%X several specimens of the peculiar coracoids of g. branisai (teleostei, clupeiformes) were found near tres cruces, jujuy. a taphofacies p1 of disarticulated fishes was defined there. this taphofacies is evenly distributed as a pavement of less than 1 cm of thickness. it is a monotypic, monospecific, and unimodal concentration. there is no orientation. according to the present evidence, a prolongued time of exposition in the active taphonomic zone is inferred. this allowed the disarticulation and posterior selective transportation of the coracoid bones. a decantation deposition is hypothesized because bioclasts are not oriented on the surfaces. the acumulation is considered para-autoctone. finally, the relevance of g. branisai as a stratigraphic correlation in argentina and bolivia is commented.
