The samples will be taken from the paleosol that are under the layer of footprints, another sample of the paleosol that will look for elements of organic carbon remains through C14 and another sample for the OSL and C14 of the layer that protrudes over the footprints. .

These tests will be carried out on site in full darkness and will be taken to laboratories in the United States and the results will be in May of next year 2017.
