Other stem catarrhines include propliopithecoids, such as "Aegyptopithecus", and pliopithecoids, such as "Pliopithecus". It is possible that "Propliopithecus" is the same creature as "Aegyptopithecus". The interorbital distance of "Aegyptopithecus zeuxis" is large much like that found in colobines. It is also possible that "Aegyptopithecus" ate hard objects on occasion. "Aegyptopithecus" lived in the Fayum area of northern Egypt. "Aegyptopithecus" is believed to be a stem-catarrhine, a crucial link between Eocene and Miocene fossils.
