Useful for academic and recreational archaeologists alike, this book identifies and describes over 200 projectile points and stone tools used by prehistoric Native American Indians in Texas. This third edition boasts twice as many illustrations—all drawn from actual specimens—and still includes charts, geographic distribution maps and reliable age-dating information. The authors also demonstrate how factors such as environment, locale and type of artifact combine to produce a portrait of theses ancient cultures.
Since World War II, there has been tremendous success in the development of new methods for dating artifacts; the so-called `radiocarbon revolution' was only the first such discovery. The increasing accuracy of the various new techniques has brought about major changes in archaeological research strategies. This important new text compiles the work of some of today's most innovative archaeologists who summarize progress in their respective techniques over the last 30 years - with an emphasis on developments of the last five - and the status of current research.
The Higgins site, 41BX184, is a mainly prehistoric site (spanning the last 6,000 to 7,000 years) containing abundant remains and is situated on a middle to late Holocene terrace along Panther Springs Creek in northern Bexar County. It was archaeologically investigated in 1992 and 1993 as part of work done along the Wurzbach Parkway in accordance with Section 106 of the National Historic Preservation Act.
