Plagiodontes daedaleus ( Deshayes 1851) is an endemic gasteropod from Sierras Pampeanas found in continental Quaternary sediments. Its distribution and endemism is related to mountain ranges, being widespread in the mountainous region of Córdoba. Due to the considerable amount of well-preserved shells of this species found in the archaeological excavations associated with to one of the occupations in the Alero Deodoro Roca site, dated 3043 + 41 years BP ( MTC14144, vegetal charcoal ) . ( Valle de Ongamira ) , we considered this taxon for classical morphometric analysis of their exoskeleton. From this, we proceeded to evaluate whether there were differences in the shape and size of the shells by comparing fossil ( N=72) and recent samples ( N=90) collected from the study area, in order to recognize morphometric variability over time linked to environmental changes occurred in the recent past. Five linear measurements, two angular measurements and four proportions between these variables were performed. Data were analyzed through statistical methods, previously expressed in terms of natural logarithm. Results would indicate that environmental changes are not reflected in the classic or linear morphometry for this taxon.
