Final Epithet
Retecapsa tetralateralis Varol, in prep.
Basionym
Retecapsa tetralateralis Varol, in prep.
Etymology
From Greek tetra (four) and Latin lateralis (lateral), referring to the four lateral bars per quadrant.
Description
The placolith comprises a cretarhabdid pelaga sloping towards the central area, formed of inclined segments that generally display weak clockwise imbrication, and a distally arched central area characterised by an axial cross supporting a solid distal process.
The inter-cross area is occupied by lateral bars that delimit pores arranged in a single complete concentric cycle. Each quadrant typically contains five pores formed by four lateral bars, a feature characteristic of Retecapsa tetralateralis.
Optical Properties
Optical properties consistent with those of Retecapsa.
