Commotion Composite (Cretaceous to of Canada)

Also known as Commotion Creek

Where: British Columbia, Canada (55.5° N, 122.0° W: paleocoordinates 57.1° N, 73.7° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Commotion Formation, Late/Upper Albian to Late/Upper Albian (105.3 - 93.9 Ma)

• Commotion is stratigraphically over the Moosebar Formation of shale and sandstone and it is under the Hasler Formation of predominant shale. Plant fossils are from the top 180 feet of the the 1300-1500 foot thick Commotion Formation.

• member-level stratigraphic resolution

Environment/lithology: terrestrial; carbonaceous sandstone and carbonaceous shale

• plant fossils are from beds of sandstone, shale, and some intercalated coal above a prominent bed of chert-pebble conglomerate.

Collection methods: quarrying, surface (float), surface (in situ), mechanical,
