"From an ichnological point of view, the Larache footprints represent an important discovery. Indeed, no other site in North Africa has yielded footprints dating from the Pleistocene or Pliocene. They are, therefore, the oldest human footprints in this region and among the oldest footprints attributed to Homo sapiens worldwide."
From google : Ichnology is the study of the fossilized tracks, trails, burrows and excavations made by animals and more broadly the study of bioturbation, which is the reworking of sediment by animals. Ichnologists use ichnofossils or trace fossils to interpret paleoecological aspects of sedimentary environments.
