Diagnosis
ReferenceDiagnosis
B. S. Kues et al. 2002The beaks are high, narrow, strongly curved, and opisthogyrate, and although the specimens are crushed, remnants of a shallow escutcheon are preserved along the hingeline. The ornamentation is the distinctive pattern of step-ribs—narrow comarginal bands that are high dorsally but slope ventrally (Yancey, 1978)—that characterize the species. On weathered specimens the high margins of these bands tend to become isolated, giving the appearance of sharp, comarginal lirae.
