Chulitnacula, a new paleobiogeographically distinctive gastropod genus from Upper Triassic strata of accreted terranes of southern Alaska
Original language description
A new protorculid gastropod genus, Chulitnacula, is established from the Chulitna terrane of south-central Alaska. The occurrence of Chulitnacula alaskana (Smith, 1927) in the Chulitna, Farewell (Nixon Fork subterrane) and Alexander terranes suggests that they were in close reproductive communication in the Late Triassic. The absence of this taxon in either the Wrangellia terrane of southern Alaska and British Columbia, as well as in the related Wallowa terrane of northeastern Oregon and adjacent western Idaho is worthy of note. This absence plus many other major differences in their respective Late Triassic gastropod faunas indicate that the Chulitna-Farewell-Alexander terrane association was far removed from the Wrangellia-Wallowa terrane couplet. While both faunal associations are characteristically tropical in aspect, their biogeographically differing faunas indicate that they were probably very distantly separated from one another in the Panthalassa Ocean at this time.
