Flabellipecten beali
Taxonomy
Pecten (Pecten) beali was named by Hertlein (1925). Its type specimen is LSJU (no number), a shell, and it is a 3D body fossil.
It was synonymized subjectively with Pecten (Janira) stearnsii by Grant and IV and Gale (1931); it was recombined as Flabellipecten beali by Moore (1984), Powell (2008).

---|---|---|
L. G. Hertlein 1925 | Shell inequivalve, plano-convex, equilateral, the ventral margin evenly rounded. Right valve convex, ornamented by about 23 or 24 prominent, square, flat-topped, strongly medially sulcate radial ribs, with in some cases, fainter radial grooves superimposed; interspaces flat-bottomed and slightly narrower than the ribs, the whole surface sculptured by fine, regular, concentric lines; posterior ear sculptured by about four radial riblets, and by fine incremental lines. Left valve flat or slightly concave, ornamented by about 21 radiating ribs separated by flat-bottomed interspaces, each of which bears a single small intercalated riblet, the ribs and interspaces crossed by fine concentric lines; a somewhat depressed area is found just below the beak; margins of shell somewhat concave, bearing four or five radiating ribs and fine concentric imbricating lines; ears somewhat concave, ornamented by three or four radiating riblets and by fine concentric lines of growth. Altitude 55 mm. ; longitude 56 mm. ; diameter of right valve approximately 10 mm. ; apical angle of right valve approximately 114°. |
