Pinacodus profundus Branson et Mehl, 1934 from the Bushberg Sandstone of Missouri.

Opis

P1 elements with lanceolate, flat or inverted basal cavity separated by an escarpment from the rest of the platform base; ramiform elements with relatively short processes.
Emended diagnosis.- Aparatuses with sp elements characterized by lanceolate shape of the basal cavity with an almost flat surface and simple platform with transverse ribs and robust oz elements with smooth surface and blunt, obliterated denticles. Elements of the symmetry transition series with relatively short processes.
Remarks. - In Polish sections there is a continuity in distribution and apparatus morphology of the lineage of Pinacogrnthus. There seems thus to be little reason to separate these species in different genera and certainly there is no relationships between the late species of the lineage, whatever is its proper specific name, and species of Pseudopolygnathus. As they all seem to share closely similar and characteristic morphology of the oz elements, which is distinct from that in Siphonodella, they are here defined on this basis. With Siphonodella they share shape of the basal cavity and also some similarity in the apparatus structure
