GSC C-118567, Long Island Bay (Cretaceous of Canada)

Also known as MVA(F)85-142

Where: British Columbia, Canada (49.5° N, 121.8° W: paleocoordinates 47.0° N, 68.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Buchia pacifica other zone, Peninsula Formation, Early/Lower Valanginian (140.2 - 136.4 Ma)

• Unlike specifically indeterminate Buchia of the lot C-l 18566, several Buchia of lot C-l 18567 exhibit very coarse but closely spaced concentric ornament combined with a posteriorly truncated shell shape and large dimensions. This combination of features is only known in the early Valanginian Buchia pacifica Jeletzky, 1965. Therefore, lot C-118567 is tentatively assigned to some part of Buchia pacifica Zone

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, gray phyllite

• Grey phyllite contains strongly deformed fossils

Size class: macrofossils

Reposited in the GSC
