In addition to the eight lemur genera that have gone extinct in Madagascar, another extant genus, Daubentonia, is represented by a larger extinct species, the giant aye-aye (Daubentonia robusta), together with the living aye-aye (D. madagascariensis). The difference in size between the extinct form (approximately 14 kg) and the living species (less than 3 kg) is significant (Jungers et al., 2002), although it is believed that giant aye-ayes probably had a similar diet of nuts and invertebrate larvae (Godfrey et al., 2004a). Postcranial skeletal remains also suggest that subfossil aye-ayes were arboreal quadrupeds and had limited leaping abilities, much the same as their modern relatives. Daubentonia robusta is known to have survived at least until A.D. 891–1027 in southern Madagascar.
