La formation de Romualdo est une formation géologique datant du Crétacé inférieur (Albien) où l'on trouve une accumulation de fossiles très bien préservés (Konservat-Lagerstätte). La partie supérieure de la formation de Santana pourrait être datée de la base du Crétacé supérieur (Cénomanien inférieur).
