Blowhole, North Blackmans Bay (B1) (Permian of Australia)

Where: Tasmania, Australia (43.0° S, 147.3° E: paleocoordinates 78.2° S, 142.7° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ferntree Formation, Wuchiapingian (259.9 - 254.2 Ma)

• Middle part of formation, 37-45 m below top of formation.

•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.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; lithified sandstone
