Stratigraphy
| Geological group: | Neuquén | Formation: | Bajo de la Carpa | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Locality relocated and attributed to the Bajo de la Carpa Formation (Filippi 2015), near its base (Pérez Moreno et al. 2023).
Original description: level given only as "Río Neuquén Formation", which is now a group, so formation could be either Plottier or Portezuelo. Portezuelo has been subdivided Garrido 2010) into 3 formations - unknown which equivalent here. JA: from the Río Neuquén Formation in the Neuquén Group according to Turner and Calvo 2005 MC: Rio Neuquen is a subgroup, not a formation. | |||||
