A man walking along a beach in Scotland found a Paleolithic axe head that could be 450,000 years old!

62-year-old Alan Price stumbled upon something totally unexpected - even by archaeological standards, while casually looking for semi-precious on the beach. Price came across a 14-centimeter long flint axe that could be anywhere from 100,000 to 450,000 years old! Less than 10 of these types of specimens have been discovered in Scotland, which means the find is extremely exciting. Archaeologist Caroline Wickham-Jones says that it could push back Scotland’s known prehistory by at least 86,000 years! The only trouble is that they must now ascertain where the axe head is originally from, because it did not necessary come from Orkney, the area in which it was found.
