Also known as Pycnonemosaurus type

Where: Mato Grosso, Brazil (15.5° S, 54.6° W: paleocoordinates 20.5° S, 33.7° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Parecis Group, Late/Upper Cretaceous (100.5 - 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).
