University of Arizona radiocarbon dates, [Part] 2.
, 1959 The radiocarbon age measurements reported here were made during May 1957-May 1958. This is the final list of solid carbon dates that will appear from the laboratory, as the solid carbon method is being discontinued in favor of the carbon dioxide gas ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

International Journal of Osteoarchaeology, EarlyView.ABSTRACT The early evolutionary history of modern domestic horses (Equus caballus/Equus ferus caballus), known as the DOM2 lineage, is well documented due to numerous archaeological and ancient DNA (aDNA) studies. Although many uncertainties remain in the domestication timeline, current evidence suggests that the domestication of modern horses began in

Scottish Archaeological Internet ReportsArchaeological excavations conducted in 2017 at Grantown Road, Forres form the final phase of works on a residential development that began in 2002. The earlier works examined an area of more than 70ha and confirmed the presence of an extensive Iron Age settlement represented by ring-ditch, ring-groove, and post-ring structures, in association with ...

Past, present and future of local crop evolution
PLANTS, PEOPLE, PLANET, EarlyView.Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Bayesian evaluation of the southern hemisphere radiocarbon offset during the holocene [PDF]
, 2009 While an interhemispheric offset in atmospheric radiocarbon levels from AD 1950–950 is now well established, its existence earlier in the Holocene is less clear, with some studies reporting globally uniform 14C levels while others finding Southern ...
