The photo above showing dinosaur footprints on a limestone slab was taken in the Fumanya Coal Mine, near the city of Berga (Catalogna) in northern Spain. This large surface layer of Maestrichtian (upper Cretaceous) lacustrine limestone was exposed during mining activity. Fumanya Mine is located in the southern Pyrenees Mountains. The numerous alignments of rounded traces which can be observed here are tracks of dinosaur footprints. Given the size and the general shape of their footprints, these animals were probably sauropods -- large plant eating dinosaurs. Note also the superb network of small- scale offset faults that crosscut the structural surface. The photo was taken on March 18, 2005.
