This flint handaxe is from Norfolk County in East Anglia, England. It likely dates to the Mousterian (Middle Palaeolithic) period, ca. 41,000-59,000 BP.
The Acheulean period ended by about 300,000 BP in Europe, replaced by technologies focussed on prepared cores and made by Neanderthals and modern humans like us, but bifacial handaxes remained a persistent element of later European toolkits. Notable among these are the well-made bifacial handaxes of the ‘Mousterian of Acheulean Tradition’, dating to ca. 50,000 BP and associated with the Neanderthal occupation of Europe. These handaxes are relatively small, well-made, and are triangular, sub-triangular, or cordate (almond- or heart-shaped). Bout coupé handaxes—cordiform in shape but with a straight or slightly excurvate butt—are considered the hallmark of Britain’s recolonisation by Neanderthals, ca. 41,000-59,000 BP.
