We had analyzed the beginning of the teaching of Geology in 1865 at the University of Buenos Aires. Years later, in 1906, with the creation of the National University of La Plata, the teaching of geological sciences began at the Museum of La Plata, with Walther Schiller and Santiago Roth, with courses in Geology and Paleontology. In the 1930s, Joaquín Frenguelli and Enrico Fossa Mancini joined, which coincided with an explosion in the enrollment of Geology students given the boost that oil exploration produced in the country. The creation of the Faculty of Natural Sciences and Museum in 1949 consolidated the teaching together with new professors such as Mario Teruggi, Rosendo Pascual, and Alfredo Cuerda. In Buenos Aires, the school of geology was consolidated in 1922 with the arrival first of Hans Keidel as professor and later with Pablo Groeber. Both contributed to the training of human resources, among which Horacio Harrington stood out with his studies of the Flora of Glossopteris and his connection to the Gondwana continent, who was a strong promoter of Continental Drift. Harrington's return to the country after his second doctorate at Oxford University allowed the curricula to be updated. Together with Armando Leanza, they created the Institute of Geology of the University of Buenos Aires, which concentrated on excellent research and teaching. At the University of Córdoba, where the Doctorate in Natural Sciences was founded in 1876, it gradually disappeared until its reinstatement in 1918. Bodenbender started teaching again in 1919 and together with Oskar Schmieder, Roberto Beder, and Anselm Windhausen consolidated the courses in Natural Sciences. In the 1940s, Juan Olsacher and Otto Schlagintweit were in charge of teaching.
