Albertogaudrya is an extinct genus of astrapotherian mammal that lived in present-day Patagonia and Salta, Argentina (25°48′S 65°24′W / 25.8°S 65.4°W, paleocoordinates 28°12′S 55°54′W / 28.2°S 55.9°W) during the Eocene (Casamayoran SALMA) 48.6 to 37.2 million years ago.[3][4][5] Fossils of Albertogaudrya have been found in the Lumbrera and Sarmiento Formations.[3] It is named after French palaeontologist Albert Gaudry.
