Kurusu (KU) Section, Inuyama, KU (e) 3 (Triassic of Japan)

Where: Japan (35.4° N, 137.0° E: paleocoordinates 45.1° N, 132.8° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Canoptum triassicum assemblage-zone zone, Late/Upper Triassic (237.0 - 201.4 Ma)

Environment/lithology: marine; lithified, gray, green, red chert and lithified mudstone

• This section is composed of a rhythmically interbedded sequence of chert and mudstone. The thickness of individual chert layer varies from 1 to 7 cm (mostly 4-4,5 cm), and the mudstone layer is very thin (mostly 1-3mm).

•The chert exhibits a wide range of color, varying from mostly gray and green to partly red. In these chert layers, some sedimentary structures such as convolute lamination are observed.

Size class: microfossils
