GSC 402, Baillie-Hamilton Is. (Silurian of Canada)

Also known as Trilobite-Ostracode Fauna, Cape Phillips Fm.

Where: Northwest Territories, Canada (75.8° N, 94.5° W: paleocoordinates 3.5° N, 32.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cape Phillips Formation, Sheinwoodian (433.4 - 430.5 Ma)

• Parts of section yielding trilobites are from about 97.5 ft. to 245 ft. above base, spanning early Wenlockian Cyrtograptus canadenses through penultimate Wenlockian Monograptus testis zones.

• bed-level stratigraphic resolution

Environment/lithology: slope; shelly/skeletal limestone and calcareous shale

• SEP environmental call based on given info and regional context
• "alternating fine grained, argillaceous limestones and lesser amounts of interbedded calcareous shale and biogenic limestone" Column shows the last two named lithologies to be most relevant to these collections.
