The use of statistical tools has been widely applied in science in general and also particulary in natural sciences. Geology and paleontology have not been the exception. Furthermore, in the beginning of ichnology, statistics have been used primarily in ichnotaxonomy, especially for the identification of ichnoespecies through morphometric measures, which it is not accepted today in the ichnotaxobase concept. In the last decades, new numerical concepts have been introduced, such as the maximum diameter of traces or the bioturbation index that have led to interpret environmental aspects, such as oxygenation and salinity. Recent sedimentological investigations, carried out in the Paleozoic of the Bolivian Subandean region, have provided new advances and applications (what is here called ?Ichnostatistics?) to unlock the paleoenvironmental distribution of trace fossils, ichnofacies and ichnolitological associations.
