Where: Ukraine (44.9° N, 34.2° E)

• Paleocoordinates: 28.9° N, 48.4° E (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Illyrian (243.3 - 241.5 Ma)

• From the Taurian Series. Questionably placed in the Ladinian and compared to G. medvedevi (which was also said to come from Ladinian beds). The G. medvedevi beds are now uppermost Anisian (as are nearly all occurrences of Gymnotoceras), so that age is assigned here.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, argillaceous siltstone

Size class: macrofossils
