| Formation: | Ischigualasto | Member: | Cancha de Bochas | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: ~100 m above the base of the formation according to Cox (1965). This would place the locality within the "Scaphonyx-Exaeretodon-Herrerasaurus biozone" of Martinez et al. (2011: Science 331: 206) which reportedly represents "a narrow temporal interval from 231.5 to 229 Ma in the latter half of the Carnian stage".
5 specimens from "about" the same horizon (Cox 1965). | |||||
