Rare 13-million-year-old fossil represents a new species
A 13-million-year-old infant’s skull, discovered in Africa in 2014, comes from a new species of ape that may not be far removed from the common ancestor of living apes and humans.
The tiny find, about the size of a lemon, is one of the most complete skulls known of any extinct ape that inhabited Africa, Asia or Europe between 25 million and 5 million years ago, researchers report in the Aug. 10 Nature. The fossil provides the most detailed look to date at a member of a line of African primates that are now candidates for central players in the evolution of present-day apes and humans.
Most fossils from more than 40 known extinct ape species amount to no more than jaw fragments or a few isolated teeth. A local fossil hunter spotted the nearly complete skull in rock layers located near Kenya’s Lake Turkana. Members of a team led by paleoanthropologist Isaiah Nengo estimated the
