Potassium argon dating hominids

In some regions Acheulean tool-using groups were contemporary with other, less sophisticated industries such as the Clactonian.

Then, later, Acheulean tools occur at the same time as the more sophisticated Mousterian.

It reached its peak with early species of Homo such as H. Acheulean is the industry of stone tool manufacture by early humans of the Lower Palaeolithic era in Africa and much of West Asia and Europe.

They lived by gathering plants and hunting wild animals.

The Oldowan is the archaeological term used to refer to the stone tool industry that was used by hominids during the earliest Palaeolithic period.

They are first developed out of the more primitive Oldowan technology some 1.8 million years ago, by Homo habilis.

It was the dominant technology for most of human history.

They are found in Europe somewhat later, from about 1 mya (0.7mya for Britain).

The Palaeolithic is by far the longest period of humanity's time, about 99% of human history.They were made by all previous members of the genus, starting with relatively crude tools made by Homo habilis and Homo erectus.In Europe, the large-brained Neanderthal Man (Homo neanderthalensis) made tools of high quality, and was in turn outshone by the many tools made by our own species.The earliest user of Acheulean tools was Homo ergaster who first appeared about 1.8 million years ago.Some researchers prefer to call these users early Homo erectus.He had found them in prehistoric lake deposits along with the bones of extinct animals and concluded that they were made by people "who had not the use of metals" and that they belonged to a "very ancient period indeed, even beyond the present world".
