坂本组含有所谓的Torinosu石灰岩，通常被认为是上侏罗纪。它的黑色页岩和石灰岩含有许多动物化石。表1总结了坂本的地层结果，图2和图3显示了化石地点。Ia-c和表2。表1中的层位5尤其是化石层，产出菊石。腹足类和棘足类。有些化石出现在较低或较高的层位。Aulacosnicktes是尼泊尔、印度、南阿比西尼亚高原、马达加斯加、墨西哥和阿根廷等地的一种提顿期的向导化石。1956年，在坂本（Loc. 4）。(See表2和图图lb、c）。这里描述的pelecypods属于-
The Sakamoto formation containing the so-called Torinosu limestone is generally thought Upper Jurassic. Its black shale and limestone contain many animal fossils. Stratigraphic results at Sakamoto are summarized in Table 1 and fossil localities shown in Figs. la-c and Table 2. The horizon 5 in Table 1 is especially fossil iferous, yielding ammonites. pelecypods, gastropods and echinoids. Some fossils occur in the lower or upper horizons. Aulacosphinctes which is a guide fossil of Tithonian in Nepal, India, South Abyssinian plateau, Madagascar, Mexico and Argentina (ARKELL. 1956) was collected at Sakamoto (Loc. 4). (See Table 2 and Figs. lb, c). Here are described pelecypods belong-
