Continue the debate about the first Americans in Texas

Stone tools workers lived in Texas more than 16,000 years ago, before Clovis hunters came here.

According to the researchers, there was evidence of people who lived in what is now the center of Texas a few thousand years ago hunters from the ancient Clovis culture of North America.

According to a research group led by archaeologist Thomas Williams from Texas State University, San Marcos, excavations at the Gault site , about 64km north of Austin, have uncovered a series of artifacts. Stone work dates from about 16,700 to 21,700 years ago. According to the scientists' conclusions on July 11 Science Advances, an analysis of 184 samples of the findings identified 11 very different spears that were found in ancient locations in the United States.

Artifacts discovered by archaeologists.

Researchers have long debated whether there were people coming to North America before the Clovis culture was born 13,000 years ago. Evidence from the location Gault has the same opinion with other recent reports about how people venture into North America much longer than before. This will remove the Clovis from the list of the first New World settlers.

Williams' team estimated the date of the Clovis money discovery in Gault by a method of calculating the time since the sedimentary layer contained artifacts exposed to the sun.

Previous studies at the location of Gault have discovered Clovis spears and other devices from about 13,000 years ago, as well as other tools and artifacts made by recent age groups around several thousand years ago. Investigators said some of the recently discovered stone tools in Gault, such as small rectangular cutting tools, show similarities to Clovis tools. The team claims, in general, earlier artifacts belong to a different tool-making culture of the Clovis culture.
