Fossils show anacondas reached colossal size far earlier than thought

A new fossil study reveals that giant anacondas achieved their immense size around 12.4 million years ago, a dimension they have largely maintained ever since. This enduring gigantism was enabled by the stable, abundant wetland ecosystems of the Miocene, offering a consistent food source and ideal habitat for these large predators.
