Syncrude Base Mine, West side II (Cretaceous of Canada)

Also known as TMP 99.68.01 elasmosaurid site

Where: Alberta, Canada (57.0° N, 111.7° W: paleocoordinates 56.4° N, 57.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Wabiskaw Member (Clearwater Formation), Early/Lower Albian (112.0 - 109.0 Ma)

• Lower Albian age based on angiosperm palynomorphs and Foraminifera

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; medium, glauconitic sandstone

• 2-3 metre thick, heterolithic, very fine- to medium-grained glauconitic sandstone unit... deposition of the uniti in which TMP 98.49.02 was found occured under fully marine conditions, as demonstrated by its laterally extensive deposits, trace fossil assemblages, and sedimentology... facies analysis of cores from the region around the type locality...suggests that deposition of the fossil-bearing unit occured in the lower shoreface-offshore transition zone.

Size class: macrofossils

Collected by Syncrude, Canada in ?1992-2006; reposited in the TMP

Collection methods: quarrying

• Oil sand mining
