B. S. Kues et al. 2002 | The valve surface lacks ornamentation except for irregular, comarginal wrinkles. Although incomplete, the unusual size as well as the shape and proportions of this valve leave little doubt that it is S. trapezoides, a species thoroughly discussed by Pojeta (1988) and described from Virgilian strata of central New Mexico by Kues (1992). |
