Strophomenata - Strophomenida - Rafinesquinidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|L R. M. Cocks and R.-b. Zhan 1998||Like Rafinesquina but with ventral valve bounding ridges surrounding a suboval muscle field; cardinal process lobes weaker and erect rather than anteriorly directed and with socket ridges better developed.|
