Hustedia mormoni

Rhynchonellata - Athyridida - Neoretziidae

Taxonomy
Terebratula mormonii was named by Marcou (1858) [Terebratula Mormonii]. It is a 3D body fossil. Its type locality is Vicinity of Salt Lake City, which is in a Bashkirian carbonate limestone in the Round Valley Formation of Utah.

It was recombined as Hustedia mormonii by King (1931); it was recombined as Hustedia mormoni by Girty (1915), Morningstar (1922), Dunbar and Condra (1932), Gehrig (1958), Hoare (1961), Mudge et al. (1962).

Diagnosis
ReferenceDiagnosis
J. L. Gehrig 1958Shell small, gibbous, ovate, longer than wide. Greatest width anterior to middle; greatest thickness slightly posterior. Two typical specimens measure: Length 9 mm, 8 mm; width 7 mm, 6 mm; thickness 6 mm, 5 mm.

Dorsal valve thicker than the ventral. Convexity greatest transversely; longitudinally it is moderate from beak to umbo and gentler thereafter. Beak small and inconspicuous. Marked by 13 coarse, simple radial plications.

Ventral valve moderately convex longitudinally; flattened medially, with the lateral slopes dropping off steeply. Beak narrow, elevated, rather prominent, overarching a small triangular symphytium, and terminated by a small round foramen. An extremely faint, broad sinus usually can be distinguished on the anterior half. Line of commissure jagged. There are 14 plications (similar to those on the dorsal valve) on 2 complete specimens, but 1 broken specimen bears 16.
