Fig. 1. A in A new Mississippian hexactinellid sponge from the western Gondwana: Taxonomic and paleobiogeographic implications

Fig. 1. A. Geographic location of the studied area. B. Geological map and location of the studied section. The west flank of the Agua Quemada Syncline is divided in some tectonic blocks (1 and 2) by inverse and dextral strip faults. Sponges come from nodules of equivalent fine-grained dark stratigraphical intervals of the Agua de Lucho Formation (Tournaisian), cropping out under glacigenic diamictitic in both tectonic blocks. C. Stratigraphic column of the Agua de Lucho Formation and the location of the sponge-bearing levels.
