Santana formation in Brazil is the stratum in which various kinds and well preserved fossils are found. This layer which formed in early cretaceous period includes fossils of fish, amphibians, reptiles and dinosaurs. Angaturama is a kind of Spinosaurus family. The size is about 8m (27ft) in length and 2 tons in weight. Probably fish is the main prey of Angaturama. Santana formation also includes several kinds of pterosaurs such as Tapejara, Anhanguera and Tharassodromeus. Especially head of Tharassodromeus is one of the significant discoveries because of the imprints which are probably veins on the crest. Tharassodoromeus could have regulated their body temperature with those veins. Santana formation is famous for the richness of fish fossils too. Calamopleurus had scales and long body, which is about 140cm (56in) in length. Iansan is a kind of ray, which is about 50cm (20in) long.
