In the last few years, image treatment has been revealed as a very useful tool in ichnological analysis of deep- sea modern marine cores, increasing visibility of trace fossils and, consequently, making easier the study of some ichnological features (i.e., bioturbation index, cross-cutting relationships, ichnofabrics, etc.). However, its use on outcrop studies is less developed. In the present paper, a version of the method is applied on specimens of Zoophycos from samples of the Pacific Colombian Miocene. The treatment has improved the visibility of very important features of the trace fossil, such as the marginal tube, the minor lamellaes and their pelletoidal infilling. Additionally, the quantification of percentage of pellets has been evaluated along a major lamellae, as well as between light and dark minor lamellaes. These data are revealed as very interesting in the interpretation of Zoophycos, a very controversial trace fossil.
