Ezhovo Locality, PIN 1758 (Permian of Russian Federation)

Also known as Ocher Localities, Yezhovo,

Where: Perm, Russian Federation (57.8° N, 54.7° E: paleocoordinates 31.9° N, 43.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Estemmenosuchus uralensis other zone, Urzhumian (268.0 - 265.0 Ma)

• Ocher Subassemblage of the Ocher Assemblage; the terminal part of the Late Kazanian to the early part of the Early Tatarian (=Urzhumian) (Golubev 2000); Urzhumian according to Benton (2012; Geology)

• group of beds-level stratigraphic resolution

Environment/lithology: delta plain; ferruginous, red, argillaceous, muddy sandstone and argillaceous conglomerate

• "flood plain" Olson (1962)

•The sandy-argillaceous deposits containing the bones represent distributarys of the main stream within a deltaic setting. (informations are from Tchudinov, 1962)

• "Sandstone with beds of clay" Olson (1957);

•The bone-bearing section is mainly composed of fine-grained, clayey, reddish-brown, red, or orange-red, ferruginous sandstones with intercalations of claystone and inclusions of black, carbonaceous matter. Also, the section comprises conglomerates, composed of medium to small pebbles which consist of metamorphic or igneous rocks. (informations are from Tchudinov, 1962, Priroda 1962(4))

Size class: macrofossils

Preservation: concretion, recrystallized, permineralized, replaced with calcite

Reposited in the PIN
