In our numbering system, this corresponds to rings −31 to −26, where the waney edge is assigned to be 0, the penultimate ring is assigned to be −1, and so forth. The items were found at the locations shown on the site map in Extended Data Fig. The association of these pieces with the Norse is based on detailed research previously conducted by Parks Canada. The determining factors were their location within the Norse deposit and the fact that they had all been modified by metal tools, evident from their characteristically clean, low angle-in cuts30. Such implements were not manufactured by the Indigenous inhabitants of the area at the time30 . 993 anomaly has been detected, it simply becomes a matter of counting the number of rings to the waney edge.

Subsequently, a sample from the fossil forest was used in an interlaboratory test, with results provided by over 70 laboratories. These tests produced a median age of 11,788 ± 8 BP (2σ confidence) which when calibrated gives a date range of 13,730 to 13,550 cal BP. The Two Creeks radiocarbon dates are now regarded as a key result in developing the modern understanding of North American glaciation at the end of the Pleistocene. 1 to 6 show typical artefacts from the excavations, as can be found in the Extended Data, Fig. 7 displays a map of the study area and the neighbouring excavation ASR 9 Posthuset from 1990 to 1991, and Figs. 8–13 are related to radiocarbon analyses, calibration curves and age models.

Upwelling mixes this “old” water with the surface water, giving the surface water an apparent age of about several hundred years . This effect is not uniform – the average effect is about 400 years, but there are local deviations of several hundred years for areas that are geographically close to each other. Professor Willard Libby, a chemist at the University of Chicago, first proposed the idea of radiocarbon dating in 1946.

The large amount of pottery from its stratified contexts allows the comparative study of several Aegean pottery styles, in a region where pottery sequences of the Early Iron Age have until now been known almost exclusively by means of burial contexts. The finds from Sindos include non-local ceramic wares from many different Aegean micro-regions, such as Euboea, Attica and Corinth, and of course Macedonia. Regional correlations between the chronologies of the central and southern Aegean were already developed by Coldstream, as demonstrated in his most influential book on the Greek Geometric Pottery . At that time any synchronization with the northern ‘periphery’ was still unthinkable. The Greek relative chronological system still suffers from all biases and ambiguities that resulted from its construction by means of burial contexts given that evidence from stratigraphies was practically missing.

A much shorter paper eliminating sections 2-4 to a short summary and arguing the reasons for a re-dating and that proposal seem reasonable to me.

A more detailed description of the contexts of the bone samples can be taken from the section profiles and plans, which are available and analytically commented in the final publication of Sindos’ excavations . Great care was taken in defining the stratigraphy and verifying the archaeological context of the collected samples. Accordingly, the FTIR analysis was performed on the building materials and other archaeological sediments from which the charred material for dating was collected . Where possible, later deposited sediments covering the contexts and structures to be dated were sampled in order to compare and verify the different nature of the building materials and these sediments.

At Kastanas, for example, a site in close vicinity to Sindos, some buildings were destroyed only a few years or decades after erection, whereas others (e.g. level 12) have a life-span of more than a century before being levelled for purposes of rebuilding . In contrast to the applied linear age-depth modelling, at Sindos the actual tell-formation is indeed not well-represented as series of continuous, successive, and equilength sedimentological episodes. Below is a short description of the archaeological framework of the dated contexts , combined with the results obtained through radiocarbon measurements for the dating of the specific layers. Thomas and Nelson took pains to try to falsify their own results, but some evolutionists will undoubtedly remain unsatisfied with any paper published in a creationary journal.

& Kitagawa, H. A protocol for using attenuated total reflection Fourier-transform infrared spectroscopy for pre-screening ancient bone collagen prior to radiocarbon dating. Rapid Commun. Spectrometry 34, e8720 . As cross-matching with other available regional subfossil pine reference chronologies was unsuccessful, age-estimation for samples from the two site chronologies was reliant on the results of the radiocarbon age determination.

Where all dates were nearly identical, we simply used the rounded figures . In cases where the dates within a phase varied , we used the OxCal query “Last” to determine the most probable age. The agreement of the Standard Model is 90% . A full taphonomic analysis is required in order to contextualise and thus correctly identify culturally modified bone. The sedimentary and geological context of an archaeological site affects the taphonomic signature of the faunal assemblages it contains.

Diverse variola virus strains were widespread in northern Europe in the Viking Age. Science 369, 6502 . 1021 relates to overall transatlantic activity by the Norse. Nonetheless, our findings provide a chronological anchor for further investigations into the consequences of their westernmost expansion. Our individual 14C results are consistently better than ±2.5‰ (1σ), with some averaged results better than ±1.5‰ . Our corpus of replicated measurements is consistent with statistical expectation, and no statistically significant offset (5.1 ± 7.914C yr, 1σ) was evident between the two 14C facilities involved .
