35 million years ago in South America sailed two groups of monkeys instead of one

About 35 million years ago South America from Africa migrated not only broad-nosed monkeys, but also relatives of Parajanov, reported in Science. To such conclusion paleontologists from Argentina and the United States. It turns out, this Intercontinental migration was committed by two groups of mammals (rodents from the group Caviomorpha and broad-nosed monkey) and three.

Almost 100 million years (during the period 100-3 million years ago) of South America had no land connections with other continents. However, on this continent found mammals whose closest relatives live in Africa, representatives of protrade Caviomorpha (rodents of the suborder dekoratorsky) and Platyrrhini (broad-nosed monkeys). Considering that before the Atlantic ocean was not as wide as it is now, scientists suggest that these animals got to South America on natural rafts of about 35-45 million years ago. Then the distance between it and Africa was 1500-2000 miles.

Earlier in Peru, 7.5 kilometres South from the border with Brazil, on the banks of the river Jurua (region of ucayali) found the remains of the animal, which, presumably, part of the stem-group of new world monkeys (closer to their common ancestor than the existing monkeys of this group). Now paleontologists from several universities of Argentina and the United States headed by Kenneth Campbell, Jr. (Kenneth E. Campbell Jr.) from the Los Angeles Museum of natural history presented the results of new expeditions associated with that area.

Scientists have described four molars (molar) of a previously unknown Primate. The age of the finds is estimated at 32-35 million years. Their owner has assigned the Latin name Ucayalipithecus perdita, the generic name means “monkey of Ucayali”. The molars of kalpitiya compared with the teeth of the extinct new world monkeys Panamacebus transitus and Perupithecus ucayaliensis (last found where Ucayalipithecus), modern three-way broad-nosed monkeys of Gurukula (Aotus trivirgatus), and parafianovich Abuqatrania basiodontos and Qatrania wingi with the territory of modern Egypt and a number of others.
