Where: Nova Scotia, Canada (43.8° N, 60.6° W: paleocoordinates 43.5° N, 55.3° W)
When: Miocene to Miocene (23.0 - 23.0 Ma)
Environment/lithology: marine; silty lithology not reported
•the sands tended to be replaced by silts.
Size class: microfossils
Collection methods: Each sample was oven dried, then weighed. Weights ranged from 100 to over 600g, but most were between 200 and 400 g. No presoaking in any detergent or other chemical was required, as all the samples were unconsolidated. The samples were
•washed through a stack of sieves, the top sieve with a 1.700 mm opening, the middle sieve with a 0.250 mm opening and a bottom sieve with a 0.063 mm opening. The residue was later dried and weighed, and a 5 to 60 g subsample of the 0.250 to 1.700 mm size fraction was set aside for palynological analysis.
