Sometime before 1.8 mya Homo erectus had spread outside of Africa, reaching as far east as Java by 1.8 mya In these newly colonised areas, no Acheulean assemblages have been found.

In China, only "Mode 1" Oldowan assemblages were produced, while in Indonesia stone tools from this age are unknown.

By 1.8 mya early Homo was present in Europe, as shown by the discovery of fossil remains and Oldowan tools in Dmanisi, Georgia.

However, more recent classifications of Oldowan assemblages have been made that focus primarily on manufacture due to the problematic nature of assuming use from stone artefacts.

An example is Isaac et al.'s tri-modal categories of "Flaked Pieces" (cores/ choppers), "Detached Pieces" (flakes and fragments), "Pounded Pieces" (cobbles utilized as hammerstones, etc.) and "Unmodified Pieces" (manuports, stones transported to sites). Early Homo erectus appears to inherit Oldowan technology and refines it into the Acheulean industry beginning 1.7 million years ago.

and its flourishing with early species of Homo such as H. Oldowan stone tools are simply the oldest recognisable tools which have been preserved in the archaeological record.

There is a flourishing of Oldowan tools in eastern Africa, spreading to southern Africa, between 2.4 and 1.7 mya.

At 1.7 mya., the first Acheulean tools appear even as Oldowan assemblages continue to be produced.
