Taphonomic modes on fluvial deposits of the Monte Hermoso Formation (early Pliocene), Buenos Aires province, Argentina
The sedimentary deposits of the Monte Hermoso Formation, outcropping at its type locality (Farola Monte Hermoso, Buenos Aires province, Argentina), accumulated through fluvial processes acting on highly sinuous rivers. The Monte Hermoso Formation comprises a rich vertebrate fauna corresponding to th...

The sedimentary deposits of the Monte Hermoso Formation, outcropping at its type locality (Farola Monte Hermoso, Buenos Aires province, Argentina), accumulated through fluvial processes acting on highly sinuous rivers.

Comparative taphonomic analysis indicated that the faunal assemblages coming from two different fossiliferous levels, FL 1 and FL 2, recognized in floodplain deposits and channel deposits respectively, are composed of remains affected by diverse taphonomic processes and therefore representing distinct taphonomic histories. The variations recorded between both fossiliferous levels, with respect to their taphonomic attributes and sedimentary context, allowed the recognition of two distinct taphonomic modes: floodplain in the FL 1 and channel-lag in the FL 2.
