Resumo
Forms called tafoni, diversified in different stages, are complex natural systems. The systematic register of their measurements is performed in order to infer relative ages and to use the results to reconstruct landscape evolution. The analysis of depth measures of the cavities developed into several tafoni demonstrates, for incipient cases in Galicia (NW of Iberian Peninsula), trends with different evolutionary trajectories. Depth measures were processed with robust statistical techniques. The development of tafoni combines linear and non-linear phases. This behaviour is related to the increase of complexity through self-organisation.
