4E594A78540DFFD997D7F9FEFDB4FE2F.taxon	materials_examined	HOLOTYPE: MML-PV- 42. Right maxilla preserving 10 teeth with different degrees of completeness. The fossil material is threedimensional and tooth enamel and wear facets are well preserved.	en	APESTEGUÍA, SEBASTIÁN, ROUGIER, GUILLERMO W. (2007): A Late Campanian Sphenodontid Maxilla from Northern Patagonia.

4E594A78540DFFD997D7F9FEFDB4FE2F.taxon	etymology	ETYMOLOGY: Lamarque after the city of Lamarque in Rio Negro province and its inhabitants, who have strongly supported paleontological exploration of northern Patagonia for decades; saurus, Greek for ‘‘ reptile’ ’; and Cabaza, after Tito Cabaza, amateur paleontologist who discovered the Cerro Tortuga locality and called the attention of professional paleontologists to the region. LOCALITY AND HORIZON: Lower to middle part of Allen Formation, ca. 6 m from the base levels of exposures at the ‘‘ Cerro Tortuga’ ’ locality (39 ° 26 9 50 0 S, 67 ° 19 9 20 0 W) and ca. 52 m below the K / T (Cretaceous- Tertiary) boundary, recognized in the overlying Jagüel Formation (Gasparini et al., 2003; Casadío, personal commun.) The fossiliferous layer is 60 – 65 cm thick and is composed of clean, yellowish to light brown, friable medium sandstone. The layer yields a rich collection of disarticulated fossils with a clear bias to small specimens; fish and snake remains are particularly abundant.	en	APESTEGUÍA, SEBASTIÁN, ROUGIER, GUILLERMO W.

4E594A78540DFFD997D7F9FEFDB4FE2F.taxon	diagnosis	DIAGNOSIS: Sphenodontid with the following combination of features: additional teeth separated by wide spaces; strongly concave maxilla; anterolingual flanges and shallow lateral ridges in maxillary teeth; labial border splits in two portions (fig. 2, sdf); antorbital region of the labial border deeply furrowed (fig. 2, rar); and deep concavities in the maxillary dentina over the third and fifth tooth positions (the last three characters are possibly uniquely derived features).	en	APESTEGUÍA, SEBASTIÁN, ROUGIER, GUILLERMO W.
