Kalbak-Kyry, Tuva (Jurassic of Russian Federation)

Where: Tuva, Russian Federation (51.7° N, 94.3° E: paleocoordinates 53.6° N, 93.8° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Saldam Formation, Late/Upper Jurassic (163.5 - 145.0 Ma)

• uppermost member (unnamed) of Saldam Formation

• member-level stratigraphic resolution

Environment/lithology: terrestrial; concretionary, gray, green, calcareous siltstone and fine-grained, brown, gray, argillaceous limestone

• "alternation of continental and basin cycles. The former are represented by fluviatile, delta-proluvial, lacustrine-swampy, and facies of peat bogs; the latter, by shallow and deep-water facies."

•"formed by intense fault-block movements"

• "the deposits are represented by alternating greenish gray siltstone, fine and medium-grained polymictic sandstone...a linestone lens (100 x 50 x 0.3 m) was found in an interbed of green siltstone. The rock is inactive, dark gray with a brownish tint, dense, fine-grained, clayey limestone...Siltstone is strongly fractured, easily disintegrates into gravel, and contains numerous dense carbonate concretions (1-7 cm). The latter and the overlying limestone contain isolated fine inclusions (01.-1 cm) of colorless, white, and orange strontium-containing barite. The siltstone bed is the main bone-bearing layer."

Size class: macrofossils
