Where: British Columbia, Canada (50.7° N, 127.6° W: paleocoordinates 7.5° N, 119.7° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Quatsino Limestone Formation, Tuvalian (232.0 - 221.5 Ma)
• The beds sampled are descirbed as transitional between the Quatsino Limestone and the Parson Bay Formation, and are assigned to the Welleri Zone. The text describes separate faunas from a lower and an upper bed [JA: originally entered as Carnian; the Dilleri and Welleri zones are both Tuvalian according to Lucas et al. 2012]
• group of beds-level stratigraphic resolution
Environment/lithology: gray limestone and black mixed carbonate-siliciclastic
