The Acheulian tools at Kokiselei were found just above a sediment layer associated with a polarity interval called the “Olduvai Subchron.” It is named after Tanzania’s Olduvai Gorge, where pioneering work in the 1930s by Leakey’s parents, Louis and Mary, uncovered a goldmine of early human fossils. 4. The earliest Acheulean handaxe yet found is from the Kokiselei 4 site in the Rift valley … D. Acheulean tools show representations of the human form on nonfunctional surfaces. Named for St. Acheul on the Somme River in France, where the first tools from this tradition were found in the mid-19th century, Acheulean tools spread from Africa over … Although they are in many (but not all) Homo erectus sites from Southern Africa to the British Isles, so far they have been uncovered at only one H. erectus site in East and Southeast Asia There are no Acheulian tools at H. erectus sites E. Acheulean tools constitute a move away from wood toward more plastic media like clay. Oldowan tools have been discovered near Lake Turkana as well, in sediments estimated to be 2.34 million years old; Acheulean tools appear by 1.65 mya. The basic toolkit, including a variety of novel forms of stone core, continued to be made. The FIRST recorded Acheulian hand axes in the world were found in East Africa making this from the earliest time in human history of this period. It and the Acheulean toolkit were made for an immense period of time – ending in different places by around 400,000 to 250,000 years ago. The Acheulean handaxe is named after the Saint Acheul archaeological site in the lower Sommes valley of France where the tools were first discovered n the 1840's. These tools and other kinds of ‘large cutting tools’ characterize the Acheulean toolkit. The earliest fossils of Homo erectus found outside of Africa were first discovered in the late 1800s in Java, Indonesia. C. Oldowan tools are based on the production of blades, associated with an increasing range of ways hominins exploited their biological and cultural environments. replica of KNM-ER 1470 Replica of KNM-ER 1470, a reconstructed Homo habilis skull found in 1972 at Koobi Fora, Kenya, by a team under Richard Leakey. The tools that were used in the lower Paleolithic period 2.5 MYA (million years ago) up until 1.76 MYA, were most notable and used by Late Australopithecus and early Homo habilis and found across most of Europe, the Middle East, Africa and South Asia. The The earliest fossils of Homo erectus have been discovered in Asia and other fossil remains have been found in East African sites in Kenya, Tanzania, and Ethiopia. “What we have in the Bose basin is the most Acheulean-like assemblage of stone tools ever found in East Asia, requiring the same behavioral and technical competence.” He adds that not only the shape of the tools but also how they were made and strewn across the land is similar to Acheulean sites. Homo erectus first left Africa about 1.8 million years ago. The most comprehensive sequences are found in East Africa, where, in large-scale syntheses, the Lower Pleistocene Acheulean (LPA) has often been considered a uniform cultural entity.
