Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Křiž 2010 | In adult shells the length/width relation (L/W) ranges from 1.1 to 0.5 (average 0.8), height/width relation (H/W) ranges from 0.8–1.3 (average 1.1). Umbonal angle 44–89° (average 66°). The shells are longer than in Kenzieana bellula from the late Wenlock (early Homerian), have more numerous radial ribs posteriorly of carina (> 71 in number) and thinner shell wall. Two blunt, possibly spoon like and quite long, slightly dorsally curved teeth are developed on the left valve. Between two corresponding sockets on the right valve is developed one long, spoon like tooth curved dorsally and leaning against the interspace between the teeth of the left valve. |
