Incredible Fossil Found an Ancient Four-Legged Snake

Najash Rionegrina Fossil History found a very rare and unique snake, which got published in the Science Advances journal. This is a fantastic study, which saw a snake with rear limbs. This new study helps to clear many doubts about how the snakes lost their rear arms and developed this distinctive skull. This fossil is 70 million years old. The flexibility of the snakes’ neck is evolved from lizard ancestors. The flexibility of the snake body is fascinated by the ability of the body’s vertebrate. However, not many fossil records have proved the early evolutions until now.

Dr. Alessandro Palci, from Flinders University, was one of the members of the international research team. He examined high-resolution CT scanning and light microscopy of the protected skull of the Najash to know the valuable new anatomical data of the early formation of snakes. He says that snakes are known as legless creators and some lizards. The difference between snakes and lizards is the mobility of the skull of the snake. There are no proven facts for the transition of the snake’s skull mobility from the rigid head. This highly flexible snake’s head allows them to swallow large items.

Najash is a 95 million old snake. It is a complete and three-dimensional snake. This skull will provide many unknown facts of how the head of the snake evolved. Some plastic parts are found but not like the current snakes. Its middle ear is a transition between the lizard and the living snake. It has well-developed cheekbones, unlike modern snakes. This feature again resembles the lizard. Najash is not an aquatic snake; it lives in deserts. Snake evaluation scholars are guessing the looks of these ancient animals. Mike Lee, Flinders University, and South Australian Museum researcher Professor was a part of this research. He says that Najash reveals how the snakes are descriptively evolved from lizards. This is like a Darwin project.
