A species of ancient snake had hind limbs for around 70 million years before losing them, scientists have discovered. This shows these creatures lived successfully with legs for a very long time before developing the characteristic body shape seen today—adding to the complicated story of snake evolution.
Scientists are busy investigating fossils from over 95 million years ago that show an ancient snake with legs that looked somewhat like a lizard. This creature is called Eupodophis descouensi and lived in what is now Lebanon. Over many millennia these ancient “snakes” evolved into today’s legless reptiles.
