Kaseki-kabe (facies I), 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: mire or swamp; coarse-grained sandstone and coal

• "deposited in the channels of braided rivers and flood plains", specifically in a "peat marsh"
• "alternations of massive sandstones, fine-grained sandstones and mudstones"; facies I = "massive and coarse-grained. They also often show well-developed parallel bedding marked by thin accumulations of numerous plant remains. The coarse-grained sandstones tend to grade into organic-rich fine-grained sandstones or coals."

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.").
