We can say that this fossil is more similar to the living Cercopithecinae.
We can arrive at this answer because:
- The live Cercopithecinae were large primates that fed primarily on vegetables, including grasses and roots, although they also fed on fruits and flowers, they were terrestrial quadrupeds and had two premolars.
- These characteristics can be seen in Theropithecus, showing that the two animals have genetic, structural, and adaptive similarities, which indicates some kind of genetic kinship.
The number of common characteristics between Theropithecus and the Cercopithecinae are many, which may explain the similarities between their fossils.
