Zaragoza/Spain — A piece of research has applied standard geological techniques and methods at an architectural site in Zaragoza to establish the diet of individuals. This piece of work is part of the PhD thesis being written up by the geologist Iranzu Laura Guede about diet and mobility in the medieval period in the north of the Iberian Peninsula.

Excavations carried out in this municipality uncovered the skeletons of 44 Muslim individuals who lived between the 8th and 10th centuries. On the basis of this discovery, a research group from the UPV/EHU's Department of Mineralogy and Petrology in the Geology Section analysed dental samples of these human remains to establish the diet of this medieval Muslim community. The study has applied techniques such as laser ablation, which are usually applied in Geology.
