Where: Argentina (30.3° S, 68.8° W: paleocoordinates 45.0° S, 129.9° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Los Espejos Formation, Wenlock to Wenlock (433.4 - 419.2 Ma)
• formation-level stratigraphic resolution
Environment/lithology: marine; sandstone and bioturbated mudstone
Collection methods: Table 2. This formation-level list is included because not all faunal elements in table 2 are listed in separate facies-specific lists (collections 25053-25057).
