Where: Russian Federation (54.2° N, 48.4° E: paleocoordinates 47.7° N, 50.5° E)

• coordinate stated in text

• local area-level geographic resolution

Size class: macrofossils

Preservation: recrystallized, replaced with silica

Collection methods: quarrying, surface (float), surface (in situ),

• Figured material is deposited in the Museum of the Earth of the Moscow State University, Russia (MSU); some material is also reposited in the Dept of Geology and Paleontology at the University of Hannover, Germany (SGPI).
