Protosiren fraasi Variant:Unprimed indicando buena agudeza visualProtosiren fraasi was one of the earliest marine mammals in the sirenian group, ancestors of modern manatees and dugongs. It lived during the Middle Eocene , approximately 40 million years ago, and its fossils have been found in regions of North Africa and the Middle East, including Egypt and Pakistan. This genus represents a key intermediate stage in sirenian evolution, when these animals were transitioning from a semi aquatic to a fully marine life.
