Albertogaudrya is an extinct genus of astrapotherian mammal that lived in present-day Salta, Argentina (25°48′S 65°24′W / 25.8°S 65.4°W / -25.8; -65.4, paleocoordinates 28°12′S 55°54′W / 28.2°S 55.9°W / -28.2; -55.9) 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.

Species

A. carahuasensis differs from A. unica in having smaller premolars, with m1 having longer talonid and wider trigonid, p3-m1 with shallower external sulcu and lacking cingulae, and less curved hypolyphid.[3] A. carahuasensis is known from a fragmentary mandible.[6]
