Muir-Wood & Cooper 1960
Kozlowskia splendens is a species of brachiopod described in the Brachiopods of Ohio book. The species is reported from the Brush Creek limestone. I originally wrote this post about specimen CG-0008, but it turned out to be Eomarginifera longispinus. The difference? The so-called ears of the shell. This is the widest point of the shell. In Kozlowskia, the ears are near the hinge. In Eomarginifera, they are near the middle.
Taxonomy of Kozlowskia splendens
Several species I deal with have a reference in the Paleobiology Database, but this species has no such reference. Kozlowskia is listed, with ten species under it
Kozlowskia splendens specimens from the Brush Creek of Ohio
Three specimens are photographed in the Pennsylvanian Brachiopods of Ohio publication. These are specimens OSU-25978, OSU-25979 and OSU-25980. There are clear similarities between these specimens and Eomarginifera, however note how the hinge it easily the widest part of the shell. This is a clear way to identify Kozlowskia.
