Ancient crocodiles swam from Africa to Spain and lived in the Mediterranean six MILLION years ago. [17] A report published in January 2010 supported this assumption by demonstrating that both Madagascar and Africa were 1,650 km (1,030 mi) south of their present-day positions around 60 mya, placing them in a different ocean gyre and reversing the strong current that presently flows away from Madagascar. [12], To complicate the ancestry puzzle, no terrestrial Eocene or Paleocene fossils have been found on Madagascar,[25][26] and the fossil record from both Africa and Asia around this time is not much better. [17], Because only five terrestrial orders of mammals have made it to the island, each likely to have derived from a single colonization,[30][31] and since these colonizations date to either the early Cenozoic or the early Miocene, the conditions for oceanic dispersal to Madagascar seem to have been better during two separate periods in the past. Lemurs also have furry, pointed ears and long tails, with lemurs often being compared to both monkeys and squirrels. The timing and number of hypothesized colonizations has traditionally hinged on the phylogenetic affinities of the aye-aye, the most basal member of the lemur clade. [12] Furthermore, a fossil strepsirrhine primate from Africa, Plesiopithecus, may suggest that the aye-aye and the rest of the lemurs diverged in Africa, which would require at least two colonization events. [23] However, the 2003 discovery of fossil lorisoids at the Fayum Depression in Egypt pushed the date of lorisoid divergence back to the Eocene, matching the divergence dates predicted by Yoder and Horvath. Scientific evidence suggests that lemurs’ ancestors hitched a ride from Africa to Madagascar across the Indian Ocean on rafts of floating vegetation about 65 million years ago. The fourth-largest island in the world, after Greenland, New Guinea, and Borneo, Madagascar split off from the African mainland about 160 million years ago, during the late Jurassic period, and then from the Indian subcontinent anywhere from 100 to 80 million years ago, during the middle to late Cretaceous period. [49][56] A couple of species once thought to have gone extinct have since been rediscovered. Adalatherium likely disappeared along with the rest of the strange animals on Madagascar 66 million years ago, before the island population began anew with native species like lemurs. And while this generally lines up with what Sclater had once claimed, the new evidence puts the notion of an ancient race of Lemurians that evolved into lemurs to rest. Ancient crocodiles from Africa swam across the Mediterranean to live in Spanish coastal waters, a new study claims. One of the oldest known strepsirrhines, Djebelemur, dates from the early Eocene of northern Africa and lacks a fully differentiated toothcomb. in 2008. [27] The oldest lemur fossils on Madagascar are actually subfossils dating to the Late Pleistocene.

The center of the island, the Hauts-Plateaux, was converted by early settlers to rice paddies and grassland through slash-and-burn agriculture, known locally as tavy. [16][41], The ancestral lemur that colonized Madagascar is thought to have been small and nocturnal. Although all studies place Cheirogaleidae and Lepilemuridae as a sister clade to Indriidae and Lemuridae, some suggest that Cheirogaleidae and Lepilemuridae diverged first,[43][46] while others suggest that Indriidae and Lemuridae were the first to branch off.
