The Miocene of the Northern Patagonia Coastline  of Chubut and Rio Negro Provinces (Argentina) is characterized by extensively distributed marine sequences developed over a shallow platform covering an area from Viedma to the Lower Valley of Rio Chubut. Strata was sedimented during the marine transgression associated to the "Patagoniense sea, contemporary to the "Paranaense sea" developed mostly in the Mesopotamia and Pampas of Northern Argentina. Marine strata are widely developed displaying an imortant array of trace fossils that provide clues to the biological diversity of the Miocene sea in the Patagonian coast, and its study will allow a closer comparison with other sections along the argentine coastline.
