Abstract

Conodonts from two localities on the western shore of Alberto Island, southeastern Alaska, include Polygnathus alexanderensis n. sp., P. angustipennatus, P. borealis n. sp., P. praetrigonicus n. sp., P. robusticostatus, P. pseudofoliatus, P. linguiformis linguiformis gamma form of Bultynck, P. parawebbi beta form of Chatterton, P. angusticostatus, P. costatus costatus, Polygnathus sp. B of Savage, 1977, Tortodus kockelianus australis, and T. kockelianus kockelianus. The faunas are considered to be of middle to late Eifelian (kockelianus Zone) age. On Prince of Wales Island, just north of Staney Creek, exposures of Wadleigh Limestone include the conodonts Polygnathus trigonicus, P. kennettensis, P. alexanderensis, P. angustipennatus, P. parawebbi beta form, P. eiflius, P. linguiformis linguiformis gamma form, P. borealis, P. angusticostatus, P. robusticostatus, P. costatus costatus, P. pseudofoliatus, Tortodus kockelianus australis, and T. kockelianus kockelianus, also suggesting a middle to late Eifelian (kockelianus Zone) age. Conodonts from the west end of the easternmost of the Alberto Islands include Polygnathus linguiformis linguiformis gamma form, P. parawebbi beta form, P. xylus ensensis, and Ozarkodina brevis, indicating a late Eifelian to early Givetian (ensensis to varcus Zones) age. The presence of Polygnathus kennettensis, P. parawebbi beta form, and P. borealis suggests a biogeographic affinity with other parts of western North America during Eifelian time.
