       Like with Pliopithecus,‭ ‬the genus after which it was named,‭ ‬Propliopithecus was a gibbon-like ape that lived in Northeast Africa during the early Oligocene‭ (‬back in this time Egypt had an extensive covering of vegetation unlike the arid desert conditions that we know today‭)‬.‭ ‬Propliopithecus would have lived in the tree canopy where its stereoscopic vision‭ (‬granted by both eyes facing forwards‭) ‬would have allowed it to travel and reach and across for food with ease.‭ ‬The teeth which have a light enamel covering are most suited to a diet of fruits that would not require strong teeth or jaws to process.
       There is speculation that another primate called Aegyptopithecus is actually the same as Propliopithecus.‭ ‬Both are known from the same Formation of Egypt,‭ ‬from the same time period and both are similar in form,‭ ‬yet‭ ‬there is no universally accepted decision‭ ‬about whether they are the same or not.‭ ‬Should a decision be made that confirms they are the same‭; ‬Aegyptopithecus will become another synonym to Propliopithecus since this genus was named several decades before Aegyptopithecus.
