Where: La Rioja, Argentina (29.1° S, 69.1° W: paleocoordinates 45.8° S, 34.9° W)
• coordinate estimated from map
• small collection-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).
• bed-level stratigraphic resolution
Environment/lithology: lacustrine - large; lithified, fine-grained, volcaniclastic, green sandstone
•Ichigualasto–Villa Unión Basin, developed along the western Gondwana margin associated with extension focused along the northwest-trending Paleozoic sutures. 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
Preservation: mold/impression
Collection methods: surface (in situ),
