Stratigraphy

| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Considered as Maastrichtian (Aguilera et al. 1989; Menegazzo et al. 2016) or Turonian–Santonian based on comparisons with the Adamantina Formation of southeastern Brazil (Novas et al. 2009); given that recent stratigraphic work on the Bauru Basin has argued for a late Campanian–early Maastrichtian age for the Adamantina Formation (Batezelli 2017), this age is followed here | |||||
