Within the two sequences of "red beds" of Fields (1959) were recognized seven fragmentary paleosols formed in the Miocene under contrasted to arid climates and hills of low altitude. When formed these paleosols were covered by dry biomes and they laterally coexisted with floodplains populated by trees tolerant to residual moisture on the sediment and temporary floods of great rivers.

Palabras clave : Stratigraphy; red beds; relict soils; climatic change in the past; Colombia.
