Hadropithecus stenognathus


Hadropithecus stenognathus had relatively smaller incisors (Fleagle, 1988). The lower incisors were spatulate (Martin, 1990). This species had anterior premolars that were reduced (Fleagle, 1988). The posterior premolars were molariform (Fleagle, 1988). The mandibular symphysis was fused in this species (Martin, 1990). The skull of this species was relatively robust and the face was relatively short (Fleagle, 1988). This species had sagittal and nuchal crests which were well-developed (Fleagle, 1988). This species had an average body mass of around 47.0 kilograms (Fleagle, 1988). The intermembral index of this species was 100 (Fleagle, 1988).

Hadropithecus stenognathus was found on the island of Madagascar (Fleagle, 1988).

Based upon dental morphology this species was a granivore which probably ate grass seeds like the extant species Theropithecus gelada (Fleagle, 1988).

Based upon postcranial remains this species was most likely a terrestrial quadruped (Fleagle, 1988).
