The aims of the present study were: (1) to examine the parasite fauna found in carnivore coprolites from Cueva Huenul 1 archaeological site, located in northern Patagonia (Neuquén Province, Argentina), (2) to evaluate the role of this carnivores in the cycle of zoonotic parasites in the past, (3) to discuss the possible effect of the infections in humans that inhabit the cave during the Quaternary, and (4) to evaluate possible differences in egg measurements among layers. Several coprolites were obtained from layers dated since the Pleistocene-Holocene Transition. Faeces were whole processed, rehydrated, homogenised, and examined via light microscopy. Eggs of parasites were measured and photographed. Coprolites were assigned to a small feline. A total of 11 parasite species were found (8 nematode, 2 trematode, and 1 coccidian species). The paleoparasitological findings of this study display a great richness of parasitic species present in felines from CH1 through the Pleistocene-Holocene transition, some of them zoonotic. Early human societies that discontinuously occupied the site during the time scale studied could have been exposed to these infections. [ABSTRACT FROM AUTHOR]

South American camelids (SAC) have occupied a central role in the development of Andean societies. They are widely distributed in South America and since ancient times are an important factor in Andean economies and social and ritual life. The archaeological site Punta de Peña 4 (PP4) is located in Antofagasta de la Sierra Basin (Southern Puna of Argentina). PP4 is a rock overhang and presents a large occupational sequence (early Holocene until historic times). The aim of this contribution is to study parasite diversity and the relationship among parasites and SAC through holocenic times in the Southern Puna of Argentina. Besides, differences in parasite egg preservation in the site were discussed. A total of 65 coprolites assigned to SAC were rehydratated, homogenized, filtered, allowed to spontaneous sedimentation and examined for parasite remains. Given the morphology of the coprolites, the biogeographic origin and the presence of coccidian oocysts of Eimeria macusaniensis in some of them, a camelid origin of the coprolites is suggested. This is the first paleoparasitological study from PP4, an archaeological site of Antofagasta de la Sierra, a key region in northwestern Argentina and Central Andes. Eleven taxa of parasites were found belonging to Apicomplexa, Platyhelminthes, and Nematoda. Specific parasite species of SAC were found, such as E. macusaniensis and Lamanema chavezi/Nematodirus lamae. A remarkable finding was the presence of Moniezia sp. and Strongyloides sp. in coprolites from different levels of PP4, pointing out the presence of these genera in native artiodactyls of the region previous to the arrival of Hispanic societies. Results displayed a change in the number of parasite taxa present in SAC through time. The parasite-SAC relation through time and differences in parasite egg preservation between levels and sectors (covered and uncovered) of the site are discussed. [ABSTRACT FROM AUTHOR]
