovers from legs that have long since evolved away (see image below).
