Where: Aveiro, Portugal (40.4° N, 8.4° W: paleocoordinates 5.3° S, 8.0° E)

When: Vale da Mó Formation, Gzhelian (303.7 - 298.9 Ma)

• S. Pereira (pers. comm 2022): "currently the beds no longer outcrop (the house was under construction at the time the specimen was found, and paths and gardens have been made, nothing outcrops within that area of the house). In stratigraphic terms, although I cannot guarantee it, the specimen should come from the Vale da Mó Formation (see Wagner et al., 1983 and Machado et al., 2018, Geobios 832), because a few metres stratigraphically below, outcrops the Algeriz Formation, still exposed on the main road, and in the alignment of this locality 1km to SE, it is the Vale da Mó Fm that outcrops. "

Environment/lithology: lacustrine; lithology not reported
