- Archaeoindris fontoynontii
- Madagascar ()
The largest lemur of all time was Archaeoindris fontoynontii, known only from incomplete fossil remains found in Madagascar’s central highlands, but which suggest a body size near to that of a gorilla, and an estimated weight of 150-250 kg (330-550 lb). Its remains have been dated at 8,245 +/- 215 years B.P. (before present day).
