binomial_authority =G. Grandider ,1899 "Palaeopropithecus ingens" is an
extinct lemur that was found onMadagascar and has gone extinct fairly recently. Newradiocarbon dates indicate that "Palaeopropithecus ingens" may have still been living around1500 AD .Morphology
This species had a dental formula of 2:1:2:3 on the upper jaw and 2:0:2:3 on the lower jaw. "Palaeopropithecus ingens" had lower
incisors which were small and vertical and the lower incisors of this species were spatulate. Themolars of this species were narrow and had well-developed shearing crests (Fleagle, 1988). "Palaeopropithecus ingens" had a relatively robust skull and a relatively longsnout as compared to extinctindriids . A mandibular symphysis was present and "Palaeopropithecus ingens" had atubular meatus which extended laterally from the tympanic ring which also differs from extinct indriids. Theforelimbs were longer than thehindlimbs which is in opposition to extinct indriids which had long hind limbs. On the manus thepollex was short and the phalanges were long and curved and "Palaeopropithecus ingens" had anintermembral index of 138.Diet
Due to "Palaeopropithecus ingens"'s
dental morphology this was afolivorous species .Locomotion
"Palaeopropithecus ingens" was a terrestrial quadruped, based upon postcranial remains.
