300,000 Year-old Stone Artefacts Discovered

Researchers at University College London have discovered some of the largest early prehistoric stone tools in Britain. The discoveries were made at Frindsbury in Kent where artefacts were recovered from deep Ice Age deposits above the Medway Valley. A total of eight hundred stone artefacts believed to be over 300,000 years old were recovered.

The unearthed artefacts included two very large flint knives described as “giant handaxes.” It is thought that this type of tool was usually held in the hand and may have been used for butchering animals and cutting meat.

The largest handaxe measured 29.5cm in length and is currently the third largest known to be found in Britain. ‘Giant handaxes’ like this are usually found in the Thames and Medway regions and date from over 300,000 years ago.

Letty Ingrey, a senior archaeologist from the University College London Institute of Archaeology, explained that they likely date back to an interglacial period approximately 300,000 to 330,000 years ago.

“While right now, we aren’t sure why such large tools were being made, or which species of early human were making them, this site offers a chance to answer these exciting questions.”

stated Ms Ingrey.

The site is thought to date to a period in the early prehistory of Britain when Neanderthal people and their cultures were beginning to emerge and may even have shared the landscape with other early human species. During this period the Medway Valley would have been a wild landscape of wooded hills and river valleys, where red deer, horses, now-extinct straight-tusked elephants, and lions roamed freely.

Throughout Africa and Europe, handaxes have been discovered at various archaeological sites dating back from 1.7 million to 300,000 years ago. By 200,000 years ago, many innovations had been made in stone tool technology. For example, large handaxes became less common and were replaced with a range of smaller tools in more diverse toolkits. Tools made of flakes were favoured over large cores.

Today, modern humans or Homo sapiens, inhabit the whole earth. Looking back over the last half a million years, the picture was much more diverse, with three distinct lineages appearing: Homo erectus in Asia; and Homo heidelbergensis giving rise to Homo neanderthalensis in Europe and Homo sapiens in Africa.

The Neanderthals thrived in Europe for around 300,000 years before modern humans arrived. Neanderthals occupied Europe for at least 100,000 years during a period when glacial cycles dominated the climate. Excavations in Ibex, Vanguard, and Gorham’s Caves in Gibraltar have revealed evidence of Neanderthal occupation dating to possibly as late as 28,000 years ago.

The ancestors of modern humans interbred with Neanderthals and another extinct line of humans known as the Denisovans. Modern humans, Neanderthals and Denisovans shared a common ancestor who lived roughly 600,000 years ago.
