Where: Yukon, Canada (66.1° N, 140.0° W)
• Paleocoordinates: 46.5° N, 22.6° W (Wright 2013)
• coordinate stated in text
• basin-level geographic resolution
When: Tahkandit Formation, Roadian to Roadian (272.3 - 264.3 Ma)
• The time interval given by the authors is Leonardian and ? Guadalupian. The Permo-Pennsylvanian in the northern Yukon is ideally divided into three units called, in ascending order: Lower Limestone unit, Middle Recessive unit, and Tahkandit Formation (Nelson, 1961a, b, 1962b).
Environment/lithology: marine; limestone and cherty/siliceous limestone
Size class: macrofossils
Collection methods: Authors counted brachiopods only, but listed other taxa present. Fossils were collected from 14 horizons in the Tahkandit Formation, but the horizons are not labeled in Text-Fig. 2 or listed elsewhere in the article.
