Calcareous Rock Marine Fossils from Spain (Catalunya / Costa Brava / Altafulla - Torredembarra Region) collected between 1966 and 1981

Neo-Fossil-bearing marine sediment fragments from Costa Brava tidal zone limestone cliffs at Altafulla Torredembarra. The stepwise ongoing mineralization process under sunlight, heat and periodic salt-water influence as factors of petrification / fossilization is visible clearly in the salt cristal layer on the turret snail.
