Coordinates:	36.2° North, 136.6° East (view map)
Paleocoordinates:	45.6° North, 144.0° East (Wright 2013)
Basis of coordinate:	based on nearby landmark
Geographic resolution:	outcrop

Time

Period:	Cretaceous	Epoch:	Early Cretaceous
Stage:	Barremian	10 m.y. bin:	Cretaceous 2
Key time interval:	Barremian
Age range of interval:	125.77 - 121.4 m.y. ago

Stratigraphy

Geological group:	Tetori	Formation:	Kuwajima
Stratigraphic resolution:	group of beds
Stratigraphy comments: "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.

Lithology and environment

Primary lithology:	gray silty sandstone
Secondary lithology:	mudstone
Includes fossils?	Y
Lithology description: "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."
Environment:	lacustrine - small
Geology comments: "deposited in the channels of braided rivers and flood plains", specifically in a "shallow lake"

Taphonomy

Modes of preservation:	body
Size of fossils:	macrofossils,mesofossils
Preservation of anatomical detail:	excellent
Articulated whole bodies:	some
Associated major elements:	some
Disassociated major elements:	many
Disassociated minor elements:	many
Fragmentation:	occasional

Collection methods and comments

Collection methods:	field collection
Reason for describing collection:	general faunal/floral analysis
Collection dates:	1997
Taxonomic list comments:"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.").
