85M-year-old snake fossil uncovers reptile history
A well-preserved fossil of a snake from southeastern Brazil, dating back approximately 75-85 million years during the Cretaceous period, has been discovered. It is among the rare specimens that contain detailed features, especially in the skull, allowing for a deeper understanding of snake evolution. The study showed that this species lived inside burrows or tunnels, similar to current snakes such as the coral snake. This finding enhances our understanding of the origin and development of snakes, which appeared around 170 million years ago during the Jurassic period. The fossil reflects an early development of the nervous system that was not possible to observe before. These discoveries are important for comprehensively understanding snake evolution, especially given the scarcity of well-preserved fossils from the dinosaur era.
