Description
Summary:Early Famennia microvertebrates from the Cape Fortune Member, Parry Islands Formation, of the Beverley Inlet area of Melville Island, Arctic Canada, comprise the teeth and possible scales of a new phoebodontid shark, Phoebodus rayi sp.n., of a protacrodont shark, Protacrodus aequalis IVANOV, and rare teeth of other sharks. The new phoebodont from the early Famennian crepida Zone is closely related to the Lazarus taxon, Ph. typicus GINTER & IVANOV. Ph. typicus emerges in the early Famennian Late triangularis Zone following the phoebodont shark hiatus subsequent to the Kellwasser Event which apparently caused extinction of most earlier phoebodonts.
