Fish body part frequency is a widely used criteria to determine the cultural or natural origin of fish assemblages. Weathering is an important taphonomic process affecting elements survival. To assess the effects of this process an experiment was conducted. It`s consists on the exposure of four perch (Percichthys trucha) and sheep bones (Ovis aries) for six years. The results show that: 1) there is differential survival on body parts, not mediated by bone density; 2) in comparative terms, fish bone elements are destroyed faster than mammals. Finally, by comparing these results to those of Delta del Arroyo Vulcana 1 fish assemblages (Musters Lake, Chubut) it`s inferred a low impact of weathering, most likely by a rapid burial.
