Jack Hranicky is a retired U.S. Government contractor, but he has been involved with archaeology as a full-time passion for over 40 years. His main interest is the Paleo-Indian period; however, he has worked in all facets of American archaeology. He has published over 250 papers and over 35 books in archaeology with his most recent being a two-volume, 800-page, 10,000-artifact book on the material culture of Virginia. In Virginia, he is considered an expert on prehistoric stone tools and rockart. The prehistoric Spout Run Observatory site was investigated by him which dated 10,470 YBP. He has served as president of the Archeological Society of Virginia (ASV) and Eastern States Archeological Federation (ESAF), and been past chairman of the Alexandria Archaeology Commission in Virginia. He is a charter member of the Registry of Professional Archaeologists (RPA). And, since he joined the Archeological Society of Virginia (ASV) in 1966, he is its senior member. And finally, his major publication is Bipoints Before Clovis.

A Field Guide to Stone Artifacts of Texas Indians identifies and describes more than 200 dart and arrow projectile points and stone tools used by prehistoric Native Americans in Texas.

Paleoindians first arrived in Texas more than eleven thousand years ago, although relatively few sites of such early peoples have been discovered. Texas has a substantial post-Paleoindian record, however, and there are more than fifty thousand prehistoric archaeological sites identified across the state. This comprehensive volume explores in detail the varied experience of native peoples who lived on this land in prehistoric times. Chapters on each of the regions offer cutting-edge research, the culmination of years of work by dozens of the most knowledgeable experts. Based on the archaeological record, the discussion of the earliest inhabitants includes a reclassification of all known Paleoindian projectile point types and establishes a chronology for the various occupations. The archaeological data from across the state of Texas also allow authors to trace technological changes over time, the development of intensive fishing and shellfish collecting, funerary customs and the belief systems they represented, long-term changes in settlement mobility and character, landscape use, and the eventual development of agricultural societies. The studies bring the prehistory of Texas Indians all the way up through the Late Prehistoric period (ca. a.d. 700–1600). The extensively illustrated chapters are broadly cultural-historical in nature but stay strongly focused on important current research problems. Taken together, they present careful and exhaustive considerations of the full archaeological (and paleoenvironmental) record of Texas.
