Paleosubspecies

The fact is that apart from hominids and the two genera discussed above , fossil histories of paleosubspecies are virtually un known [ Van Valen , 1966 ].

The paleosubspecies had larger dentition than that found in extant orangutans ( Hooijer 1948 ; Morbeck and Zihlman 1988; Smith and Pilbeam 1980) and are thought to have been somewhat larger in body size than either extant subspecies, or of similar body size but more megadont than either extant subspecies (Hooijer 1948; Smith and Pilbeam 1980; Tuttle 1975).

Thus, all fossil material is considered here to represent the living species M. chimachima, but may be recognizable as a large, temporal paleosubspecies, M. chimachima readei.
