Single amino acid radiocarbon dating of Upper Paleolithic modern humans [Anthropology] Archaeological bones are usually dated by radiocarbon measurement of extracted collagen. However, low collagen content, contamination from the burial environment, or museum conservation work, such as addition of glues, preservatives, and fumigants to “protect” archaeological materials, have previously

Geomorphological evidence for fluvial change during the

Chronostratigraphy is the branch of stratigraphy that studies the age of rock strata in relation to time.. The ultimate aim of chronostratigraphy is to arrange the sequence of deposition and the time of deposition of all rocks within a geological region, and eventually, the entire geologic record of the Earth.

07.02.2020 · The radiocarbon date at 500 cm is older than > 35 kyr; therefore, the calibrated age can be considered less robust than the younger radiocarbon dates. A second, independent, downcore age model using δ 18 O stratigraphy was constructed, as the deeper depths (> 500 cm) of the core are beyond the limits of radiocarbon dating.

The lower distribution limit of solifluction lobes is at 2300 m a.s.l. (Stingl 1969). Radiocarbon dating of fossil soils buried by solifluc¬ tion determined that the big lobes originated mainly during two activity periods, 3350-2800 l4C yr B.P. and around 1250 NC yr B.P.. following an Early-to Mid-Holocenc period with stable slopes and soil

Identification of a new hominin bone from Denisova Cave

Within the upper 44 m w.e., a total of six samples were analysed, typically comprising between 40 and 60 cm of core. For the KCI ice core more core material (one-third) was available, resulting in depth intervals of 40 cm length used for radiocarbon dating. Within the upper 40 m w.e. of the KCI core six samples have been analysed so far.

The radiocarbon dating of vermetid shells constrains the timing of uplift for the Krios paleo-beach and notch. The ages are reported in radiocarbon years (yr) and fraction modern (fm) (Table 1). The samples, collected at and below the notch (Fig. 2), yielded radiocarbon ages of 2672±24 yr BP (2844–2300 cal yr BP) and 2397±25 yr BP (2116–1941 cal yr BP) for the uplift, respectively.
