Description
Summary:Fig. 5. Pholadid bivalve Pholadidea gradzinskii sp. nov. (ZPAL Mo. XVIII/3, holotype) from the Oligocene of King George Island. A. Left-lateral view of the complete specimen (A1), arrow marks deformation of the callum; anterior of the left valve (A2), showing callum covered with growth lines. B. Rightlateral view of the complete specimen (B1), arrow marks deformation of the callum; anterior of the right valve (B2), showing umbonal reflection raised anteriorly and appressed on the umbo. C. Dorsal view of the complete specimen showing metaplax formed by partially calcified periostracal mantle connecting the dorsal margin of the valves. D. Ventral view of the complete specimen showing a hypoplax formed by partially calcified periostracal mantle extending beyond the ventral margin of the shells and connected with the callum; arrows mark deformation of the callum and hypoplax. E. Inclined dorsal view of the anterior showing umbonal reflection covered with the dorsal extension of the callum. F.
