Where: Tasmania, Australia (42.6° S, 146.5° E: paleocoordinates 9.4° N, 174.2° W)

• coordinate stated in text

• local area-level geographic resolution

When: Eoplacognathus suecicus conodont zone, Cashions Creek Formation (Gordon Group), Darriwilian (467.3 - 458.4 Ma)

• Was Llandeilo. PJW: This should be the Eoplacognathus suecicus zone.
