Magnolia bluff, REN sample (Pleistocene of the United States)

Where: Washington (47.7° N, 122.4° W: paleocoordinates 47.7° N, 122.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Olympia beds Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• 16,640 +/- 130 C14 age, calibrated age range 19,556-19,961 (1 s.d.), median probability 19,786 calibrated YBP. Correlative to Quadra Sand (Port Moody Interstade) and MIS 2.

• bed-level stratigraphic resolution

Environment/lithology: pond; unlithified siltstone

• Still-water backwater pool
• Twig-rich silts and fine sands

Size classes: macrofossils, mesofossils

Preservation: original chitin

Collected by Robert Nelson, Russell Coope

Collection methods: bulk, sieve,

• The sediments were disaggregated by wet sieving and the fraction remaining on the 300 micron mesh sieve was soaked in lamp oil (kerosene, paraffin oil) and the chitin floated from the mostly organic fraction using water.

•Repository: personal collection of Robert Nelson.
