Where: British Columbia, Canada (55.9° N, 120.2° W: paleocoordinates 60.5° N, 77.0° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Howard Creek Member (Kaskapau Formation), Turonian to Turonian (93.9 - 86.3 Ma)
• STRATIGRAPHIC RELATIONS: The Howard Creek sandstones apparently grade laterally into siltstone and shale southward (Stott, 1968). The unit lies within marine shale of the Kaskapau and was included as part of the Sunkay Member by Stott (1967, 1968). Basal beds of the Kaskapau Formation apparently grade westerly and northwesterly into deltaic sandstone included in the Dunvegan Formation (Stelck and Wall, 1955; Stelck, 1962; Stott, 1968; Singh, 1983). AGE: Late Cenomanian, on the basis of ammonoid and foraminiferal biostratigraphy; placed in Turonian-Coniacian by the enterer based on more recent biostratigraphy. STRATIGRAPHIC POSITION: From unknown position in local section.
