Ellesmere Island (Lower) (Eocene of Canada)

Also known as Bay Fiord; Locality 76-85 (locality 85 and CMN loc. P7502); D7 Locality; localities 44, 49 (= 76-49?), 76-60, 76H7-10-1, 76H7-10-3, Mck7/15/87-1

Where: Northwest Territories, Canada (78.5° N, 82.0° W: paleocoordinates 75.8° N, 30.2° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Margaret Formation (Eureka Sound Group), Wasatchian (55.8 - 50.3 Ma)

• said by Hickey et al. 1983 to be Clarkforkian and within Chron 25N, but clearly Wasatchian, and paleomag correlation seriously questioned by Kent et al. 1984

•Eureka Sound Group was originally treated as a formation, but broken into multiple formations by Miall (1986); the Margaret Formation is the same as Member IV of West et al. (1981)

• member-level stratigraphic resolution

Environment/lithology: deltaic; lithology not reported

• "lush proximal delta front to delta plain environment, with abundant channels and coal swamps" (Rose et al. 2004)

Size classes: macrofossils, mesofossils

Reposited in the CM

Collection methods: bulk, surface (float), sieve,

• "Approximately 500 pounds of matrix from this locality [76-85] was screen-washed"
