%X the interesting finding of a hippidion specimen in sediments referred to the guerrero member of the luj¨¢n formation (late pleistocene) in northeast buenos aires province is reported. preliminary considerations indicate that the bearing level represents a deposition environment similar to existing poorly-drained flood plains. analysis of several taphonomic characteristics (e.g. position, degree of articulation, soft tissue molds) allows considering that the specimen was incorporated through swamp-miring that also led to its death. available palaeoautoecological information for this taxon allows the possibility that the accumulation environment of this specimen was a habitat used regularly by the taxon. reconstruction of the taphonomic path of this specimen admits the assumption that at least some parts of the floodplain could have worked as swamp-miring sites. the occurrence of this taphonomic mode in the salado river basin is particularly relevant because it accounts for the relative abundance of relatively complete and well-articulated skeletons, and it also evidences possible taphonomic bias related to the frequency of use of this environment by each taxon.
