註釋Diverse and abundant Middle and Late Triassic elasmobranch ichthyoliths (microscopic shark teeth and scales) coexisting with conodonts, ammonoids, and bivalves recovered from carbonates in the Peace River area of British Columbia provide an excellent biostratigraphic framework for Triassic strata. This report provides systematic descriptions and illustrations of Triassic elasmobranch ichthyoliths including seven species of teeth and 19 new form genera and 53 new form species of scales. A provisional ichthyolith zonation for the Middle and Upper Triassic is proposed for the Peace River area, and new approaches to ichthyolith identification are discussed. Results from this study demonstrate the use of ichthyoliths in basin analyses to data and correlate strata.
