You may have heard many times before that snakes had legs in olden times. Many people have different views on this matter, but at present researchers have called this fact a reality. They have said that ancient snakes also had legs and had chikbones (bones on face). Researchers reported that this creature from the reptile class was a descendant of the ancient lizards, but the flexibility of the snakes' skull is astonishing. How this flexibility came is not yet much information about it.

Researchers have studied the fossils of the ancient creature 'Najus rongirina' of the reptile class. He told that 100 million years ago, the ancestors of snakes had legs and chickbones. These features became completely extinct in modern snakes. This study has been published in the journal 'Science Advances'. Researchers at the University of Alberta, Canada have described how the lizard's ancestors developed a flexible skull of an ancient snake.

In his statement, Alessandro Palaci of Flinders University in Australia said that 100 million years old fossils of snakes were found in North Patagonia, South America. The fossil of Najus rongirina found here was the most preserved fossil till now. Its skull was protected from three sides. Due to this fossil, very important information has been received about the sequence of development of snakes. Also, it came to know how the flexible skull developed in snakes. Told that the shape of the head of Najas was a link between the head of snakes from the ancient lizard.
