Abstract

Massive Upper Triassic (Norian) reef limestone at Eaglenest Mountain, Takla Group, British Columbia, contains a wide variety of shallow-water fossils in two different carbonate units. A sponge-coral facies contains the sponges Fanthalamia astoma (Seilacher, 1962), Fanthalamia multicanalis new species, Cinnabaria expansa (Seilacher, 1962), and Cinnabaria? sp. Cinnabaria expansa is a widely distributed North American terrane species which, along with F. astoma, was previously known from the Luning Formation of Nevada. Also included is the "disjectoporoid," Pamiropora sonorensis Stanley, 1994, and a massive spongiomorph, Spongiomorpha tenuis Smith, 1927, previously endemic to the Eastern Klamath terrane of California. Colonial corals include: Retiophyllia quesneliana new species, Chondrocoenia waltheri (Frech, 1890), Crassistella cf. juvavica (Frech, 1890), Distichomeandra cf. austriaca (Frech, 1890), and Alpinophyllia flexuosa Roniewicz, 1989. A limestone conglomerate overlying these beds is dominated almost exclusively by the planktonic hydrozoan, Heterastridium conglobatum Reuss, 1865. A problematic taxon Lovcenipora cf. chaetetiformis Vinassa de Regny, 1915, is reported for the first time outside Timor and the Tethys. The faunas provide a first glimpse into the reef biota of the Quesnel terrane. They contain taxa previously known from the distant Tethys but also include endemics from other inboard terranes.
