Fig. 13B.
Material.—One incomplete ventral valve.
Remarks.—The single specimen has a semicircular to subquadrate outline, medium convexity, flat orthocline ventral interarea preserving small traces of the pseudodeltidium along the edges of the triangular delthyrium. Externally there is rather coarse radial ornamentation with a density of 2 costae per mm at 3 mm distance from the ventral beak. Internally the teeth are transverse, plate−like, and subparallel to the hinge line. The ventral median septum is short. The specimens are here attributed to Plicochonetes mainly because of the rather coarse radial costae.
Stratigraphic and geographic range.—It was recovered from M2−8, about 3.5 m above base of the Muhua Formation.
