Tree-ring dataset in Heidelberg format derived from pine (Pinus sp.) timbers of the roof structures at Jaen Cathedral (dendro code JCS) and the Colegial del Salvador church in Seville (code SCS). These samples were researched within the scope of the NWO-funded project Filling in the blanks in European dendrochronology. They are documented in the following article: Domínguez-Delmás, M., Van Daalen, S., Alejano-Monge, R., Wazny,T., 2018. Timber resources, transport and woodworking techniques in post-medieval Andalusia (Spain): Insights from dendroarchaeological research on historic roof structures. Journal of Archaeological Science 95: 64–75. https://doi.org/10.1016/j.jas.2018.05.002 This upload includes the supplementary material accompanying the article (tables with sampled elements on each building and their metadata). While most of the timbers from Jaen Cathedral are dated, only two of 71 from the Colegial are dated.If discrepancies exist between the metadata inserted in the headers of the measurements and tables uploaded here and the metadata on the article, the metadata published in the article prevails.
