85-million-year-old snake fossil uncovers reptile history
Two excavations in southeastern Brazil have revealed a well-preserved fossil of a snake species called Tamiara merim, which lived approximately 75 to 85 million years ago during the Cretaceous period. The study indicates that these snakes thrived in a lush environment, and the fossil shows part of the skull that allows reconstruction of its brain anatomy, revealing that it likely led a burrowing or tunnel-dwelling lifestyle. The findings suggest that snakes appeared around 170 million years ago during the Jurassic period, and their emergence and the development of their nervous systems remain some of the most intriguing mysteries in vertebrate evolution, with rare fossils from the Cretaceous highlighting their early adaptations.
