Stratigraphy
| Geological group: | Back Creek | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Presence of Echinalosia ovalis suggests an age within the E. ovalis zone, correlated with the middle part of APP5 palynomorph zone (Briggs, 1998). The APP5 zone was constrained as mid-Wuchiapingian through Changhsingian age by U-Pb dating in Laurie et al. (2016). However, overlying units in the Fort Cooper Coal Measures yield latest Wuchiapingian U-Pb ages (Phillips et al., 2018), constraining the upper Blenheim Fm to Wuchiapingian. | |||||
