the most common stone tool type from the acheulean industry is
Acheulean Acheulean (/əˈʃuːliən/; also Acheulian and Mode II), from the French acheuléen, is an archaeological industry of stone tool manufacture characterized by distinctive oval and pear-shaped "hand-axes" associated with early humans. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, and Europe, and are typically found with Homo erectus remains. It is thought that Acheulean technologies first developed in Africa out of the more primitive Oldowan technology as long as 1.76 million years ago, by Homo habilis. Acheulean tools were the dominant technology for the vast majority of human history.[3][4][5]
Archaeoastronomy When debates polarise between techniques, the methods are often referred to by a colour code, based on the colours of the bindings of the two volumes from the first Oxford Conference, where the approaches were first distinguished.[53] Green (Old World) archaeoastronomers rely heavily on statistics and are sometimes accused of missing the cultural context of what is a social practice. Brown (New World) archaeoastronomers in contrast have abundant ethnographic and historical evidence and have been described as 'cavalier' on matters of measurement and statistical analysis.[54] Finding a way to integrate various approaches has been a subject of much discussion since the early 1990s.[55][56]
En plein air Artists have long painted outdoors, but in the mid-19th century, working in natural light became particularly important to the Barbizon school, Hudson River School, and Impressionists.
