Abstract

A group of fossil mammal ichnites from the proximity of the town of Olcoz (Navarra, Ebro Basin) is described herein. The tracks occur on sandstone beds of the Mués Formation of Suevian (Early Oligocene) age. Owing to their morphology these ichnites have been assigned to artiodactyl mammals and can be compared to Entelodontipus forms. Moreover, this represents the second known finding of this ichnogenus. Among the tracks of this deposit there is a significant heterogeneity which is due to the variable penetration and displacement of the autopodes on the substrate. On Olcoz the presence of abundant ichnites that follow subparallel tracks allows the establishment of the gregarious behaviour of the producers of such tracks.
