Where: Morocco (33.5° N, 7.2° W: paleocoordinates 59.0° S, 21.4° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Ben Slimane Kalkknollen Formation, Late/Upper Lochkovian (414.0 - 410.8 Ma)

• Latest Lochkovian, based on faunal content such as nowakiids. Given as Kalkknollen in Bault et al. (2021); however, as Kalkknollen is used for other rock units elsewhere, I have modified it with Ben Slimane.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; black limestone

Size class: macrofossils

Collection methods: P. 8 of ref. 7487 and column 11 of table 3 of ref. 7485.
