Mattiolia furva


Classification: Mesozoic -> Podorhabdales -> Cretarhabdaceae -> Mattiolia -> Mattiolia furva
Sister taxa: M. furva, M. sp.,

Distinguishing features: Medium-sized (~5.5 µm), broadly elliptical placoliths with a distinctly dark image in XPL and a central area equivalent in width to the shield. The central area is filled by a broad axial cross that may form a complete plate. The central area plate, like the shields, has a dark appearance under XPL but is crossed by at least four extinction lines, axially and diagonally orientated.
