Serendipity Bog (Holocene of Canada)

Where: British Columbia, Canada (54.0° N, 131.8° W: paleocoordinates 54.0° N, 131.8° W)

• coordinate stated in text

When: Holocene (0.0 - 0.0 Ma)

• Two radiocarbon dates were obtained on this interval of the core. The first

•date of 8,470 + 90 (GSC-3568) was obtained from 2.80-2.75 m depth, and a second date of 8,400 ? 90 (GSC-3353) on the basal sand between 3.26 and 3.19 m depth. Comparison of the pollen chronology from Serendipity Bog with a pollen profile from a nearby lake indicates that the basal age is considered anomalous (Warner, 1984). An inferred age of about 9,400 years B.P. is more probably nearer the true age of the sediments below 3.15 m. Thus, the fossil sponge remains appear to span a period of about 1,000 y

Environment/lithology: mire or swamp; unlithified sandstone and peat

• a shallow, dystrophic bog lake

Size class: microfossils
