An archaeological excavate at Le Cotte de St Brelade in Brelade, Jersey, unearthed items which divulge the existence of Stone Age hunters at the bluff, The Register reported.
"In terms of the volume of residue, archaeological prosperity and deepness of time, there is nil else like it known in the British Isles," said Dr Matt Pope of the Institute of Archaeology at University College London, a research leader.
"Given that we consideration these deposits had been detached completely by earlier researchers, ruling that so much still leftovers is as thrilling as discovering a new site."
The site, which is off the coast of Normandy, France, has exposed more Neanderthal stone tools than the rest of the British Isles simultaneously. It holds the only known late caveman remains in Northwest Europe and an imminent into the early relatives of early human beings.
The archaeologists dated sediments at the cave site using a technique called optically enthused luminesce, which events the last time sand grains were uncovered to sunlight.
Dr Pope said the results showed that part of the succession of sediments dates between 100,000 and 47,000 years old, representing that Neanderthal teeth which were exposed at the site in 1910 were younger than earlier thought, and "doubtless belonged to one of the last Neanderthals to live in the region".
