Campanian (Late Cretaceous) nautiloids from Sakhalin, Far east Russia
Three nautiloid taxa, Cymatoceras pseudoatlas (Yabe and Shimizu, 1924b), C. cf. bifidum Shimansky, 1975, and C. cf. honmai Matsumoto and Miyauchi, 1983, are recorded from the Campanian of Sakhalin, Far East Russia. These are the first biostratigraphically well dated nautiloids from Sakhalin, which s...
