DOWNLOAD EBOOKIt is difficult for today's students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision. Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated. Rather, common practice is to categorize them under the heading `stratigraphic excavation'. This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time - a point little appreciated by modern archaeologists. Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: seriation and the use of index fossils. The latter (like stratigraphic excavation) measures time discontinuously, while the former - in various guises - measures time continuously. Perhaps no other method used in archaeology is as misunderstood as seriation, and the authors provide detailed descriptions and examples of each of its three different techniques. Each method and technique of relative dating is placed in historical perspective, with particular focus on developments in North America, an approach that allows a more complete understanding of the methods described, both in terms of analytical technique and disciplinary history. This text will appeal to all archaeologists, from graduate students to seasoned professionals, who want to learn more about the backbone of archaeological dating.

DOWNLOAD EBOOKWith the tremendous growth of population in this and neighboring states, there are more collectors than ever before and with the rapidly escalating prices for mineral and fossil specimens in the retail market, there is a great demand for displayable material. It has become necessary for professional geologists, hobby collectors, and commercial collectors to recognize each others existence and to try to work together within a framework of regulation, courtesy, and common sense so that material of scientific value is not lost and undue restrictions are not placed upon collecting. There is a continuing need for collectors and professionals to work together with resource managers and legislators to develop workable laws and rules affecting the collecting of minerals and fossils. This publication contains details information about collecting areas, divided by county to make for ease of use. Each collecting area contains information about the minerals, rocks, or fossils present, map recommendations, and other helpful tips on getting to the sites.

DOWNLOAD EBOOKThis book gathers the findings of a number of studies on North American cave paleontology. Although not intended to be all-inclusive, Ice Age Cave Faunas of North America contains contributions that range from overviews of the significance of cave fossils to reports about new localities and studies of specific vertebrate groups. These essays describe how cave remains record the evolutionary patterns of organisms and their biogeography, how they can help reconstruct past ecosystems and climatic fluctuations, how they provide an important record of the evolution of modern ecosystems, and even how some of these caves contain traces of human activity. The book's eclectic nature should appeal to students, professional and amateur paleontologists, biologists, geologists, speleologists, and cavers. The contributors are Ticul Alvarez, Joaquin Arroyo-Cabrales, Christopher J. Bell, Larry L. Coats, Jennifer Glennon, Wulf Gose, Frederick Grady, Russell Wm. Graham, Timothy H. Heaton, Carmen J. Jans-Langel, Ernest L. Lundelius, Jr., H. Gregory McDonald, Jim I. Mead, Oscar J. Polaco, Blaine W. Schubert, Holmes A. Semken, Jr., and Alisa J. Winkler.
