Ancient Snake Brain Uncovers Evolutionary Surprise
An extraordinary fossilized snake discovered in Brazil, dating back 80 million years, is challenging previous scientific understandings of early snake evolution. This exceptionally well-preserved specimen has allowed for detailed reconstructions of its brain, revealing that ancient snakes were far more varied than previously believed. Researchers have found evidence that one species, *Tametara mirim*, was specifically adapted for a burrowing lifestyle. In contrast, other ancient snake fossils indicate adaptations for life on the surface. Furthermore, some fossil evidence points to snakes that lived in marine environments. By 80 million years ago, snakes were already exploring a wide range of habitats and developing diverse sensory systems.
