It is claimed to do an actualistic fieldwork that could be valid to apply it to the genetic interpretation (taphonomy: biostratinomy) of paleontological deposits preserved in fluvio-lacustrine morphosystems, without the influence of biological agents that accumulate bones (as hyaenids or humans). The principal activity to develop in the ICTS-RBD considers to do an exploration by foot of certain not anthropic zones of the park, in environments next to fluvial riverbeds and flood plains, with the aim to locate and identify bone fragments belonging to large mammals (Carnivora and Artiodactyla). The intention of these explorations would be the description of a faunistic list about the large mammals that they inhabit currently in the park, in this sedimentary context. We?d work exclusively with information proceeding from those osseous remains located in surface and semi-buried, in order to analyze their representation in relation with the global list of macromammals. This could allow us to evaluate the different taxa abundance and diversity of depending on the sedimentary morphosystems of the park, associated with fluvial dynamics in the corresponding ecological context.
