The site is found in Préjamo and includes a rock surface from the Aptian period, on the slope of the Los Lobos ravine. There are seven fossil tracks, the first four very well preserved. The tracks average around 60 centimeters long and are rounded. They are the tracks of a large ornithopod iguanodontid, with a foot specially conceived to support great weight.  The other, less-defined tracks belong to medium to large-sized theropods.
