Pododesmus patelliformis, the ribbed saddle-oyster, is a species of bivalve mollusc in the family Anomiidae. It is found in the north east Atlantic Ocean.
This oyster has a thin asymmetric shell up to four centimetres in length which is white, sometimes with brown markings. The outline is roughly circular and the beaks are central but set back from the margin. The upper valve is sculptured with up to sixty weak radial riblets, and the inside is glossy white or tinged yellowish-green with two distinct, furrowed muscle scars on the upper valve. The lower valve is flat, thin, transparent and hyaline and has one muscle scar.[2][3][4]
