In 1925, the German paleontologist Dr. Bruno von Freyberg, University of Halle-Wittenberg, visited the site. That same year Dr. G. Florence and Pacheco of the "Geological and geographical Commission of Sao Paulo" were in place. In 1927, Guilherme Rau collected the cynodont "Gomphodontosuchus brasiliensis". In 1927, geologists Paulino Franco de Carvalho and Nero Passos visited Santa Maria. This year also the geologist Alex Löfgren joined, who was here for a year and a half, helped by Munari. In 1928 the German paleontologist Friedrich von Huene visited the area, accompanied by Dr. Rudolf Stahlecker. They spent six months at the site and returned to Germany with many tons of fossils. Many fossils that were collected are housed at the University of Tübingen, Germany. During this period had been staying at the home of Guilherme Hübner, located within the site. Fossils of "Cerritosaurus" were collected in 1941 by the Jesuit Antonio Binsfeld, of "Seminary São José" in Santa Maria. In the 1940s and 1950s, expeditions organized by Llewellyn Ivor Price, the "Division of Paleontology at the National Department of Mineral Production" of Rio de Janeiro, arriving in the region. Price has worked in the area along with Edwin Harris Colbert, Carlos de Paula Couto, Mackenzie Gondon, Fausto Luis de Souza Cunha and Theodore E. White. In Santa Maria, Price stayed at Centenário College. Between 1968 and 1973, priest Daniel Cargnin collected many fossils at the site, which were sent to several research institutions and museums. In 1999, Max Cardoso Langer and colleagues collected on the spot the dinosaur "Saturnalia tupiniquim". In honor of the researchers Atílio Munari and Daniel Cargnin, streets near the site received their names. Atílio Munari's body rests in "São José Cemetery", near the site. Historically this is the most important paleontological site of Rio Grande do Sul this location was found the first fossil of Geopark Paleorrota and also the first Brazilian dinosaur Staurikosaurus and one of the oldest found on the planet. Great researchers have gone through this site and helped form the Brazilian paleontology. The site is known internationally for his outstanding contributions and is in the urban area of Santa Maria city, near a major road junction, with great handling car, and even then, there is a project to make the place a tourist spot.
