Texas researchers have discovered what they think are spikes used by human hunters about 15,500 years ago, making them the oldest weapons ever found in North America.
The newly discovered hubs predict the earliest known weapons made by the Clovis people, whom archaeologists long believed were the first people to settle in America 13,000 years ago.
The team of researchers from Texas A & M, Baylor University and the University of Texas was made at an archaeological site about 40 miles northwest of Austin, named Debra L. Friedkin, after the family that owns the country. Excavations on the site have been going on for more than a decade.

Researchers revealed many spearheads of chert, a type of rock, as well as other tools, buried in sediment layers as they revealed dating was at least 15 500 years old. Unlike the characteristic spear-shaped stone weapons called Clovis Points, found in Texas as well as other parts of the United States and Northern Mexico dating between 12 700 and 13 000 years ago, these older “western stämed” spear points is smaller, without the clear Clovis tracks.

Water and his team believe that the earliest Americans used these spears pointing to chasing mothers and the other big animals that strove what is now Central Texas more than 15,000 years ago. Their findings, published in the journal Science Advances may force researchers to rethink the accepted wisdom of human settlement in North America – once again.

Archaeologists long believed that the first people settled in America did it about 13,000 years ago by going from Alaska through an ice-free corridor in western Canada before going south. But the discovery of Monte Verde settlement in southern Chile, dating back at least 14,500 years, pointed to that theory, because the ice-free road through Canada was not there at that time.
The new discovery of Texas can also help to rewrite the long-accepted timeline and offer potential support for the theory that the earliest Americans may have landed, but at sea, at different points along the Pacific coast.
“The findings extend our understanding of the earliest people to explore and settle in North America,” Waters said. “Americas at the end of the last Ice Age was a complex process and this complexity is seen in their genetic records. Now we begin to see this complexity reflected in the archaeological record.”
