Hisstory of snakes

A fascinating new fossil find shows that snakes almost certainly evolved on land. A 113 million year old fossil (the most primitive of any snake) from Brasil shows a snake with four tiny limbs and adaptations for burrowing and not swimming. The limbs themselves are probably not big enough or powerful enough for walking but may have assisted in grasping prey or mating. The fossil also exhibited many features that clearly marked it as the ancestor of modern snakes such as hooked teeth, flexible jaws and a flexible spine, the legs themselves were also not vestigial, showing some degree of specialization. Another classic "missing link" species and an amazing find alongside other famous transitional fossils like Archaeopteryx,  Tiktaalik and Ambulocetus to name but a few.
