Where: Hungary (46.9° N, 17.6° E: paleocoordinates 0.5° S, 30.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Köveskal Dolomite Formation, Induan (252.2 - 251.2 Ma)

• Formation originally described as Lower Triassic. More precise stratigraphic position after Haas, Budai 1999: Triassic sequence stratigraphy of the Transdanubian Range, Hungary. Geologica Carpathica 50/6, 459–475.

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; gray, calcareous marl

• THe depositional environment of the Köveskal Dolomite Formation has been referred to as a low energy inner shelf or lagoon.
• The dolomarls are usually parallely stratified, thin-bedded or laminated.
