As far as I know, no fossil ape species has yet been found which managed this. Human infants are sometimes born with a small tail, but this is just a vestige of the embryonic tail not disappearing correctly, it is not a true, bony tail. Imagine one day finding a true tailed ape fossil and it getting the name Wukongia or Saiyania! submitted by /u/yushaleth [link] [comments]
