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. [4] [5] [6] Fossils of Albertogaudrya have been found in the Lumbrera and Sarmiento Formations. [4] It is named after French palaeontologist Albert Gaudry.
A. carahuasensis differs from A. unica in having smaller premolars, with m1 having longer talonid and wider trigonid, p3-m1 with shallower external sulci and lacking cingulae, and less curved hypolophid. [3] A. carahuasensis is known from a fragmentary mandible. [6]
