Geography
| Country: | Canada | State/province: | Yukon |
| Coordinates: | 65.8° North, 138.9° West (view map) | ||
| Paleocoordinates: | 42.5° North, 25.1° West | ||
| Basis of coordinate: | stated in text | ||

Stratigraphy
| Formation: | Tahkandit | ||||
| Stratigraphy comments: 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). |
