New species of Patellogastropoda (Mollusca) from the Cretaceous of Hokkaido, Japan and Sakhalin, Russia
Rare patellogastropod limpets are described from the Cenomanian to Campanian (Cretaceous) age sediments in Hokkaido, northern Japan and Sakhalin, eastern Russia. Shell structure analysis has revealed the presence of five shell structure groups within six species, permitting the allocation of three o...
