Re: Now this muddles things up stratigraphically...
The gist of this: the main fossil bearing units of the uppermost Chinle
(esp. the Coelophysis quarry), once thought to be Carnian (early Late
Triassic), and more recently as Norian (mid-late Late Triassic), may be
Rhaetian (latest Late Triassic) or even earliest Hettangian.
An end-Triassic age would fit well with the very similar fauna at Lipie
