Stratigraphy
| Formation: | Petaca |
Lithology and environment
| Primary lithology: | massive sandstone |
| Lithology description: The fossil remains were found within the sandy beds (Fig. 3B). The deposits of this unit consist of tabular to lenticular bodies with erosive bases, 0.5–7 m thick, and lateral extensions between 50–150 m (Fig. 3C). | |
| Environment: | fluvial indet. |
| Geology comments: The Petaca Formation is interpreted as interconnected flu- vial system deposits with floodplain development (Marshall et al. 1993, Uba et al. 2005, 2006, Vergani et al. 2012). | |
Taphonomy
| Modes of preservation: | body |

Collection methods and comments
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: housed in the vertebrate paleontology collection of the Yacimientos Petrolíferos Fiscales de Bolivia (YPFB, Santa Cruz de la Sierra). | |
