Scientists found a 16 million-year-old giant freshwater dolphin types in the Amazon, uncovering its unexpected link to South Asian river dolphins and offering insights into the evolutionary characteristics of these creatures. Remarkably, its closest living relatives can be discovered in the river dolphins of South Asia.River dolphins are amongst the rarest contemporary cetaceans, with most extant species critically endangered. The new types, named Pebanista yacuruna after a legendary aquatic people thought to populate the Amazon basin, was discovered in Peruvian Amazonia and is dated to be 16 million years old.Changing landscape drove giant dolphin to extinctionThe new dolphin species belongs to the Platanistoidea, a group of dolphins that were typical in the worlds oceans between 24 and 16 million years earlier. “With this fossil record uncovered in the Amazon, we expected to find close family members of the living Amazon River dolphin– however instead the closest cousins of Pebanista are the South Asian river dolphins (genus Platanista).
