The aim of this presentation is to discuss the different views about paleosol classification and give some examples of the current knowledge in Argentina. Literature about paleosols is abundant but there is not any paleosol classification totally accepted and widely used. Several classification systems for paleosols have been developed recently based on the US Soil Taxonomy and the World Reference Base for Soil Resources used for modern soils, but their use is still very limited. Some of them are applied to buried soils and the others to all kind of paleosols. The Soil Taxonomy (Soil Survey Staff, 1999) is the soil classification system used in Argentina for present soils. In soil maps we use an extended concept of the "thapto concept" taken from that classification and applied to shallow buried soils. On the other hand, there is not any conceptual discussion about paleosols classification from the paleopedological point of view in Argentina.
