There are two reasons, according to Jim Adovasio, we don’t think of baskets or textiles when we think of the Stone Age. One is that stones and bones, being far more durable, are far more common at archeological sites than artifacts made of fiber... And yet it has been around a long time, as four small pieces of clay described by Adovasio this past year make clear. Found at a site called Pavlov in the Czech Republic, they are 27,000 years old--and impressed with patterns that could only have been created by woven fibers. These artifacts push back the date...

Prehistoric humans began gravitating to the Gault Site about 16,000 years ago, Texas State researchers say. The Gault Site is preserved forever because an archaeologist bought it and gave it to a conservation group... [Few academics have such wherewithal and fewer still would spend it this way, said Tom Dillehay, an anthropology professor at Vanderbilt University.] You can hardly walk 10 steps along Buttermilk Creek about 45 miles north of Austin without finding evidence that people lived here thousands of years ago. The ground is littered with flakes of chert, a plentiful stone from which projectile points, blades, cleavers and...

The bone was found below a layer that contained material from the Pleistocene period when the last ice age was thought to have occurred. The archaeologists identified the bison using an upper molar, which is thought to be representative of a Bison antiquus, a direct ancestor of the American bison that roamed North America until it became extinct. Because bison was a grassland-adapted animal, nearly 100 percent of their bones disintegrated after death unless they were preserved in some way. "This finding is especially significant because of the meticulous documentation that has been involved," said James M. Adovasio, Ph.D., principal...

Rediscovering AmericaThe New World may be 20,000 years older than experts thought BY CHARLES W. PETIT Late in the afternoon last May 17, a tired archaeological team neared the end of a 14-hour day winching muck to the deck of a Canadian Coast Guard vessel. It was in water 170 feet deep in Juan Perez Sound, half a mile offshore among British Columbia's Queen Charlotte Islands. For four days, team members had fruitlessly sieved undersea mud and gravel. Then, in the slanting light of sunset, a deckhand drew from the goop a triangular blade of dark basalt. Its sharp edge...
