Where: Spain (43.5° N, 5.3° W: paleocoordinates 31.7° N, 3.2° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Solis Member (Gijon Formation), Planorbis (201.3 - 196.5 Ma)

• Presence of Psiloceras sp. suggests early Hettangian age.

• bed-level stratigraphic resolution
