    Preliminary Survey on the Tetori Group in Southern Ishikawa, Japan 石川

    石川県立自然史資料館研究報告 第３号 Bulletin of the Ishikawa Museum of Natural History, 3: 49-62 (2013) Preliminary survey on the Tetori Group in southern Ishikawa, Japan Yoshihiro KATSURA 石川県南部に分布する手取層群に対する予備調査 桂嘉志浩 Abstract The Lower Cretaceous Itoshiro and overlying Akaiwa subgroups of the Tetori Group are distributed in the Shiramine Area of Hakusan City, Ishikawa Prefecture, Japan. The Kuwajima Formation, the upper division of the lower subgroup, is considered to have been deposited under lacustrine and associated alluvial environments. It has yielded a reasonable number of vertebrate remains that are small, allochthonous, and mostly disarticulated. The Akaiwa Formation, the lower division of the upper subgroup, is suggested to have been formed by fluvial systems with strong currents and rapid deposition. Except for plant fragments, fossils are uncommon. Vertebrates, including dinosaurs, occur in the Kitadani Formation, the upper division of the upper subgroup, in northeastern Fukui Prefecture, and this formation crops out in the Shiramine Area. Therefore, there is a chance that articulated large vertebrate fossils are preserved in the subgroups exposed in the area. However, the indurated nature of the rocks, precipitous topology, thick vegetation cover, and overall poor exposures represent significant challenges to making such a discovery. Further, based on the taphonomy of the observed vertebrates, finding well-preserved large vertebrates in the area will be difficult and require much time and financial support.

    ARTICLE https://doi.org/10.1038/s42003-020-01222-7 OPEN A neoceratopsian dinosaur from the early Cretaceous of Mongolia and the early evolution of ceratopsia ✉ Congyu Yu 1 , Albert Prieto-Marquez2, Tsogtbaatar Chinzorig 3,4, Zorigt Badamkhatan4,5 & Mark Norell1 1234567890():,; Ceratopsia is a diverse dinosaur clade from the Middle Jurassic to Late Cretaceous with early diversification in East Asia. However, the phylogeny of basal ceratopsians remains unclear. Here we report a new basal neoceratopsian dinosaur Beg tse based on a partial skull from Baruunbayan, Ömnögovi aimag, Mongolia. Beg is diagnosed by a unique combination of primitive and derived characters including a primitively deep premaxilla with four pre- maxillary teeth, a trapezoidal antorbital fossa with a poorly delineated anterior margin, very short dentary with an expanded and shallow groove on lateral surface, the derived presence of a robust jugal having a foramen on its anteromedial surface, and five equally spaced tubercles on the lateral ridge of the surangular. This is to our knowledge the earliest known occurrence of basal neoceratopsian in Mongolia, where this group was previously only known from Late Cretaceous strata. Phylogenetic analysis indicates that it is sister to all other neoceratopsian dinosaurs. 1 Division of Vertebrate Paleontology, American Museum of Natural History, New York 10024, USA. 2 Institut Català de Paleontologia Miquel Crusafont, ICTA-ICP, Edifici Z, c/de les Columnes s/n Campus de la Universitat Autònoma de Barcelona, 08193 Cerdanyola del Vallès Sabadell, Barcelona, Spain. 3 Department of Biological Sciences, North Carolina State University, Raleigh, NC 27695, USA. 4 Institute of Paleontology, Mongolian Academy of Sciences, ✉ Ulaanbaatar 15160, Mongolia.

The shark fauna of the Upper Cretaceous Hinoshima Formation (Santonian: 86.3–83.6 Ma) of the manuscriptHimenoura Group (Kamiamakusa, Kumamoto Prefecture, Kyushu, Japan) was investigated based on fossil shark teeth found at five localities: Himedo Park, Kugushima, Wadanohana, Higashiura, and Kotorigoe. A detailed geological survey and taxonomic analysis was undertaken, and the habitat, depositional environment, and associated mollusks of each locality were considered in the context of previous studies. Twenty-one species, 15 genera, 11 families, and 6 orders of fossil sharks are recognized from the localities. This assemblage is more diverse than has previously been reported for Japan, and Lamniformes and Hexanchiformes were abundant. Three categories of shark fauna are recognized: a coastal region (Himedo Park; probably a breeding site), the coast to the open sea (Kugushima and Wadanohana), and bottom-dwelling or near-seafloor fauna (Kugushima, Wadanohana, Higashiura, and Kotorigoe).

A preliminary description is provided of a new assemblage of small, three-dimensional and char- coalified mesofossils from the Tamagawa Formation (late Turonian–middle Santonian; Upper Cretaceous) of the Kuji Group in northeastern Japan. The new mesofossils yield excellent structural details and include well- preserved circinate shoots of ferns together with conifer leafy-shoots, seeds and probable pollen cones, and vari- ety of angiosperm fruits and seeds, including fruits of Cornales and seeds of Nymphaeales. The new mesofossil assemblage is complementary to the previously published macrofossil flora from the Kuji Group.

Basal titanosauriforms were present in Japan during the Early Cretaceous before Aptian, and there is the possibility that the Brachiosauridae may have been included. Basal titanosauriforms with peg-like teeth were present during the “mid” Cretaceous, while the Titanosauria with peg-like teeth was present during the middle of Late Cretaceous. Recent excavations of Cretaceous sauropods in Asia showed that multiple lineages of sauropods lived throughout the Cretaceous in Asia. Japanese fossil records of sauropods are conformable with this hypothesis. Key words: Sauropod, Titanosauriforms, tooth, Cretaceous, Japan.

No part of this work has been submitted for any other academic award. 1 Acknowledgements At inception of this project there was a significant risk that the Wessex Formation would not yield a microvertebrate fauna. I would, therefore, like to express special thanks to Dave Martill (University of Portsmouth) for his initial support and for securing the research scholarship which made this study possible. I would also like to thank him for his supervision, generous support, encouragement and advice thereafter. Special thanks also to Susan Evans (UCL) for her enthusiastic help and advice on all matters relating to microvertebrates in general, and lizards in particular, and to Jerry Hooker (NHM) for everything relating to mammals; also to Brian Gasson for his support in the field and for the generous donation of many exceptional specimens from his private collection. The broad scope of this study has engendered the help, support and advice of many others and I am grateful to all. At the University

Three facies of bone-bearing beds (Facies I: carbonaceous sandstones; Facies II: dark grey fine-grained silty sandstones; Facies III: dark greenish-grey mudstones) are present in inter-channel deposits that originated on a floodplain. The grain size of the sediments, and plant and molluscan fossils occurring in each bone-bearing bed, indicate that Facies I was deposited in a peat marsh, Facies II in a shallow lake, and Facies III in a vegetated swamp. Isolated small bones and teeth are the most abundant vertebrate fossils. Common elements in Facies II are aquatic vertebratessuch as fishes and turtles.
