Maude Island, west of Ells Bay; GSC loc. C-304569 (Jurassic of Canada)

Where: British Columbia, Canada (53.2° N, 132.0° W: paleocoordinates 2.3° N, 126.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Freboldi ammonoid zone, Rennel Junction Member (Fannin Formation), Early/Lower Pliensbachian (189.6 - 183.0 Ma)

• Sample from limestone concretion 76.5 m above base of section

Environment/lithology: marine; concretionary limestone

• At base, the Ghost Creek Formation (46 m) is thick bedded dark grey shale with rare limestone concretions and lenses; the overlying Rennell Junction member of the Fannin Formation (~37 m) is comprised mainly medium to thick bedded dark grey siliceous siltstone, minor shale and sandstone with abundant limestone concretions; the upper beds of the Fannin Formation (~30 m) are much more sandy and contain only rare limestone lenses

Size class: microfossils
