    An Anthropocene Without Archaeology—Should We Care?

    For more than a decade, a movement has been gathering steam among geoscientists to designate an Anthropocene Epoch and formally recognize that we have entered a new geological age in which Earth’s systems are dominated by humans. Chemists, climatologists, and other scientists have entered the discussion, and there is a growing consensus that we are living in the Anthropocene. Nobel Prize-winning atmospheric chemist Paul Crutzen (2002a, 2002b; Crutzen and Stoermer 2000) coined the term, but the idea that humans are a driver of our planet’s climate and ecosystems has much deeper roots. Italian geologist Antonio Stoppani wrote of the “anthropozoic era” in 1873 (Crutzen 2002a), and many others have proposed similar ideas, including journalist Andrew Revkin’s (1992) reference to the “Anthrocene” and Vitousek and colleagues (1997) article about human domination of earth’s ecosystems. It was not until Crutzen (2002a, 2002b) proposed that the Anthropocene began with increased atmospheric carbon levels caused by the Industrial Revolution in the late eighteenth century (including the invention of the steam engine in A.D. 1784), however, that the concept began to gain serious traction among scientists and inspire debate

    Geographic and Temporal Variability of Middle Holocene Red Abalone Middens on San Miguel Island, California

    For at least the last half-century, Middle Holocene "red abalone middens" have been of interest to a variety of scientists working on the Channel Islands of California. Paleoclimatologists, oceanographers, ecologists, and archaeologists have all offered hypotheses to explain their widespread occurrence; however, quantification of their midden constituents has generally been insufficient to explain both their temporal and spatial variability. Detailed zooarchaeological analysis is a key component in understanding why these middens appeared at about 7,500 cal B.P. and disappeared at about 3,300 cal B.P. Faunal data from three radiocarbon (carbon 14) dated red abalone middens on San Miguel Island are presented. The analysis demonstrates both the geographic and temporal variability inherent within these sites, and suggests that our models for explaining their presence must account for this complexity
