  4. Research paper (bulletin of university, research institution) Joint Late Cretaceous Reptile fossils from Nakaminato Group, Hitachinaka-City, Ibaraki Prefecture Taichi Kato, Yoshiki Koda, Hisao Ando, Teppei Sonoda and Genya Masukawa Bulletin of Ibaraki Nature Museum Ibaraki Nature Museum 20, 7-14 2017/12 1343-8921 URL Three reptile fossils occurred from the Isoai Formation of the Nakaminato Group (Campanian-Maastrichtian) exposed along the Pacific coast in Hitachinaka City, Ibaraki Prefecture, Japan. One is a scapular of Ornithocheiroidea (cf. Nyctosauridae) pterosaur. To date only two Nyctosauridae specimens have been reported from these stages in the world, this specimen may be an important record reconstructing for the diversity and distribution of late Cretaceous pterosaurs. The second is a caudal vertebra possibly of a juvenile or small-sized mosasaur. This indicates the similarity of apex predators of vertebrate fauna between the Nakaminato and Izumi groups, as well as the similarity of their sedimentary facies and invertebrate fossil fauna. The third is a costal of soft-shelled turtle (Trionychidae), whose shell length is estimated to be about 80 cm. This specimen may have deposited as a debris transported from non-marine habitat.

Research paper (scientific journal) Joint Reconstruction of the Cretaceous Paleo-Japan continental arc-trench system reconsidered from Cretaceous geologic records in the Japanese Islands Hisao Ando and Masaki Takahashi Fossils Palaeontological Society of Japan 102, 43-62 2017/09 0022-9202 URL As a premise for reconstructing the Paleo-Japan Cretaceous continental arc-trench system, its constituent geologic units such as Cretaceous plutonic, volcanic and sedimentary rocks are briefly reviewed, referring to recently published many papers, books and maps. Mainly non-marine Lower Cretaceous strata are sporadically distributed in separated intra- and back-arc small basins around the volcanic arc in Southewest Japan. On the other hand, mainly marine and subordinately fluvial Cretaceous strata are distributed sporadically but continuously along the Pacific coastal area and the offshore Pacific subsurface in NE Japan, and the southern end of the Inner Zone and the Chichibu Belt of the Outer Zone in SW Japan. Their stratigraphy and sedimentary environments are broadly correlated as forearc basin fills throughout two arcs of SW and NE Japan. The present land area of Northeast Japan is equivalent to the Inner Zone of Southwest Japan. On the other hand, the Outer Zone of Southwest Japan will be traced into the subsurface area of the offshore Pacific in Northeast Japan.

Oral presentation(general) モンゴルの白亜系湖成層中に見られる堆積リズムの起源:海洋無酸素事変時の陸域環境変動解明に向けて 日本地球化学会年会要旨集 2011 URL 本研究はモンゴルのアプチアン期湖成層(シネフダグ層)を対象に,OAE1a時の陸域環境変動の解明を試みている.シネフダグ湖成層は,頁岩とドロマイトのリズミカルな互層(数10cm,数m,10~20 mサイクル)からなる.本研究では,その堆積メカニズムを解明するため,堆積相解析,鉱物組成分析,有機地球化学分析を行った.C/N比およびロックエバル分析の結果,シネフダグ湖成層の有機物は主に湖内の藻類に由来することが示唆された.またドロマイト層準では藻類やバクテリアが卓越するのに対し,頁岩層準では藻類に加えて湖岸からの高等植物起源有機物の流入も寄与していたことが示唆された.これらの結果と堆積相解析から,シネフダグ湖成層に見られる頁岩とドロマイトのリズミカルな互層(数千年,数万年,数10万年サイクルに相当)は,地球軌道要素の変動に起因した湖水位の変動,すなわち湿潤-乾燥といった気候変動に対応している可能性が示唆された.
