A 16 million year old fossilized skull of a river dolphin has been found in Peru, South America. Notably, according to scientists, its closest relative is the South Asian river dolphin in the Ganges River of India. Scientific discoveries are considered important. And dolphin paleontologist Rodolfo Salas said the skull belonged to the largest dolphin in South American waters. It is believed that the length of the dolphin was 3 to 3.5 meters i.e. 9.8 to 11.4 feet. Scientists found the fossils during a private organization's 2018 expedition to the Napo River.
given name
'The dolphin is related to the Ganges river dolphin in India,' says dolphin palaeontologist Rodolfo Salas. He said the dolphins found in Peru are much larger than their relatives in Asia. According to paleontologists, the ancestors of both dolphins previously lived in the sea. The dolphin is named Pabanista Yacuruna, inspired by the deep-water Peruvian mythological creature Yacuruna.
a species that has become extinct over time
Rodolfo said, 'River dolphins used to live in freshwater environments in both the Amazon and India, but over time this species of dolphin became extinct in the Amazon, but it still survives in India.' It is also worth noting that many river dolphins, called boto, are still found in the Amazon and Orinoco river basins.
