The southern route dispersal is primarily linked to the Initial Upper Paleolithic expansion of modern humans and "ascribed to a population movement with uniform genetic features and material culture" (Ancient East Eurasians), which was the major source for the peopling of the Asia–Pacific region.
When a type locality is listed as the site for a formation with many good outcrops, the site is flagged with a note ([Note 2]). When a particular site of note is listed for an extensive fossil-bearing formation, but that site is somehow atypical, it is also flagged with a note ( [ Note 3 ] ).
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c ...
[4]: 2 There is little time between Homo erectus' apparent arrival in South Caucasus around 1.8 Ma, and its probable arrival in East and Southeast Asia. There is evidence of H. erectus in Yuanmou, China, dating to 1.7 Ma and in Sangiran, on Java, Indonesia, from 1.66 Ma. [19]
Like during the Triassic and Jurassic, Rhode Island's sediments were being eroded away rather than deposited during the ensuing Paleogene and Neogene periods of the Cenozoic era, leaving another gap in the state's geologic and fossil record. More recently, during the Pleistocene, Rhode Island was scoured by glaciers. [2]
In Asia, the most recent late archaic human fossils were found in Thailand (125-100 ka), the Philippines (58-24 ka), Malaysia (c. 40 ka), and Sri Lanka (c.36 ka). [4] The artifacts from these sites include partial skeleton, crania, deep skull, and other related skeletons indicate that modern human migrated to Asia earlier than the western theory might have discussed.
[4] [8] Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, [9] rising to 72% in North America, 83% in South America and 88% in Australia, [10] with all mammals over 1,000 kilograms (2,200 lb) becoming extinct in Australia and the Americas, [1] and around 80% globally.

Although earlier dispersals had occurred, probably over water, the migration accelerated dramatically about 2.7 million years ago during the Piacenzian age. [1] It resulted in the joining of the Neotropic (roughly South American) and Nearctic (roughly North American) biogeographic realms definitively to form the Americas.
