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.
Fossil evidence for the evolution of the toothcomb, a trait shared by lemurs with their closest relatives, the lorisoids, provides insight into both the evolutionary history of strepsirrhines and the lemur colonization of Madagascar. Lemurs were traditionally thought to have evolved during the Eocene (55 to 37 mya) based on the fossil record ...
Archaeolemur is an extinct genus of subfossil lemurs known from the Quaternary of Madagascar. [3] 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.
However, the oldest lemur fossils on Madagascar are actually subfossils dating to the Late Pleistocene. [2] Once part of the supercontinent Gondwana, the island of Madagascar has been isolated since it broke away from eastern Africa (~160 mya), Antarctica (~80–130 mya), and India (~80–90 mya).
Is the Ring-Tailed Lemur Endangered? The ring-tailed lemur is an endangered species. Before people arrived in Madagascar around 2,000 years ago, the island was covered by forests.
Subfossil lemurs are lemurs from Madagascar that are represented by recent 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 ...
Coquerel's sifaka (Propithecus coquereli) is a diurnal, medium-sized lemur of the sifaka genus Propithecus.It is native to northwest Madagascar.Coquerel's sifaka was once considered a subspecies of Verreaux's sifaka but was eventually granted full species status.
The monkey lemurs [3] or baboon lemurs [4] (Archaeolemuridae) are a recently extinct family of lemurs known from skeletal remains from sites on Madagascar dated to 1000 to 3000 years ago. [ 4 ] The monkey lemur family is divided into two genera, Hadropithecus and Archaeolemur , and three species.
