A conodont zonation is recommended for all conodont domains to be used in recognition of conodont biofacies and consideration of provinces during the Triassic.

Four principal conodont biofacies are recognized and precisely defined, viz., Neogonaolella- Paragondolella, Parachirognathus- Furnishius, Carinella-Pseudofurnishius, and Gladigondolella. Both vertical and horizontal distribution of component bioelement of conodont biofacies is described, and their paleoecological or lithological characteristics discussed. The stratigraphic and geographic characteristics, presence of conodont biofacies, relative diflerences or similarities, etc. of the Triassic conodont provinces (Tethyan-Pacific, Germanic and Balkanide) are discussed in detail.

Abstract


A conodont zonation is recommended for all conodont domains to be used in recognition of conodont biofacies and consideration of provinces during the Triassic.

Four principal conodont biofacies are recognized and precisely defined, viz., Neogonaolella- Paragondolella, Parachirognathus- Furnishius, Carinella-Pseudofurnishius, and Gladigondolella. Both vertical and horizontal distribution of component bioelement of conodont biofacies is described, and their paleoecological or lithological characteristics discussed. The stratigraphic and geographic characteristics, presence of conodont biofacies, relative diflerences or similarities, etc. of the Triassic conodont provinces (Tethyan-Pacific, Germanic and Balkanide) are discussed in detail.
