The Clactonian is the name given by archaeologists to an industry of European flint tool manufacture that dates to the early part of the interglacial period known as the Hoxnian, the Mindel-Riss or the Holstein stages (c. 400,000 years ago). Clactonian tools were made by Homo heidelbergensis.
It is named after 400,000-year-old finds made by Hazzledine Warren in a palaeochannel at Clacton-on-Sea in the English county of Essex in 1911. The artifacts found there included flint chopping tools, flint flakes and the tip of a worked wooden shaft along with the remains of a giant elephant and hippopotamus. Further examples of the tools have been found at sites including Barnfield Pit and Rickson's Pit, near Swanscombe in Kent and Barnham in Suffolk; similar industries have been identified across Northern Europe. The Clactonian industry involved striking thick, irregular flakes from a core of flint, which was then employed as a chopper. The flakes would have been used as crude knives or scrapers. Unlike the Oldowan tools from which Clactonian ones derived, some were notched, implying that they were attached to a handle or shaft. Retouch is uncommon and the prominent bulb of percussion on the flakes indicates use of a hammerstone.
An "Egyptian version" of the Clactonian industry was proposed in 1972, based on excavations on the banks of the Nile River, at the 100 foot terrace.
The Clactonian industry may have co-existed with the Acheulean industry, which used identical basic techniques but which also had handaxe technology; tools made by bifacially working a flint core.
The justification for considering "Clactonian" as a tradition distinct from Acheulean has been called into question in a 1994 article.
The Clactonian industry may in fact be the same thing as the Acheulean and only assessed as being different due to its tools being Acheulean ones made by individuals who had no need for handaxes on the occasion that they made them.

The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age. It spans the time from around 3.3 million years ago when the first evidence for stone tool production and use by hominins appears in the current archaeological record, until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithics industries. In African archaeology, the time period roughly corresponds to the Early Stone Age, the earliest finds dating back to 3.
Not to be confused with industrial archaeology, the archaeology of (modern) industrial sites. In the archaeology of the Stone Age, an industry or technocomplex is a typological classification of stone tools. An industry consists of a number of lithic assemblages, typically including a range of different types of tools, that are grouped together on the basis of shared technological or morphological characteristics.
Acheulean (əˈʃuːliən; 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. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, East Asia and Europe, and are typically found with Homo erectus remains.
This experimental programme employs length-scale analysis of measured profiles to quantitatively discriminate the surface textures of stone flakes manufactured from East Anglian chalk flint used on four contact materials (shell, wood, dry hide and soaked a ...
