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
