AbstractNew conodont collections from both outcrop sections and subsurface drill core improve the correlation of Anisian (Middle Triassic) strata in British Columbia. New conodont species and morphotypes identified in these collections are used to define new informal conodont faunal assemblages. This preliminary biostratigraphical scheme allows correlation of the Anisian between surface and subsurface sections in British Columbia for the first time, as illustrated by four of the sections studied. Improved correlation has led to a revision of the interpretation of the depositional environment of Anisian rocks in British Columbia, from that of a continental margin to that of a restricted basin. The recognition of some of the new conodont taxa in collections from Nevada and the Canadian Arctic indicates that some of the faunal assemblages may prove useful for regional correlation and placement of the sub-stage boundaries of the Anisian.
Summary(Plain Language Summary, not published)
New conodont collections from Anisian (Middle Triassic) strata in British Columbia include new taxa that are used to define informal conodont zones. This allows correlation between surface and subsurface sections and leads to a revised interpretation of the depositional environment of Anisian rocks in British Columbia from that of a continental margin to that of a restricted basin. The recognition of some of the new conodont taxa in collections from Nevada and the Canadian Arctic indicates that some of the faunal assemblages may prove useful for regional correlation.
