Hamilton Peninsula (Permian of Canada)

Also known as Ellesmere Island

Where: Nunavut, Canada (80.4° N, 81.2° W: paleocoordinates 36.8° N, 5.7° E)

• coordinate stated in text

When: Sabine Bay Formation, Kungurian (279.5 - 272.5 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; black shale

• The rare acanthomorph acritarchs point to some marine influence at this locality, which is located within the Sverdrup Basin, an asymmetrical, northeasterly-trending basin in the Canadian Arctic Archipelago. Rifting occurred during the Early Carboniferous time, followed by extensional pulses. Fault controlled subsistence took place p until the Kungurian, when a significant phase of compressional tectonics resulted in the inversion of older rift-related structures. This event is known as the "Melvillian Disturbance."
• Samples were collected from black coaly shales. The Sabine Bay formation also contains conglomerates, sandstones, and minor coaly shales.
