Anatomical and Morphological Characteristics

Protosiren fraasi eomaia Deinonychus are agile and coordinatedProtosiren 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.
