Also known as Sphagesaurus montealtensis type, MPMA 15

Where: São Paulo, Brazil (21.3° S, 48.5° W: paleocoordinates 25.6° S, 31.5° W)

• coordinate estimated from map

When: Adamantina Formation (Bauru Group), Late/Upper Campanian to Late/Upper Campanian (83.5 - 66.0 Ma)

• Whereas a Turonian–Santonian age for the Adamantina Formation, based on ostracods and charophytes, has been proposed (Dias-Brito et al. 2001), other authors have argued for a Campanian–Maastrichtian age, based on vertebrate fossils and an alternative interpretation of the ostracod fauna (e.g. Gobbo-Rodrigues et al. 1999; Fernandes and Coimbra 2000). Most recently, stratigraphic work on the Bauru Basin has argued for a late Campanian–early Maastrichtian age for this stratigraphic unit (Batezelli 2017).

• bed-level stratigraphic resolution
