Vertebrate Fauna
The Caturrita Formation contains a biozone for tetrapods, the so-called “Ictidosauria Assemblage Zone″ Ca-1.Ictidosaurs are trithelodontid cynodonts, a sister group of the mammals. This is the reason, why this biozone recently has been renamed as “Mammaliamorpha Cenozone” to underline the importance of the cynodont fossils. The Caturrita Formation also hosts the stratigraphic marker level “Jachaleria” named after the dicynodont Jachaleria candelariensis. Dinosaurs and other vertebrates have been discovered as well.
In 1998 tracks of prosauropods have been found near Faxinal do Soturno that were most likely caused by Unaysaurus tolentinoi.
The fossil finds are concentrated around three major areas: Santa Maria and northern surroundings (Água Negra) Faxinal do Soturno Candelária and surroundings (Linha São Luis)

Famous quotes containing the word fauna:
“The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man’s thoughts.”
—Louis Aragon (1897–1982)
