Its age is constrained by palaeo-magnetic correlation to the Newark basin astrochronology and marine sequences (Kent and Olsen 1999; Muttoni et al.
Below the ETE, the White Water and Red Head members of the Blomidon Formation are correlated to the Newark basin astrochronology via palaeomagnetic polarity stratigraphy (Kent and Olsen 2000), which provides a temporal resolution of less than one million years and a substage-level of correlation to marine sections for the Norian and Rhaetian; but this is not true of the important St Mary's Bay assemblage of tetrapod tracks, which has not yet been directly tied to the polarity sequence.
Based on the polarity stratigraphy in the GAV-77-3 core and correlation to the Newark basin astrochronology (Kent and Olsen 2000), the age the White Water Member is 213 to 201.
