It is the oldest known colobus monkey and is one of only two extinct species of true colobus monkey described so far, the other species being Colobus freedmani.[3]C. flandrini was larger than its living relatives, estimated at 21 kg (46 lb) in weight.[3]
Fossils of C. flandrini were originally assigned to Macaca by Arambourg before being assigned their current placement by Delson (1973).[4]
