CUMBRIA, ENGLAND—An excavation conducted in northern England ahead of a road improvement project along an ancient pathway has uncovered flint tools dated to the Upper Paleolithic period, according to a Newsweek report. The tools could be between 10,000 and 14,000 years old, when the climate would have been colder. Hunter-gatherers likely followed herds of reindeer, wild horses, and wild cattle over a wide range, said archaeologist Stephen Rowland. The tools were found in a pit that had been sealed by soil that washed down a nearby slope. The researchers will look for traces of an encampment that may have also been preserved through the same process.
