Cross-referenced p3k14c

This database of radiocarbon dates has been published and archived elsewhere. This version of the database has been annotated to leverage linked data resources to enhance exploration and searchability. This version also redacts samples of ancestral human remains from the United States, Canada, and Australia.

The data tables and references are also available on tDAR and a Github repository, and code for processing these data is archived with Zenodo. The database is discussed in a 2022 publication in Scientific Data (full reference below).

Description:

Archaeologists increasingly use large radiocarbon databases to model prehistoric human demography (also termed paleo-demography). Numerous independent projects, funded over the past decade, have assembled such databases from multiple regions of the world. These data provide unprecedented potential for comparative research on human population ecology and the evolution of social-ecological systems across the Earth. However, these databases have been developed using different sample selection criteria, which has resulted in interoperability issues for global-scale, comparative paleo-demographic research and integration with paleoclimate and paleoenvironmental data. We present a synthetic, global-scale archaeological radiocarbon database composed of 180,070 radiocarbon dates that have been cleaned according to a standardized sample selection criteria. This database increases the reusability of archaeological radiocarbon data and streamlines quality control assessments for various types of paleo-demographic research. As part of an assessment of data quality, we conduct two analyses of sampling bias in the global database at multiple scales. This database is ideal for paleo-demographic research focused on dates-as-data, bayesian modeling, or summed probability distribution methodologies.
