Where: Fukuoka, Japan (33.8° N, 130.9° E: paleocoordinates 41.1° N, 132.6° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Third Formation (Wakino Group), Neocomian (145.0 - 125.8 Ma)

• The fourth formation (the uppermost formation, W4) correlates to the Upper Wakamiya Formation. The thickness is around 250m. The basal part consists of a conglomerate of white chert and unconformably or conformably overlies the third formation.

Environment/lithology: terrestrial; lithified sandstone and lithified shale

Size class: macrofossils

Preservation: adpression

Collection methods: chemical, peel or thin section

• All fossil specimens used in the present study are deposited in the Kitakyushu Museum and Institute of Natural History (NMNH)

•

•Some specimens were immersed in a bath of 20% HCl and 80% water in 24-48 hours to etch their bones. Latex peels were made from the etched fossils for observation.

•

•The outline of large specimens were drawn by tracing the enlarged positive films and detailed drawings were made with a binocular microscope.
