Where: Yukon, Canada (64.8° N, 135.2° W: paleocoordinates 0.1° S, 41.7° W)
• coordinate stated in text
• local area-level geographic resolution
When: Monograptus yukonensis graptolite zone, Road River Formation, Pragian (410.8 - 407.6 Ma)
• Lenz (1977) tentatively assigns this part of the section to the Early Pragian; however, he later (in Frýda, Blodgett & Lenz 2002) calls it Middle Pragian. Brachiopod biozone: Davidsoniatrypa johnsoni; Conodont biozone: Spathognathodus sulcatus; Graptolite biozone: Monograptus yukonensis.
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified carbonate and lithified shale
Size class: macrofossils
Preservation: replaced with silica
Reposited in the GSC
• Lenz's 655'-675' is taken to be equivalent, as there is no other subsection in Lenz (1977) that overlaps with this. It likely was remeasured in the subsequent 25 years. This list is a portion of collection 24933 from Lenz 1999, which is an overview of these collections.
