The files in this package include data files and R Markdown analyses scripts for the published paper: 

GA Clark, CM Barton, and LG Straus (2018) Landscapes, Climate Change & Forager Mobility in the Upper Paleolithic of Northern Spain. Quaternary International.

This data and analysis package should be cited as:

Barton, C.M., Clark, G.A., Straus, L.G., 2018. Upper Paleolithic of N Spain - Lithic and C14 Data and Analysis. https://zenodo.org/record/[zenodo DOI number].

You are welcome to use these data in scientific research but you should cite both the paper and this dataset. 

IMPORTANT CLARIFICATION: The data published here represent the data used for our analysis, extracted from published sources, matched to global DEMs. They should not be considered a gazeteer for geographically relocating individual archaeological sites (though others are welcome to use our data as a starting point for such a gazeteer). Moreover, sites represent single localities, within a region occupied by prehistoric groups, where people occasionally left material remains of their activities and which archaeologists happen to know about. Hence, for the purposes of studies like this one, site locations should be considered to be an imperfect, point sample of a regional occupation.

This package contains:
