Kaseki-kabe (facies II), Shiramine (Cretaceous of Japan)

Also known as Kasekiheki

Where: Ishikawa, Japan (36.2° N, 136.6° E: paleocoordinates 46.5° N, 138.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kuwajima Formation (Tetori Group), Barremian (129.4 - 125.0 Ma)

• "upper horizon" of Kuwajima Formation, uppermost part of Itoshiro Subgroup, Tetori Group. Described as "lower Neocomian", and older that "late Barremian", but authors' use of "Neocomian" seems to include some of the Gallic as well.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - small; gray, silty sandstone and mudstone

• "deposited in the channels of braided rivers and flood plains", specifically in a "shallow lake"
• "alternations of massive sandstones, fine-grained sandstones and mudstones"; facies II = "massive and poorly stratified. They comprise silty matrix with angular fine-grained quartz sands."

Size classes: macrofossils, mesofossils

Collected in 1997

Taxonomic list

• "Theropoda sp. C" is described as a member of the (unnamed) clade Oviraptorosauria + Therizinosauroidea. Another theropod is described as "Tetanurae", but the authors do not indicate whether this is sp. A or B. Note that the authors use "sp." for most of the unidentified species, but I have replaced most with "indet." because the groups are higher taxa, not genera (i.e. "Anura indet." instead of "Anura sp.").
