Indriidae [SEP] parent taxon
Indriidae
The Indriidae (sometimes incorrectly spelled Indridae) are a family of strepsirrhine primates. They are medium- to large-sized lemurs, with only four teeth in the toothcomb instead of the usual six. Indriids, like all lemurs, live exclusively on the island of Madagascar.
Characteristics.
The 10 extant Indriidae species vary considerably in size. Not counting the length of their tails, the avahis are only in length, while the indri is the largest extant strepsirrhine. The tail of the indri is only a stub
Traits of the postcranium (skeleton below the skull) indicate that "Babakotia" was the next most closely related sloth lemur to "Archaeoindris" and "Palaeopropithecus", followed by "Mesopropithecus", the smallest of the sloth lemurs.
All four genera of sloth lemurs are known to be a sister taxon (close relatives) of family Indriidae, which includes the indri ("Indri"), sifakas ("Propithecus"), and woolly lemurs ("Avahi"). This relationship is supported by data from
