Where: La Rioja, Argentina (29.9° S, 67.8° W: paleocoordinates 46.5° S, 33.2° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Los Rastros Formation (Agua de la Peña Group), Carnian (237.0 - 228.0 Ma)
• Carnian age based on radiometric constraints from underlying Chañares Formation in Marsicano et al. (2015).
• group of beds-level stratigraphic resolution

This extension originated from the breakup of Pangaea during the end of Permian and start of the Triassic. Synrift phase II - accommodation space generated by tectonic subsidence.
Size classes: macrofossils, mesofossils
• beetle specimens consist of 90% isolated elytra
Collection methods: quarrying,
• Specimens kept in PULR-I – Invertebrate Paleontological Collection, Universidad Nacional de La Rioja, Argentina
