Archaeoindris fontoynontii is an extinct giant lemur and the largest primate known to have evolved on Madagascar, comparable in size to a male gorilla.It belonged to a family of extinct lemurs known as "sloth lemurs" (Palaeopropithecidae) and, because of its extremely large size, it has been compared to the ground sloths that once roamed North and South America.
Although only the indriids are alive today and represent only a small percentage of the living lemur species, this clade collectively contained the majority of the extinct giant lemur species. [6] [8] Radiocarbon dating of multiple subfossil specimens shows that the giant subfossil lemurs were present on the island until after human arrival ...
Pachylemur is an extinct, giant lemur most closely related to the ruffed lemurs of genus Varecia.Two species are known, Pachylemur insignis and Pachylemur jullyi, although there is some doubt as to whether or not they may actually be the same species.
Archaeolemur is one of the most common and well-known of the extinct giant lemurs as hundreds of its bones have been discovered in fossil deposits across the island. [ 4 ] [ 5 ] It was larger than any extant lemur, with a body mass of approximately 18.2–26.5 kg (40–58 lb), and is commonly reconstructed as the most frugivorous and ...
Genus Cheirogaleus (dwarf lemurs): ten species; Genus Microcebus (mouse lemurs): twenty-four species; Genus Mirza (giant mouse lemurs): two species; Genus Phaner (fork-marked lemurs): four species; Family Daubentoniidae. Genus Daubentonia (aye-aye): one species; Family Indriidae. Genus Avahi (woolly lemurs): nine species; Genus Indri (indri ...
Like many other species of lemur, indri live in a female dominant society. The dominant female often will displace males to lower branches and poorer feeding grounds, and is typically the one to lead the group during travel. [22] It is common for groups to move 300–700 m daily, with most distance travelled midsummer in search of fruit.
In 1948, paleontologist Charles Lamberton proposed a new sub-genus for the giant ruffed lemurs, Pachylemur, which had previously been placed in the genus Lemur. Since the 1960s, it has been considered its own separate genus, although the two extinct species of giant ruffed lemur have sometimes been grouped under Varecia with their closest ...
Megaladapis, informally known as the koala lemur, [1] [2] is an extinct genus of lemurs belonging to the family Megaladapidae, consisting of three species that once inhabited the island of Madagascar. The largest measured between 1.3 to 1.5 m (4 to 5 ft) in length.
