The Ferntree Fm is the youngest marine Permian unit in Tasmanian, of late Lymingtonian age. Briggs (1998) correlated the late Lymingtonian with his mainland brachiopod zones, ranging from the Echinalosia wassi zone to the Echinalosia deari zone and with palynological zones APP4.3 and APP5. Radiometric calibration of these palynologyical zones by Laurie et al. (2016) suggests that APP4.3 is mid-Wuchiapingian and APP5 spans the late Wuchiapingian and Changhsingian. A Wuchiapingian age is assigned to the Ferntree Formation here. | |||||
