| 520 | 3 |a"Data are given on the morphology and distribution of all known Canadian Triassic Ammonoidea, except the Arcestaceae. Material is described from about 850 localities in the Arctic Islands, Yukon, British Columbia and Alberta. Localities in the Arctic Islands are in the Sverdrup Basin. Except for one collection from a well in northwest Alberta, all specimens from Western Canada are from exposures in the Cordillera. A biochronology is proposed covering the whole of the Triassic, from the earliest (Early Griesbachian) to latest (Late Norian). Fifty-six divisions (zones, subzones, horizons) are recognized, grouped within stages and substages as follows: Lower Griesbachian (2), Upper Griesbachian (2), Dienerian (4), Smithiun (3), Spathian (2), Lower Anisian (3), Middle Anisian (3), Upper Anisian (2), Ladinian (1 O), Lower Carnian (3), Upper Carnian (4), Lower Norian (7), Middle Norian (7), Upper Norian (4). The ammonoids are classified as 522 species (243 new) in 256 genera (46 new)"--Abstract, page 1. |
