Where: Argentina (30.3° S, 68.8° W: paleocoordinates 57.2° S, 118.3° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Los Espejos Formation, Pridoli to Pridoli (423.0 - 393.3 Ma)

• Upper part of formation. Authors interpret age as Pridolian. Edgecombe et al. (1994, PBDB ref. 7141 think it is Lower Lochkovian on the basis of trilobites and presence of Pleurodictyum and typical Lower Lochkovian chitinozoans in immediately overlying beds.

• member-level stratigraphic resolution

Environment/lithology: marine; bioturbated, green, yellow mudstone and sandstone

Collection methods: Coquinas 13, 15, 16, 32 in Table 2, and list of taxa in tables 3 and 4. One additional trilobite from PBDB ref. 7141.
