Víctor Alberto Ramos (born 1945) is an Argentine geologist who has contributed to the paleogeography and plate tectonics of South America.
This proposal derives from a 2014 study based on biostratigraphy and radiometric dating of ash in the Vaca Muerta Formation in Neuquén Basin, Argentina.
[5] In Ramos' words the study would serve as a "first step" toward formally changing the age in the International Union of Geological Sciences.
[6] Ramos has proposed that the Patagonian landmass originated as an allochthonous terrane that separated from Antarctica and docked in South America 250 to 270 Ma in the Permian period.
[7] A 2014 study by Robert John Pankhurst and co-workers reject the idea of a far-travelled Patagonia claiming it is likely of parautochthonous (nearby) origin.
