Acheulean (/ ə ˈ ʃ uː l i ə n /; also Acheulian and Mode II), from the French acheuléen after the type site of Saint-Acheul, is an archaeological industry of stone tool manufacture characterized by the distinctive oval and pear-shaped "hand axes" associated with Homo erectus and derived species such as Homo heidelbergensis.
A hand axe (or handaxe or Acheulean hand axe) is a prehistoric stone tool with two faces that is the longest-used tool in human history. [1] It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by knapping , or hitting against another stone.
Cleavers, found in many Acheulean assemblages such as Africa, were similar in size and manner of hand axes. The differences between a hand axe and a cleaver is that a hand axe has a more pointed tip, while a cleaver will have a more transverse "bit" that consists of an untrimmed portion of the edge oriented perpendicular to the long axis of the tool.
The abundant hand axes are characteristic of the Acheulean period, made by hominins between about 600,000 and 900,000 years ago [7] along what was then the shore of a now dried-up lake. Fossils of various animals have also been found, including those of extinct species of hippo, elephant, zebra, giraffe, and baboon, likely to have been ...
In the late Acheulian (500-300 thousand years before present, hereinafter - Thyr) Armenia, tools (bifaces), hand axes, were found, made of double-sided pieces of obsidian and dacite, leaf-shaped, with sharp, symmetrical edges, the thick part of the base of the tools adapted to the human palm.
An Acheulean handaxe approximately 12 cm in height, similar to those found at Kariandusi Acheulean hand-axes made of obsidian and trachyte from the Kariandusi Museum in Kenya. When this site was discovered and initially researched, the finds were sent to museums all around the world (as was common at the time).
When it’s whipped with a hand or stand mixer, aquafaba, aka the liquid leftover from a can of chickpeas, can mimic the texture and consistency of egg whites for meringues or vegan cocktails like ...
In the early twentieth century, these gravel pits yielded many Paleolithic tools of the Acheulian and Levallois industries, associated with the Neanderthals, including the largest hand axe ever found. The site is in the Lynch Hill Terrace of the River Thames, dating to the Wolstonian Stage between 350-200,000 years ago. [4] [5]
