Not far from the Arctic Circle, Stone Age tool makers left hard evidence to understand. Artifacts found in this area imply that tool makers worked in frigid conditions. The tools that where discovered where a resemblance of cutting tools, and carpentry tools. The time of when the tools where being formed show that the stone-age was very confined. The settlers that made these tools, kept them to themselves with the older stone-age culture being preserved. Stone-Age tools attributed to modern human societies, which as early as 45,000 years ago, include small rectangular blades and spear points. Ludovic Slimak, the finder of these artifacts, explained that the tools used not only by Stone Age people but by some recent hunter-gatherers to kill and butcher animals. Slimak and his team studied more than 300 stone artifacts and 4,000 animal bones that have been excavated since 1996. The artifacts include cutting tools and large rocks from which they have been removed with pounding stones. Nearly two dozen mammoth, reindeer, and brown bear bones, display butchery marks. This was a huge finding in their study of the exact time of the Stone Age. The way they find how long these artifacts have been buried is by measurements of carbon decay in bones.

These studies are great, because we have yet to learn the truth behind the Stone Age. There have been plenty of different ideas of when it occurred. But, finings and studies of this caliber will succeed in our goal to find the accurate timing.
