Archaeolemur
''Archaeolemur'' ("ancient lemur" from Ancient Greek From Ancient Greek ἀρχαῖος (arkhaîos), "Ancient" + Modern Latin lemur, "lemur") is an extinct genus of subfossil lemurs known from the Holocene epoch of Madagascar. ''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. It was larger than any extant lemur, with a body mass of approximately , and is commonly reconstructed as the most frugivorous and terrestrial of the fossil Malagasy primates. Colloquially known as a "monkey lemur," ''Archaeolemur'' has often been compared with anthropoids, specifically the cercopithecines, due to various morphological convergences. In fact, it was even misidentified as a monkey when remains were first discovered. Following human arrival to Madagascar just over 2000 years ago, many of the island’s megafauna went extinct, including the giant lemurs. Radiocarbon dating indi ...

Subfossil Lemur
Subfossil lemurs are lemurs from Madagascar that are represented by recent (subfossil) remains dating from nearly 26,000 years ago to approximately 560 years ago (from the late Pleistocene until the Holocene). They include both extant and extinct species, although the term more frequently refers to the extinct giant lemurs. The diversity of subfossil lemur communities was greater than that of present-day lemur communities, ranging from as high as 20 or more species per location, compared with 10 to 12 species today. Extinct species are estimated to have ranged in size from slightly over to roughly . Even the subfossil remains of living species are larger and more robust than the skeletal remains of modern specimens. The subfossil sites found around most of the island demonstrate that most giant lemurs had wide distributions and that ranges of living species have contracted significantly since the arrival of humans. Despite their size, the giant lemurs shared m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hadropithecus
''Hadropithecus'' ("bulky ape" from Greek ἁδρός (hadros), "bulky, large" + πίθηκος (pithekos), "ape") is a medium-sized, extinct genus of lemur, or strepsirrhine primate, from Madagascar that includes a single species, ''Hadropithecus stenognathus''. Due to its rarity and lack of sufficient skeletal remains, it is one of the least understood of the extinct lemurs. Both it and ''Archaeolemur'' are collectively known as "monkey lemurs" or "baboon lemurs" due to body plans and dentition that suggest a terrestrial lifestyle and a diet similar to that of modern baboons. ''Hadropithecus'' had extended molars and a short, powerful jaw, suggesting that it was both a grazer and a seed predator. The monkey lemurs are considered to be most closely related to the living indriids and the recently extinct sloth lemurs, although recent finds had caused some dispute over a possible closer relation to living lemurids. Genetic tests, however, have reaffirmed the previously presumed r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lemur
Lemurs ( ) (from Latin ''lemures'' – ghosts or spirits) are Strepsirrhini, wet-nosed primates of the Superfamily (biology), superfamily Lemuroidea (), divided into 8 Family (biology), families and consisting of 15 genera and around 100 existing species. They are endemic to the island of Madagascar. Most existing lemurs are small, have a pointed snout, large eyes, and a long tail. They arboreal, chiefly live in trees and nocturnal, are active at night. Lemurs share resemblance with other primates, but evolved independently from monkeys and apes. Due to Madagascar's highly seasonal climate, Evolution of lemurs, lemur evolution has produced a level of species diversity rivaling that of any other primate group. Until shortly after humans arrived on the island around 2,000 years ago, there were lemurs as large as a male gorilla. Most species have been discovered or promoted to full species status since the 1990s; however, lemur Taxonomy (biology), taxonomic classification is ...

Sloth Lemur
The sloth lemurs (Palaeopropithecidae) comprise an extinct family of lemurs that includes four genera. The common name can be misleading, as members of Palaeopropithecidae were not closely related to sloths. This clade has been dubbed the ‘‘sloth lemurs’’ because of remarkable postcranial convergences with South American sloths. Despite postcranial similarities, the hands and feet show significant differences. Sloths possess long, curved claws, while sloth lemurs have short, flat nails on their distal phalanges like most primates. Diet Members of the family Palaeopropithecidae appear to have eaten a mix of fruit, nuts, and foliage. The sloth lemurs were mixed-feeders rather than specialized browsers who ate a mixed diet based on seasonality. On the basis of highly robust mandible, ''Palaeopropithecus'' and ''Archaeoindris'' can be considered highly folivorous. The family Palaeopropithecidae exhibited molar megadonty, small deciduous teeth with low occlusal length ratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strepsirrhini
Strepsirrhini or Strepsirhini (; ) is a Order (biology), suborder of primates that includes the Lemuriformes, lemuriform primates, which consist of the lemurs of Fauna of Madagascar, Madagascar, galagos ("bushbabies") and pottos from Fauna of Africa, Africa, and the lorises from Fauna of India, India and southeast Asia. Collectively they are referred to as strepsirrhines. Also belonging to the suborder are the extinct Adapiformes, adapiform primates which thrived during the Eocene in Europe, North America, and Asia, but disappeared from most of the Northern Hemisphere as the climate cooled. Adapiforms are sometimes referred to as being "lemur-like", although the diversity of both lemurs and adapiforms does not support this comparison. Strepsirrhines are defined by their "wet" (moist) rhinarium (the tip of the snout) – hence the colloquial but inaccurate term "wet-nosed" – similar to the rhinaria of canines and felines. They also have a smaller brain than comparably sized sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primate
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large bra ...

Daubentoniidae
''Daubentonia'' is the sole genus of the Daubentoniidae, a family of lemuroid primate native to much of Madagascar. The aye-aye ''(Daubentonia madagascariensis)'' is the only extant member. However, a second species known as the giant aye-aye The giant aye-aye (''Daubentonia robusta'') is an extinct relative of the aye-aye, the only other species in the genus ''Daubentonia''. It lived in Madagascar, appears to have disappeared less than 1,000 years ago, is entirely unknown in life, an ... ''(Daubentonia robusta)'' lived until recently, becoming extinct within the last 1000 years.

Cheirogaleidae
The Cheirogaleidae are the family of strepsirrhine primates containing the various dwarf and mouse lemurs. Like all other lemurs, cheirogaleids live exclusively on the island of Madagascar. Characteristics Cheirogaleids are smaller than the other lemurs and, in fact, they are the smallest primates. They have soft, long fur, colored grey-brown to reddish on top, with a generally brighter underbelly. Typically, they have small ears, large, close-set eyes, and long hind legs. Like all strepsirrhines, they have fine claws at the second toe of the hind legs. They grow to a size of only 13 to 28 cm, with a tail that is very long, sometimes up to one and a half times as long as the body. They weigh no more than 500 grams, with some species weighing as little as 60 grams. Dwarf and mouse lemurs are nocturnal and arboreal. They are excellent climbers and can also jump far, using their long tails for balance. When on the ground (a rare occurrence), they move by hopping on t ...
