Where: Nova Scotia, Canada (46.0° N, 61.6° W: paleocoordinates 8.0° S, 5.1° W)
• coordinate based on nearby landmark
When: Port Hood Formation (Cumberland Group), Westphalian A (318.7 - 316.9 Ma)
• "near the middle of the Port Hood Formation, part of the coarse fluvial facies of Belt [1964, Am. J. Sci. 262] and the Riversdalean Stage of earlier authors. On the basis of nonmarine crustaceans [Copeland, 1957, Geol. Surv. Can. Mem. 286], plants [Bell, 1944, Geol. Surv. Can. Mem. 238], and microspores [Belt, 1964] the age of the Port Hood Formation is Early Pennsylvanian and equivalent to the Westphalian A of Europe." (Baird & Carroll, 1967)
• bed-level stratigraphic resolution
Environment/lithology: wet floodplain; lenticular, brown, yellow sandstone and coal
Size class: macrofossils
Preservation: adpression, replaced with carbon
