Rhynchonellata - Rhynchonellida - Leptocoeliidae
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.
|J. G. Johnson 1970||Leptocoeliid brachiopods with relatively numerous, evenly spaced, concentric growth lamellae and sparse, low, radial plications. Ventral diductors small, narrow, and anteriorly platformed; cardinalia includes a simple, knoblike cardinal process.|
