Bivalvia - Pectinida - Prospondylidae
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.
|M. Hautmann 2001||Relatively small forms of variable outline. Ligament area narrower, but resilifer broader than in other members of the Prospondylidae, thus more oyster-like in appearance|
