This work analyses the sedimentary and taphonomic processes that induced the selective preservation and spatial distribution of Húescar-1 bone assemblage (early Galerian). The bone fossil remains are associated with an alluvial fan system that flowed into a lacustrine area with calcareous sedimentation. The fossils show numerous scratch and abrasion marks produced during their transportation as channel lag. The remains appear in three sedimentological settings: in paleochannel filling-up sequences, in pockets built at the outlet of the channels in the lacustrine area, and scattered within calcareous silts. Nevertheless, most of them are found in the second instante. The cumulative process was attritional as pointed out by the mortality profiles of Equus altidens and could be explained by selective predation and/or seasonal bone accumulation. The notably small number of artiodactyl species, particularly in the typical foms of bush or forest habitats and the presence of amphibious forms (Hippopotamus) are indicative of an open grassland habitat. The aquatic birds represent the autochthonous component of the association. For each bone recovered severa1 variables were measured, the data obtained underwent graphic and statistical treatment that provided useful information for the site taphonomic interpretation.
