“…The coal‐bearing siltstone successions of the Pennsylvanian Joggins Formation of Nova Scotia may also include sandy siltstones in the green‐grey siltstones of the poorly‐drained floodplain facies assemblage (Davies & Gibling, ). The Lower Pennsylvanian Buffalo Wallow Formation of Hancock County, Kentucky, contains a comparable vertebrate fauna of tetrapods, dipnoans, rhizodonts, actinopterygians, acanthodians and chondrichthyans within abandoned channel and oxbow facies (Garcia et al ., ; Greb et al ., ). Although sandy siltstones are not identified, tetrapod remains are also found within rooted siltstone palaeosol horizons, which could be analogous to the original environment of the Ballagan Formation tetrapods.…”
