Reference
Title: Late Triassic (Norian) mollusks from the Taylor Mountains Quadrangle, southwestern Alaska ,  2002
Bivalve and gastropod affinities suggest an early Norian age, with taxonomic similarities to several southern Alaskan tectonostratigraphic terranes (for example, Alexander and Chulitna), as well as to the South American Cordillera of Peru. The mollusks are associated with numerous brachiopods that also support a Norian age and similar biogeographic affinites.
