An End Scraper was a heavy duty tool that was used for scraping fur from animal hides and removing the fatty tissue from its underside. I know these are the artifacts I seen in that book and will prove these are the first inhabitants of the North American continent. This can be used in conjunction with the other principles listed here - Superposition see below and Lateral Continuity see above. These tools were usually made of basalt, rhyolite, granite stones whose coarse structure made them ideal for grinding other materials, including plants and other stones. He is both a co-owner and co-founder of Ancient Origins. Blade Core This artifact was used to provide stone blades. This rules out geofacts as we have looked in fields full of flints and found nothing. Used by to manufacture stone tools, such as spear and dart points, knives, and tools.


Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place. Even when the only science we had to go on was religious literature and the western world believed the world was created in BC 1 , scholars tried to figure out when each biblical event took place, to define a chronology from savagery to civilization, from creation to the first animal, then to the emergence of the first people. The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences. As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past. All dating methods today can be grouped into one of two categories: absolute dating , and relative dating. The former gives a numeric age for example, this artefact is years old ; the latter provides a date based on relationships to other elements for example, this geological layer formed before this other one. Both methods are vital to piecing together events of the past from the recent back to a time before humans and even before complex life and sometimes, researchers will combine both methods to come up with a date. Some of the methods covered here are tried and tested, representing early methods of examining past geological, geographical, anthropological and archaeological processes. Most are multidisciplinary, but some are limited, due to their nature, to a single discipline. No system is completely failsafe and no method completely correct, but with the right application, they can and have aided researchers piece together the past and solve some of their discipline's most complex problems.


Until recently, if you asked most experts when the first human beings arrived and settled in North America, you'd get an answer along the interracial dating events of 13, years ago.

But over the last few years, evidence has been mounting that humans arrived at the continent earlier. And now a massive discovery of hundreds of thousands of stone tools suggest fools might have to push the date of human settlement back by at least 2, years.

Since the initial discovery, stone tools dating to the Clovis period have been uncovered in various other tols across North dwting South America, but the new find adds to the growing body of evidence that people arrived on this continent long before then.

Williams and his team have uncovered aroundstones modified by the hands of humans at the Gault dig, which is around 64 kilometres 40 miles north of Austin, analysing close to of them. They would have can ted talks dating hack can used as blades, engraving tools,, and more.

Some of these objects cloud date as far back as 20, years, according to the researchers, and look to be at least 16, years old — that's based on an optically stimulated luminescence process, where exposing artefacts to light and measuring the click here energy can determine when those artefacts last saw sunlight.

Add the dating to the techniques used to make these tools, which seem to be different from the various Clovis finds, and it looks as though dating stone tools might have to find "a more elaborate framework" for how civilisation begin in this part of the world, the team writes.

This isn't the first occasion that the Clovis timeline has been called into question, and the some researchers are now moving stoone the idea that people were living in the Americas much earlier.

All kinds of clues — like how humans might have travelled from Asia — are being reassessed. This particular part of the world would have appealed as a place to settle — it would have offered plenty of wild springs for feeding people and animals, as well as an abundance of flinty outcrops for fashioning tools like these. Indeed the site has a long dating stone tools, and the researchers have previously found tools matching the date and design of previous Clovis finds at the dig too.

All the signs from the Gault dig seem to suggest that the tool-making technology of the Clovis period spread across a population that was already dating stone tools and indigenous, rather than one that had datinng arrived, the researchers conclude. So it looks as if we have a new page of history to write, and an earlier starting date for humans in North America — at least until the next discovery.
