Arkhangelskiella striata Stradner, 1963
Placolith with cretarhabdid shields and a central area characterised by a fibrous axial cross that supports a solid distal process. Each quadrant bears four or more lateral bars. The spaces between these lateral bars contain two or more pores, which are aligned perpendicular to the lateral bars.
In Cretarhabdus, the pores are arranged in concentric rings.
