This hiatus coincides with the H1 eruption. Also, archaeological studies showedvariations in the technological set recorded before and after the H1 eruption.Thus, we hope to be able to identify if there were changes in microfossils frecuencyand if it could be associated to changes in paleodiet before and after of the H1eruptionModern faeces were collected from the two different sites: Cueva Milodón Norte 1 (A) and Salitroso (B) during spring 2019. The extraction of the proxies was carried out following the reference protocols. The material was mounted on slides for observation under an optical microscope. The plant fragments were determined by comparison with reference of specimens collected in the study areaThe reference models were reached through the joint analysis of the three proxies.-The multiproxy analysis of the feces allowed to differentiate different feeding sites of the guanacos.-The reference models will allow the interpretation of the results of the multiproxy analysis ofholocenic coproliteshttps://www.researchgate.net/publication/354048048_EAA_2021_Program_12th_International_Meeting_for_Phytolith_Research_7-11_September_2021_online
