Where: British Columbia, Canada (49.5° N, 124.9° W: paleocoordinates 53.4° N, 90.6° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Sphenoceramus schmidti inoceramid zone, Haslam Formation, Late/Upper Santonian (85.8 - 83.5 Ma)

• The assemblage lacks Sphenoceramus schmidti (sensu stricto) but does include examples of S. sachalinensis and S. cf. elegans and can thus be correlated with the lower, Sphenoceramus elegans Subzone, of the S. schmidti Zone of Jeletzky (1970).

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified siltstone and lithified sandstone

Size class: macrofossils

Preservation: mold/impression
