Mario Pino Quivira is a Chilean geologist[1] specialized in geoarchaeology and sedimentology that has been involved in several studies of early human settlements in Southern Chile. Together with Tom Dillehay he led the excavation of Monte Verde near Puerto Montt where human remains estimated to be about 12,500 years old have been found, challenging the Clovis theory of the first human arrival in the Americas. Other studied sites includes the Chan-Chan settlement near Mehuín and the Gomphotherium of Osorno.
