Over the past thirty years, late Quaternary environments in the arid interior of western North America have been revealed by a unique source of fossils: well-preserved fragments of plants and animals accumulated locally by packrats and quite often encased, amberlike, in large masses of crystallized urine. These packrat middens are ubiquitous in caves and rock crevices throughout the arid West, where they can lie preserved for tens of thousands of years. More than a thousand of these deposits have been dated and analyzed, and middens have supplanted pollen records as a touchstone for studying vegetation dynamics and climatic change in radiocarbon time (the last 40,000 years). Now, similar deposits made by other mammals like hyraxes are being reported from other parts of the world. This book brings together the findings and views of many of the researchers investigating fossil middens in the United States, Mexico, Africa, the Middle East, and Australia. The contributions serve to open a forum for methodological concerns, update the fossil record of various geographic regions, introduce new applications, and display the vast potential for fossil midden analysis in arid regions worldwide. The findings presented here will serve to foster regional research and to promote general studies devoted to global climate change. Included in the text are more than two hundred charts, photographs, and maps.
Original research, survey/review work, initial reports and other information on fossils from Arizona. Topics include paleobotany, geology, paleontology, and paleoecology. Originally presented at the 1995 Symposium held at the Mesa Southwest Museum.
Presenting the most current research and thinking on prehistoric archaeology in the Southeast, this volume reexamines some of Florida’s most important Paleoindian sites and discusses emerging technologies and methods that are necessary knowledge for archaeologists working in the region today. Using new analytical methods, contributors explore fresh perspectives on sites including Old Vero, Guest Mammoth, Page-Ladson, and Ray Hole Spring. They discuss the role of hydrology—rivers, springs, and coastal plain drainages—in the history of Florida’s earliest inhabitants. They address both the research challenges and the unique preservation capacity of the state’s many underwater sites, suggesting solutions for analyzing corroded lithic artifacts and submerged midden deposits. Looking towards future research, archaeologists discuss strategies for finding additional pre-Clovis and Clovis-era sites offshore on the southeastern continental shelf. The search is important, these essays show, because Florida’s prehistoric sites hold critical data for the debate over the nature and timing of the first human colonization of the Western Hemisphere.
