The shell is characterized in having two dissimilar valves
which appeared to be oblong, ovate, elongate, bilaterally
symmetrical, endowed with parallel lateral margins, sharp
beaks and straight edges (Table 2 and Figs.2 to 5). Outer
surface of the valves were mostly found to be smooth but
indicating growth lines. The inner surfaces of the valves were
designed with different ornamental features. The ventral
valve possesses two hinge teeth fitting into opposing sockets
into the dorsal valve. Some bristles have been found at the
anterior margin of both valves, marked with lines on upper
side. Lower sides of the valves are endowed with signs of
muscle scars and mantle canals.
