Boulder 14 (Levis) (Cambrian of Canada)
Where: Quebec, Canada (46.8° N, 71.2° W)
• Paleocoordinates: 10.2° N, 95.3° W (Wright 2013)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Hungaia trilobite zone, Trempealeauan (490.2 - 486.9 Ma)
Environment/lithology: marine; lithified, gray, sandy limestone
• Fauna is sampled from conglomerate boulders which "usually consist of pure, fine-grained limestone ranging in color from light to dark gray, the latter often assuming a purplish hue. Quartz sand may occur in these limestones, and in a few instances its percentage is so high that the rock might rather be designated as a calcareous sandstone."
Size class: macrofossils
