Age distribution and provenance of limestone fragments contained in the Kamade Breccia of the Upper Cretaceous Aioi Group, distributed in the western part of Hyogo prefecture, Japan were considered. Among 67 samples examined, 19 are Carboniferous (Serpukhovian to Gzhelian), 20 are Permian (Sakmarian to Capitanian), and two are Triassic (early Anisian). Two samples of conglomeratic limestone contain both Carboniferous and Permian foraminifers. The ages of the other 28 samples are indeterminable. Of these 28, four are assumed to be post-Triassic. Carboniferous and Permian limestone fragments and a subduction-related broken limestone pebble of unknown age are concluded to have been derived from the Akiyoshi Terrane, and early Anisian ones from the Maizuru Terrane. The source of the post-Triassic boulders and cobbles consisting of very fine-grained lime-mudstone cannot be determined because there is no plausible limestone in Japan from which they could have been derived. Systematically described fusulinoideans comprise seven species of ozawainellids, fusulinids, and schwagerinids. They are Eostaffella kanmerai, Eostaffella yowarensis, Pseudofusulinella itoi, Rauserites stuckenbergi, Schwageriniformis schwageriniformis, Triticites simplex and Paraschwagerina sp. This paper is the latest in a series of works whose aim is a complete description of the Hyogo foraminifera.
