Abstract


The results of the taphonomic analysis of the fossil remains
discovered in the paleontological site "Kamac Mayu" (Región de Antofagasta, Chile) are presented.
The paleofaunistic record, represented by Macrauchenia cf. M. patachonica, Hippidion saldiasi, Camelidae
and Xenarthra, was found in an exocarstic formation originated by dissolution, moulded over the superior
share of loam deposits and filled up with pebbly sandstone and sandstone. The bone accumulation in
the channel, suggests a depositacional scenario of natural deaths originated upstream from an old system
of drained lake formations, being the fossil remains dragged differentially and deposited dowstream. The
presence of Macrauchenia cf. M. patachonica and Hippidion saldiasi, suggests a late Pleistocene age for the sediments
