The starch grains present in the dental calculus of four Neolithic individuals of the Dehesilla Cave (Cadiz, South of Spain) were extracted and observed with light microscopy. The variant of the extraction technique used proved to be very effective. A number of Poaceae-Triticeae taxa [wheat (Triticum sp., the main crop, including Triticum aestivum), barley (Hordeum sp.)], Fabaceae-Fabeae-Cicereae and Fagaceae (oaks = Quercus sp., which constitute new data for the area in question) were identified. Some pollen grains and fungal spores were also identified, which helped to provide information on the ecological framework of the crops associated with the archaeological site.

提取德赫西拉洞穴（西班牙南部加的斯）四名新石器时代个体的牙结石中存在的淀粉粒，并用光学显微镜进行观察。事实证明，所使用的提取技术的变体非常有效。一些禾本科-小麦科类群[小麦（Triticum sp.，主要作物，包括普通小麦）、大麦（Hordeum sp.）]、豆科植物-豆科植物-西塞雷科（Fabaceae-Fabae-Cicereae）和壳斗科（橡树=  Quercus sp.），构成了新数据所涉及的区域）已被确定。还鉴定出了一些花粉粒和真菌孢子，这有助于提供与考古遗址相关的农作物生态框架的信息。
