Abstract

The trilobite and brachiopod fauna of the Gap Creek Formation is revised. Recorded are the trilobites: Geragnostus aff. splendens, Opipeuter angularis, O. ?inconnivus, Carolinites ?genacinaca, Caningella hardmani, Encrinurella ?reedi, and several indeterminate forms. Brachiopods include ?Pseudomimella sp., ?Oligorthis sp., Tritoechia sp., Spanodonta hoskingiae, and Tinopena shergoldi gen. et sp. nov. Also recorded are the gastropods Teiichispira sp. and Helicotoma sp., and calcareous plates of uncertain affinities. Correlations based largely on the telephinid trilobites indicate this fauna is of late Bendigonian (Be3-Be4) age.
