Late Miocene phalanges from Hungary have also been assigned to this genus, but were later reclassified as Dryopithecus.

[1] Rangwapithecus weighed approximately 15 kg (33 lb) and the size and shape of the ape's teeth indicate that it was a folivore.

[2] An arboreal ape from the earliest Miocene[3] adapted to life in the rainforest, it is associated particularly with Mfangano Island[4] although the species previously inhabited a woodland-bushland environment.

[8] Rangwapithecus gordoni and P. africanus are similarly sized though they differ morphologically, and both are restricted to Koru and Songhur.

[9] Rangwapithecus was a generalised frugivore that was also able to engage in folivory as a fallback during times of dietary stress.
