Some carnivorous mammals ingest fruit and disperse seeds of forest plant species capable of colonizing disturbed areas in ecosystems. The objective of the study was to evaluate the dissemination of Arctostaphylos pungens and Juniperus deppeana seeds by the grey fox (Urocyon cinereoargenteus), coyote (Canis latrans) and other carnivores in the Protected Natural Area Sierra Fría, in Aguascalientes, Mexico. Scat collection was undertaken via transects using the direct search method. The dataset contains the geographical coordinates in UTM format of the location of each of the mammalian scats found. During the study, it was possible to find scats of four species of mammals: grey fox, coyote, ringtail (Bassariscus astutus) and bobcat (Lynx rufus), therefore, for each species, a different Excel file containing the coordinates of each scat found is presented separately. It is worth mentioning that each coordinate corresponds to each scat, so some coordinates are repeated, because several scats were found in the same site forming latrines.
