LH0 (Ordovician of Canada)

Where: Newfoundland, Canada (50.0° N, 57.8° W: paleocoordinates 28.1° S, 41.9° W)

• outcrop-level geographic resolution

When: Periodon macrodentatus conodont zone, Factory Cove Member (Shallow Bay Formation), Darriwilian (467.3 - 458.4 Ma)

• Bed 15

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, peloidal, gray grainstone

• The gastropods occur in light gray grainstone composed of well-sorted, sand-sized fragments of calcareous algae, micritized echinoderms, and peloids suggesting deposition in a shallow, high-energy environment.

Size class: macrofossils

Preservation: replaced with silica
