Goodlands Member, Site WP9, P5065-4B (Paleocene of Canada)

Where: Manitoba, Canada (49.1° N, 100.6° W: paleocoordinates 54.0° N, 74.8° W)

• coordinate stated in text

• hand sample-level geographic resolution

When: Goodlands Member (Turtel Mountain Formation), Danian (66.0 - 61.6 Ma)

• Sample height in section estimated from Figure 4.

•Sediments from the Goodlands Member were assigned to the early Palaeocene, and two biozones - lower Wodehouseia fimbriata and upper Tricolporopollenites kruschii - were identified (Braman and Sweet, 1999).

Environment/lithology: mire or swamp; gray, carbonaceous claystone

• A forested mire with angiosperms grew in the vicinity during deposition. The sample contains palynoflora from a gymnosperm-dominated environment. Warm-adapted plants flourished in a near-shore transient terrestrial swamp environment dominated by angiosperms and conifers, that was analogous to modern swamps of the southern United States. They were deposited in coastal environments as the Western Interior seaway retreated.
• Approximately 40 cm thick and consists of dark grey carbonaceous clay.

Size class: microfossils

Preservation: original sporopollenin

Collected in 2007; reposited in the GSC

Collection methods: bulk, chemical, hydroflouric,

• Samples were processed at the palynology lab of the Geological Survey of Canada (GSC), Calgary, Alberta. Briefly, material was macerated and subjected to acid digestion to remove organic matter, carbonates and silicates. Resulting slurries were stained using Safranin ‘O’ and mounted with liquid bioplastic.

•They are stored in collections at GSC, Calgary.
