MINIMALLY DESTRUCTIVE RADIOCARBON DATING OF CAPRINE DUNG
نویسندگان
چکیده
ABSTRACT Archaeological dung pellets are time capsules of ancient herbivore diets and gut flora, informing on past agropastoral activity, ecology, animal health. Improving multi-proxy approaches is key to maximizing this finite archaeological resource. Through experiments with standard pretreatments used in radiocarbon ( 14 C) dating, we address a fundamental problem maximal analysis: How chronometrically date individual caprine while conserving as much possible for additional analyses? We applied acid-alkali-acid (AAA) or acid-only 37 samples recent sheep/goat from sites the Negev desert, Israel, measuring weight-loss due pretreatment. Shavings outer surfaces remaining inner four pairs were dated compared. found that (i) sample-specific factors affect pretreatment survivability, including preservation quality initial sample size; (ii) given sufficient start weight, AAA can be pretreat coprolites; (iii) 100 mg appeared desirable minimum weight before pretreatment; (iv) shavings coprolites’ surface produced C dates equivalent obtained coprolites. Whereas coprolite analysis protocols discard removed avoid contamination, our findings indicate their efficacy dating. This offers an important addition workflows analysis.

Radiocarbon Dating of Ground Water
Radiocarbon dating of ground water is used in combination with the primary measurements of classical hydrological and chemical analyses. Radiocarbon dating will produce the best results when it involves multiple measurements or sequential sampling. The most useful data come from these comparisons and not from absolute ages. In the case of multiple measurements, the apparent ages of the ground w...

Radiocarbon (I4C) dating, now in its fifth decade of general use, continues to be the most widely employed method of inferring chronometric age for late Pleistocene and Holocene age materials recovered from archeological contexts. Over the last decade, several technical advances in I4C studies have provided contexts for a number of significant applications in archeology that were previously eit...

grassland and not going anywhere are no longer cowpaths. The photograph shows the currently used paths in the grassland bowed toward the lower left by encroaching shrubs while faint scars above reveal where the paths once passed. In the grassland these old paths are obliterated by grass; in the shrub zone they remain bare and become broader. The great broad white zones of bare ground both insid...
