...P. H. von Bitter; H. A. Plint-Geberl Abstract Four stratigraphically successive conodont assemblage zones have been recognized in the Lower Carboniferous Codroy Group of southwestern Newfoundland. The Diplognathodus Zone is confined to the basal Ship Cove Limestone, and to a highly fossiliferous...

Strictly speaking, Diplognathodus lacks a platform hut appears to be closely related to taxa that bear true platforms and aIso shows an evolutionary pattern much like that of platform-bearing genera. Three other genera are numerically important in these collections...

... of Diplognathodus. These Pa elements, which occur sparsely in the black shale and more commonly in the limestones, are included in diversity counts of Heckel and Baesemann (1975) as Ozarkodina minuta + spp. With these taxonomic considerations, the higher-diversity trends of the black-shale member would...

... of the “ Hindeodus - Diplognathodus Problems” (von Bitter and Merrill, 1985 , p. 81). In any case, for discrimination of the element set forming a Hindeodus apparatus, it is necessary to examine closely the stratigraphic co-occurrence and similarities of morphological characters between ramiform and Pa elements...
