Where: Spain (42.3° N, 0.3° W: paleocoordinates 40.5° N, 3.6° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Arguis Formation, Bartonian (41.3 - 38.0 Ma)

• The Arguis Formation (latest Lutetian-early Priabonian) consists of four deepening-shallowing third-order sequences, I to IV (Millán et al. 1994). Specifically, the paguroids described come from prodeltaic sandstone found in the lower part of Sequence II as described by Millán et al. (1994). The late Bartonian age of Sequence II is well constrained by magnetostratigraphical and palaeontological data (Pueyo et al. 2002; Silva-Casal et al. 2019).
