[39] The data do not fully represent the actual overall number of deaths of the Amazon river dolphins, whether accidental or intentional, because a variety of factors make it ...
Its fossils were discovered near Piña, Panama. [15] [16] River dolphin has been considered a taxonomic description, suggesting an evolutionary relationship among the group, although it is now known that they form two distinct clades. 'True' river dolphins are descendants of ancient evolutionary lineages that evolved in freshwater environments ...
These ancient dolphins had fins, razor sharp teeth, and they were big! Researchers at the University of Zurich estimated that the 16-million-year-old fossil was more than 11 feet long and is said ...
South Asian river dolphins are toothed whales in the genus Platanista, which inhabit the waterways of the Indian subcontinent. They were historically considered to be one species (P. gangetica) with the Ganges river dolphin and the Indus river dolphin being subspecies (P. g. gangetica and P. g. minor respectively). Genetic and morphological ...
A newly identified ancient skull found in Peru has revealed an extinct giant called Pebanista yacuruna that offers insight into the evolution of freshwater dolphins.
Researchers with NOAA and the University of Miami, among others, worked for eight years studying 147 skulls and 43 spines of stranded bottlenose dolphins. Some specimens were found in South ...
