Abstract Radiocarbon dates for samples from three buildings at Tikal, Guatemala, the lintel beams of which bear Maya hieroglyphs, are presented. These include dates recently determined at the University of California at Los Angeles and two UCLA and University of Pennsylvania inter-laboratory cross-checks. Two dates from the inner and outer portions of a sapote log have been determined in order to assess the growth rates of the logs from which the temple beams were fashioned and thereby help to… 

Correlating the Ancient Maya and Modern European Calendars with High-Precision AMS 14C Dating

A series of high-resolution AMS 14C dates on a wooden lintel collected from the Classic Period city of Tikal bearing Maya calendar dates indicate that the dates were carved on the lintel between AD 658-696, which strongly supports the Goodman-Martínez-Thompson (GMT) correlation and the hypothesis that climate change played an important role in the development and demise of this complex civilization.

UCLA Radiocarbon Dates III

The measurements reported in this list have been made in the Isotope Laboratory of the Institute of Geophysics during 1963 and are a continuation of the work reported previously (UCLA I and UCLA II).

UCLA Radiocarbon Dates IX

The measurements reported have been carried out during the first half of 1968 in the Isotope Laboratory of the Institute of Geophysics and Planetary Physics as a continuation of the UCLA date lists I

Radiocarbon Dating and Archeology in North America

There is great need, nevertheless, for the man in the laboratory to comprehend the difficulties of sample collecting and of judgement of the significance of the source of organic matter to be dated, and for the archeologist to become more familiar with the importance of the various steps in the processing of the sample and with, what is most vital, interpretation of the meaning of the numbers that appear on the counters.

Six Decades of Radiocarbon Dating in New World Archaeology 1

Radiocarbon (14C) dating provided New World archaeological research with the first continent-wide common chronometric scale that transcended the mostly relative site- and region-specific

The Contribution of Radiocarbon Dating to New World Archaeology

When introduced almost five decades ago, radiocarbon (14C) dating provided New World archaeologists with a common chronometric scale that transcended the countless site-specific and regional schemes

Dr. Elizabeth K. Ralph (5 February 1921–23 March 1993)

Problems encountered with the inaccuracies of radiocarbon dating led Beth to another pioneering task the establishment of correction factors for radiocarbon dates based on precisely dated tree rings.


The orientations of buildings at the ancient Mesoamerican temple centers of Teotihuacan, Tula, Chichen Itza, Palenque, Tikal, Copan, and Monte Alban were plotted against the past magnetic declination

The Beginnings of Radiocarbon Dating in American Antiquity: A Historical Perspective

Few archaeologists would dispute the suggestion that the introduction of 14C dating into archaeological research has had a profound influence on the way in which prehistoric studies are conducted.



New Radiocarbon Dates and the Maya Correlation Problem

Abstract Two long series of samples from Tikal, Petén, Guatemala, have been dated by the radiocarbon method for the purpose of limiting the range of possible correlations of the Maya calendar with

Radio-carbon Dates and the Mayan Correlation Problem

IN two papers published in 1956 and I9601, Linton Satterthwaite, jun., presented his interpretation of radio carbon dates obtained from wood from Temples I and IV and Structure 10 at Tikal,

UCLA Radiocarbon Dates VI

The measurements reported have been carried out during 1966 in the Isotope Laboratory of the Institute of Geophysics and Planetary Physics as a continuation of the UCLA date lists I through V.

University of Michigan Radiocarbon Dates X

A list of radiocarbon dates obtained since the preparation of Michigan list IV and the method of measurement and treatment of data are the same as described in the introductions to lists III and IV.

Abstract The question is frequently asked: How would a change in the half-life of C14 affect the Maya calendar correlations? The optimum “effective” half-life value for this era, as determined by the

It is generally accepted that the combustion of fossil fuels over the period 1860 to 1954 has produced an amount of carbon dioxide, containing no radiocarbon, that is equal to approximately 13% of
