MesoRAD:  A Radiocarbon Database for Archaeological and Isotopic Research in Mesoamerica

The Mesoamerican Radiocarbon (MesoRAD) database compiles radiocarbon dates and isotopic data from archaeological sites in across Mesoamerica. Mesoamerica as a culture region is defined by shared cultural traits that span the areas of northern, central, and southern Mexico, Belize, Guatemala, Honduras, and parts of El Salvador and Nicaragua (see map above). In its final form, we hope that the database can be  used as an open-access repository that will facilitate collaborative studies in the future.

In its current form, MesoRAD is a compilation of published radiocarbon dates from the Maya lowlands. However, we are interested in expanding the regional breadth of the database. If you are interested in helping the database managers in these endeavors, we would love to hear from you!

We have worked with tDAR to archive these data for future use, allowing anyone who uses the data to cite the database with its attached DOI.  You can find the most recent version of MesoRad here:
