Between 4500 and 3500 years ago, partially intrusive Neolithic populations in the riverine basins of mainland Southeast Asia began to form mounded settlements and to develop economies based on rice cultivation, fishing, hunting, and the domestication

We investigated the utility of subfossil bat guano as a paleoenvironmental archive by comparing elemental ratios and δ13C, δ15N, and δD values of various simple extracts from bulk material. Solvent-extracted guano yielded consistent C:N and N:H ra

This study investigates the relationship between diet and cultural change in late Iron Age and Romano-British populations from Dorset, England (1st century BC to the early 5th century AD). Dorset was the only region in Britain to exhibit continuity i

Excavation of the Late Paleoindian Howard Gully site (34GR121) in southwestern Oklahoma revealed the remains of one to two bison in association with a shallow side-notched spear point. In some respects, this point style resembles San Patrice points f

The end of the Pleistocene in North America was marked by a wave of extinctions of large mammals, with the last known appearances of many species falling between ca. 11,000–10,000 14C yr BP. Temporally, this period overlaps with the Clovis Paleoind

Higham et al.'s (2005) recent article in Radiocarbon 47(3) concerning diet-induced anomalies on radiocarbon ages for various faunal samples from Shag River Mouth is a well-considered study, building upon methodologies and research questions examining

A consensus has not been reached on the validity of “old” (pre‐Polynesian settlement) 14C ages for Pacific rat bones from New Zealand. As an independent test of their validity, we have applied optical dating techniques to fossiliferous sediment

Radiocarbon ages of Rattus exulans bone recovered from the Pleasant River, Otago, archaeological site were originally rejected on the basis of 14C variability allegedly caused by laboratory processing Subsequent work revealed no burial contaminant th

Burial contamination can produce age anomalies in radiocarbon-d ated bone It is possible to test for the presence and effect of the in situ contamination — humic and fulvic acids, transferred in soil pore waters — for a specific site In this stud
