Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. S. Kues et al. 2002 | The valves are elongate-oval in outline, strongly inflated, and possess low, strongly opisthogyrate beaks situated subterminally near the posterior margin. Below the beaks, the posterodorsal margin is distinctly concave, and the lunule and escutcheon are weak to obscure. On relatively undistorted specimens, the width/ length ratio exceeds the height/length ratio. Ornamentation is limited to irregular, often obscure growth lines. Comparison with a large sample of N. girtyi specimens from the Desmoinesian of north-central New Mexico (Kues, 1984) indicates that the Bar B specimens tend to be lower and more elongate, have less prominent beaks, and attain a larger size. |
