Lewisville

an ancient hunters’ campsite near the town of Lewisville, Texas (USA). Excavations conducted between 1952 and 1957 revealed the remains of 21 hearths, in which were found the charred bones of extinct and living animals, including those of the mammoth, camel, bison, giant turtle, horse, coyote, Virginia deer, and prairie dog. Articles made of quartzite and flint—a chopper, hammer, end scraper, and flakes—were found near the hearths. A Clovis-type fluted speartip was found in the largest hearth. The radiocarbon age (more than 38,000 years before the present) of the finds corresponds to the geological conditions of the site’s stratification. The speartip, which dates between 9,000 and 13,000 years before the present, could in the opinion of some archaeologists have found its way into the layer at a later time.
