Also known as Sieberella cf. weberi-Nymphorhynchia pseudolivonica unit of Lenz (1968)
Where: Yukon Territory, Canada (64.8° N, 135.2° W: paleocoordinates 1.9° S, 40.5° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Early/Lower Emsian (409.1 - 402.5 Ma)
• Lenz correlates with "some portion of the lower Zlichovian"
• group of beds-level stratigraphic resolution
Environment/lithology: offshore shelf; limestone
•SEP environmental call based on given info and regional context
Size class: macrofossils
Collection methods: Abundances are given (table 1). See PBDB collections 24931, 24932, and 24933 for Lower Lochkovian, Upper Lochkovian, and Pragian lists, taken from Lenz (1999, PBDB ref. 6991), but evidently extracted from this monograph. Systematic treatment is spread over two monographs (PBDB refs. 7341 and 7342), but entire lists are given in this part (ref. 7341).
