emedyd {rcarbon}

Radiocarbon dates for the Eastern Mediterranean around the Younger Dryas

Description

Radiocarbon dates (n=1915) and site coordinates (n=201) from a paper considering the relationship between human activity in the eastern Mediterranean/Middle East and early Holocene climate change, including the Younger Dryas.

Usage

emedyd

Format

A data.frame with the following variables:

LabID

Laboratory ID assigned to each radiocarbon date (where known)

CRA

Radiocarbon age in 14C years BP

Error

Radiocarbon age error

Material

Material of the dated sample

Species

Species of the dated sample (where identified)

SiteName

Name of the site from which the sample has been recovered

Country

Country where the sampling site is located

Longitude

Longitude of the sampling site in decimal degrees

Latitude

Latitude of the sampling site in decimal degrees

Region

One of three analytical regions (1=southern Levant, 2=Northern Levant, 3= South-central Anatolia
