Evolution of lemurs - Wikipedia
Lemurs are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with lorises, pottos, and galagos (lorisoids). Fossils from Africa and some tests of nuclear DNA suggest that lemurs made their way to Madagascar between 40 and 52 mya.
Why Duke University's Lemur Center Travels To Wyoming Every …
2024年12月1日 · Scientists from the Duke Lemur Center at Duke University come out to Wyoming every summer to find fossils from the earliest ancestors of modern-day lemurs and primates. They say the Bridger Basin is the Madagascar of the Eocene Period.
Primate - Evolution, Adaptations, Behavior | Britannica
2024年12月13日 · The known fossil families of the Eocene Epoch (56 million to 33.9 million years ago) include the Tarsiidae (tarsiers), the Adapidae (which include probable ancestors of lemurs and lorises), and the Omomyidae (which include possible ancestors of the monkeys and apes).
The Ancient Primates of West Texas Resembled Lemurs
2023年11月21日 · The species resembled lemurs found in Madagascar today. But these beady-eyed early primates weren’t actually related. In the early Eocene Epoch, omomyids tended to be small with diets of insects and fruits, and they also tended to be nocturnal, says Kirk.
70 Million Years of Primate Evolution - ThoughtCo
2019年11月8日 · During the Eocene epoch — from about 55 million to 35 million years ago — small, lemur-like primates haunted woodlands the world over, though the fossil evidence is frustratingly sparse. The most important of these creatures was Notharctus, which had a telling mix of simian traits: a flat face with forward-facing eyes, flexible hands that ...
Convergent evolution of anthropoid-like adaptations in Eocene
2009年10月22日 · Adapiforms are commonly referred to as the ‘lemur-like’ primates of the Eocene epoch, and recent phylogenetic analyses have placed adapiforms as stem members of Strepsirrhini 2, 3,...

2020年8月8日 · The fossil evidence is compelling and it suggests that there may have been very few lemur species on Madagascar near the end of the Eocene (prior to the initial radiation of Lemuriformes). This is certainly consistent with results that …
Fossil Research - Duke Lemur Center
DFP research is focused on extinction of subfossil mega- and micro-fauna, documentation of evolving habitats across space and time, functional studies of extinct giant lemurs, and ancient DNA and isotopic analyses of extinct as well as subfossil representative of extant species – all aimed at understanding the dynamic changes that have ...
2 New Species of Ancient Primates Identified That Resembled Lemurs
2023年9月21日 · Omomyids initially had body masses below 500 grams, but some evolved to double that size during the late middle Eocene. The two new species identified — from the genera Ourayia and Mytonius — are on the larger end of the spectrum. They probably resembled present-day small to medium-size lemurs and consumed a diet of fruit and leaves.
