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 ...
The smaller, nocturnal lemurs, such as mouse lemurs, giant mouse lemurs, and dwarf lemurs, usually give birth to more than one infant, whereas the larger, nocturnal lemurs, such as fork-marked lemurs, sportive lemurs, and the aye-aye usually have one offspring. [29] Dwarf and mouse lemurs have up to four offspring, but both average only two.
The indri (/ ˈ ɪ n d r i / ⓘ; Indri indri), also called the babakoto, [8] is one of the largest living lemurs, with a head-body length of about 64–72 cm (25– 28 + 1 ⁄ 2 in) and a weight of between 6 and 9.5 kg (13 and 21 lb).
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 ...
Lemurs were first formally classified in the 10th edition of Systema Naturae.. In the first volume of the 10th edition of Systema Naturae (1758), Carl Linnaeus, the founder of modern binomial nomenclature, created the genus Lemur to include three species: Lemur tardigradus (the red slender loris, now known as Loris tardigradus), Lemur catta (the ring-tailed lemur), and Lemur volans (the ...
The extinction of the largest lemurs is often attributed to predation by humans and possibly habitat destruction. [2] Since all extinct lemurs were not only large (and thus ideal prey species), but also slow-moving (and thus more vulnerable to human predation), their presumably slow-reproducing and low-density populations were least likely to ...
Giant mouse lemurs are vocal, although they also scent mark using saliva, urine, and secretions from the anogenital scent gland. Predators of giant mouse lemurs include the Madagascar buzzard, Madagascar owl, fossa, and the narrow-striped mongoose. Giant mouse lemurs reproduce once a year, with two offspring born after a 90-day gestation ...
