2. Shigeta Yasunari, Maeda Haruyoshi, The Cretaceous System in the Makarov area, southern Sakhalin, Russian Far East, National Science Museum, Tokyo, National Science Museum Monographs, No.31, 1—136, 2005.12, The Cretaceous Yezo Group in the Makarov area was closely investigated stratigraphically and paleontologically. The group exposed there ranges from Santonian to Maastrichtian in age, and attains 2,500 m thick in total. It is divided into the Bykov and Krasnoyarka formations in upward sequence. The former consists mostly of offshore mudstones, and is lithologically subdivided into four lithostratigraphic units: B1-B4. The latter is composed mainly of near shore sandstones and deltaic deposits, and is subdivided into five units: K1-K4b.
 Except for the uppermost part of the Krasnoyarka Formation, the Cretaceous strata are very fossiliferous. Among the fossil fauna, pachydiscid, tetragonitid, and gaudryceratid ammonoids are especially abundant. Sphenoceramus shmidti of the Lower Campanian age also occurs numerously, and forms the characteristic S. schmidti Zone, which is widely traceable throughout the area. It is noticeable that the nearly complete faunal-succession during Campanian and Maastrichtian age is continuously observed there even though internationally stage-diagnostic taxa are few.
 The sedimentary features of mudstone and the faunal composition of the Yezo Group are similar thoughout South Sakhalin and Hokkaido. Although a few fossil zones obliquely extend over the stratigraphic units, almost identical litho- and biofacies extend over 900 km from south to north. Such depositional- and faunal uniformity reflecting global marine environments in the North Pacific is a remarkable characteristic of the Yezo Group..
