Redmond No. 1, Knob Lake District (Dorf collection) (Cretaceous of Canada)

Where: Newfoundland and Labrador, Canada (54.7° N, 66.8° W: paleocoordinates 46.4° N, 27.3° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Redmond Formation, Cenomanian (100.5 - 93.9 Ma)

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; lithified, ferruginous claystone

• Harrison et al. (1972) noted normal faults and grabens associated with the Redmond Formation, and Gastil et al. (1960) hypothesized that the Redmond Formation iron-rich talus was deposited in a newly formed Cretaceous structural basin. Widespread igneous activity and regional faulting in eastern Canada and the northeastern United States have been associated with extension and opening of the Atlantic Ocean (Norris, 1993). However, Faure et al. (1996) attributed the regional structural fabric of eastern Canada and New England to the extensional regime associated with the initiation of rifting between Labrador and Greenland ca. 140 Ma.
• "hard, ferruginous argillite"

Size class: mesofossils

Preservation: adpression, soft parts

Collected by E. Dorf in 1958; reposited in the GSC

• Repository: also Princeton University
