| In Europe and North America, the Holocene is subdivided into Preboreal, Boreal, Atlantic, Subboreal and Subatlantic stages of the Blytt-Sernander time scale. There are many regional subdivisions for the Upper or Late Pleistocene, usually these represent locally recognized cold (glacial) and warm (interglacial) periods. The last glacial period ends with the cold Younger Dryas substage. | |||
The Soanian is an archaeological culture of the Lower Paleolithic (ca. 500,000 to 1250,000 BP) in Pakistan, contemporary to the Acheulean. It is named after the Soan Valley in the Sivalik Hills, Pakistan. The bearers of this culture were Homo erectus.
On Adiyala and Khasala about 16 km (10 miles) from Rawalpindi terrace on the bend of the river hundreds of edged pebble tools were discovered. At Chauntra hand axes and cleavers were found. No human skeletons of this age have yet been found. In the Soan River Gorge many fossil bearing rocks are exposed on the surface. 14 million year old fossils of gazelle, rhinoceros, crocodile, giraffe and rodents have been found there. Some of these fossils are on display at the Natural History Museum of Islamabad.
