PBDB Collection

Brachiopods of the Pragian of Royal Creek, Yukon (Devonian of Canada)

Also known as Vagrania-Thliborhynchia Community

Where: Yukon, Canada (65.0° N, 135.0° W: paleocoordinates 0.1° S, 41.5° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Road River Group, Pragian (410.8 - 407.6 Ma)

• Pragian (140-260 m of section 1 and 250-360 m of section 2).

Environment/lithology: slope; carbonate and siliciclastic

• "Essentially the same as the older Spirigerina-Ancillotoechia Community discussed herein", to wit:

•"This community is everywhere typically found in deep water, basin-slope deposits. Debris flows are common, and gbraded beds may be present. A relatively deep and quiet water setting is proposed...Probably intergrades with the slightly shallower (BA 3) Atrypa-Gypidula community."

•SEP environmental call based on given info. and regional context

• Elsewhere (Lenz 1982, PBDB ref. 7001), this sequence is described as consisting of mixed basinal carbonates and clastics.

Collection methods: "Bulk faunal composition." Brachiopods are assigned to five abundance categories.
