What was the country during the Paleocen Epoch?
Paleocene epoch is the time on Earth between chalk, 65.5 million years ago, up to 55.8 million years ago. paleocene means "old (er) new" in Greek. This is the reference to the fact that Paleocene was the beginning of the mammal era that continues today, but was too primitive to contain modern animal orders.
During the paleocene, the climate was rather similar to the mesozoic (age of dinosaurs) - warm and wet, with tropics extending to at least 45 degrees from the equator and mild forests reaching poles. Large areas of Central Eurasia, North America and Southeast Asia were flooded. Antarctica was a slight continent with a fauna warning, an ever -associated Antarctic Peninsula with South America. This closed Drake's passage and prevented the formation of Antarctic Cirumpolar current, which would cause Antarctica to freeze the solid about 22 million years after the end of the era.
At the very beginning of the paleocene, a lot of life was destroyed when an asteroid 6 miles (10 km) killed into what DN isES on the Yucatan Peninsula in Mexico. This kicked a cloud of dust that covered the Earth for at least a few years, killing most of the plants addicted to photosynthesis and animals that require to live. The largest animals - dinosaurs - were all smoothed, along with pterosaurs (flying plasimi), balls, pliosaurs, mosasaur (water reptiles) and many plants and invertebrates. This has left an open huge range of niches to be used by primary surviving groups - birds and mammals.
Most mammals in the paleocene were relatively small - below 20 kg (44 lb). The time of leisure starts as small mammals similar to rodents, up to 10 million years have been diversified into several new orders, most of which are now extinct. Xenartha, a mammal, is known to have branched from the rest of the placental mammals about 60 million years ago in the inclusion of ants, sloths on the tree and Armadillos. Marsupials and placentals differed well before the beginning of the period, up to 130 million years ago. For a short timeE before the paleocene created ancestors forms of most live commands-including copier, insects, lakes similar to omnipotent, etc.
even and odd new hooves differ near the beginning of the paleocene. The grass has so far begun to cover Earth, most of the planet is covered with tropical and mild forests instead. As such, most of the mammals were arboreal. At that time, South America, Antarctica and Australia were separated from the rest of the world land mass and dominated the warning rather than a placental fauna. During the Paleocene, few are known about animals living in Antarctica and Australia - it is known to be placental, descendants of mesozoic mammals on every contact (whose fossils are rare) and at least some of them were the forerunners of contemporary Australian and South American maules. Phorusrhacids, "Terror Birds" evolved at the beginning of Paleocen in South America, and (probably) also lived in Antarctica and served as predators of the peak. Marsupial or Clazing Fauna at the time (except crocodiles) was the oppressionAna with these bird killer.
among the groups of placental mammals who benefited in Africa, North America and Eurasia during this period are primates, pleziadapids (rodents similar to primates) and condylarths (ancestors of all neglates). The mammalism of Afrothia, Laurasiatheria and the Euarchontoglres were divided about 20 million years before the beginning of the PaleoCen, so evolution during the PaleoCen was another diversification of these orders, the first available diversification after extinction after the extinction.
