LA-ICP-MS analysis of the chemical composition of the exterior slips and red and black pigments used for painted decoration of the three Postclassic Maya slipped ceramic wares suggests that the Itzá and Kowoj used different pigments for exterior slips and decorative motifs. Additionally, different slips and paints were used depending on vessel form and decorative program (red, black, or red-and-black painting or incising). When examined with previous ceramic paste chemical analyses, the data aid in better understanding the changing socio-political alliances and dominance relations in central Petén at the eve of Spanish contact. 相似文献

The analysis of dental crown heights in a sample of known-age American Red deer (known in America as “elk”) has permitted the derivation of formulae for the prediction of age from crown height. The ages predicted from crown heights closely approximate true ages, when both predicted and true ages are grouped into broad, but still useful age classes. At least for the Red deer or “elk” dP4, M2 and M3, age prediction formulae very similar to the empirically derived ones may be constructed by making certain hypothetical assumptions about the nature and rate of crown attrition. This suggests that these assumptions may be used to construct age prediction formulae in situations where an empirical relationship between age and crown height has not been or cannot be established. With certain provisos noted in the text, the age prediction formulae that result will probably provide reasonably reliable age profiles for the numerous ungulate species whose teeth are similar in structure to those of Red deer or “elk” and at least as hypsodont. 相似文献

To evaluate coastal settlement and land use strategies among maritime hunter-gatherers, we analyzed oxygen isotope (δ18O) data from 131 marine carbonate samples from 21 California mussel (Mytilus californianus) shells obtained from a large ~8,200-year-old shell midden (CA-SRI-666) on California’s Santa Rosa Island. Seasonal distributions of the isotopic data were assigned using a paleo-sea surface temperature model created by comparing modern sea surface temperatures (SST) to a fully profiled ~8,200-year-old shell. For 20 additional shells, we used two sampling strategies to compare season-of-harvest inferences and explore whether the Early Holocene site occupants were sedentary. Estimated season-of-harvest differed by 35 % between the two sampling methods, corroborating recent isotope analysis of an 8,800-year-old shell midden on San Miguel Island. Shellfish appear to have been collected year-round at CA-SRI-666 from intertidal or subtidal water temperatures similar to modern SST in the vicinity of eastern Santa Rosa Island. The isotope results are consistent with other evidence from CA-SRI-666 that suggest that the site served as a residential base for relatively sedentary maritime people. 相似文献

The earliest documented excavation of an effigy mound group by a professional archaeologist occurred in 1883 when Frederic Ward Putnam and local acquaintances excavated portions of four mounds at the Myrick Park site (47Lc10) in La Crosse, Wisconsin. Putnam worked on one effigy (similar to the short-tailed turtle form) and three conical mounds. Theodore H. Lewis visited the site in 1885 and mapped one additional conical mound. We examined documentation and collections housed at the Peabody Museum of Archaeology and Ethnology at Harvard University. Artifacts include a portion of a Madison Cord Impressed jar (a common Effigy Mound offering) and a trailed rim sherd similar to terminal Late Woodland types. Human remains represent a minimum of 23 individuals: 18 adults and 5 subadults. Dental and skeletal evidence indicates a relatively healthy population with low levels of nutritional deficiency, early life stress, and trauma, similar to other regional Late Woodland populations. 相似文献
