    　View Summary

    A new species of Argillochelys (Testudines: Cryptodira: Cheloniidae). A. africana n. sp. is described on the basis of three skulls and a lower jaw from the Lower Tertiary beds of the Ouled Abdoun phosphate basin, Morocco. It differs from A. cuneiceps, A. antiqua and A. athersuchi essentially in the frontal well retracted from the orbital margin, with a broad prefrontal/prostorbital contact, a more developed secondary palate, and the anterior part of the lower jaw more dorsoventrally flattened, with a wider triturating surface and a longer symphysis, without lingual ridge. This is the first record of Argillochelys from Africa.

    　View Summary

    Osteopygis emarginatus Cope 1868 is described from the Lower Tertiary of the Ouled Abdoun phosphate basin, Morocco, on the basis of skulls and lower jaws. Osteopygis is a cosmopolitan turtle that had a wide geographical distribution during the Late Cretaceous and Paleocene. Osteopygis emarginatus is a very conservative species which crossed the Cretaceous/Tertiary boundary without major changes.

  • Turtle remains (Testudines, Chelonioidea) from the Middle Turonian of northwest Germany

    C. Diedrich, R. Hirayama

    Geologie en Mijnbouw/Netherlands Journal of Geosciences   82 ( 2 ) 161 - 167  2003

    　View Summary

    Turtle remains ascribed to the family Cheloniidae (Testudines, Cryptodira, Chelonioidea), collected from the lamarcki zone (Middle Turonian) at Wüllen (NW Germany) are described. The material consists of a right humerus, a scapula, a complete costalia, and costalia fragments of a single individual with the humerus indicating a primitive cheloniid of the 'toxochelyid grade'. The present material, as well as previously recorded chelonioid humeri from the Cenomanian and Turonian of Germany illustrate a progressive diversification of chelonioids during the early Late Cretaceous.

    　View Summary

    Abstract Chelonioid sea turtles (Order Testudinata
    Superfamily Chelonioidea) first appear in the early Cretaceous (Aptian‐Albian). Their long fossil record is excellent compared to most marine tetrapods. Nonetheless, there has been no inclusive attempt to provide an analysis of cladistic relationships among this group. In this paper, the following chelonioid classification is proposed, based on 76 characters among 20 fossil and six living well‐ represented genera: Family Cheloniidae (Coniacian to Recent)
    Toxochelys, Ctenochelys, Osteopygis, Erquelinnesia, Allopleuron, Argillochelys, Puppigerus, Eochelone, Syllomus, Natator, Eretmochelys, Chelonia, Caretta, Lepidochelys Family Protostegidae (Aptian to Maastrichtian?)

    Fossil turtles collected from the Sinda Beds of eastern Zaire contain three families. They are Erymnochelys sp. of family Pelomedusidae, gen. et sp. Indet. of family Carettochelyidae, and gen. et sp. indet of family Trionychidae. Among them is the first known occurrence from Africa of carettochelyid, the pig-nosed turtle, Erymnochelys, the bigheaded side necked turtle, while once flourished in African during Tertiary, is restricted to Madagascar, today. All of these are presumed to have had aquatic habitat in rivers and lakes.

    　View Summary

    We made paleontological and geological field works at the Late Miocene to Late Pliocene Irrawaddy sediments in central Myanmar, and found numerous vertebrate fossils including many primate fossils. As the result we elucidated that abrupt changes of the land mammal fauna during the Late Miocene probably because of the global aridification and expanding of grassland around 8 Ma.On the other hand, we analyzed the numerous isolated teeth discovered from the 14 Pleistocene cave deposits of the Guangxi Province, southern China, and revealed that multiple primate taxa were sympatrically distributed there since the Early Pleistocene and that the primate fauna changed drastically during the Middle to Late Pleistocene

    　View Summary

    We performed immunological assays on the extracts from eggshells of reptiles and birds. The results support that the archosaurian affinity of turtles. Raman measurements showed that eggshells of turtles are aragonite, whereas those of snakes, lizards, crocodiles and birds are calcite. We examined the ion composition in the secretions of the oviducts of soft-shelled turtles and hens. Under both the conditions, not aragonite but calcite is expected to be formed, suggesting that the switch between the polymorphs may be controlled by proteins

    　View Summary

    Through the project, 2062 specimens have been prepared and catalogued into the animal fossil collection at the Board of Education in Shiramine Village, Ishikawa Prefecture. Thirty-nine species and three morpho types of the egg shells have been recognized including 9species of molluscs, 4 species of fishes, one species of amphibian, 7 species of lizards, 3 species of turtles, 3 species of choristoderans, 6 species of dinosaurs, 2 species of pterosaurs, one species of birds, one species of synapsids, and two species of mammals. Among the fossil reptiles, a dolichosaur-like animal was identified for the first time outside of Europe/Middle East. It represents the earliest fossil record and the first occurrence in non-marine strata. The fossil is not congruent with a latest hypothesis that the snakes, dolichosaurs, and mosasaurs evoloved in the European/Middle Eastern sea in the Late Cretaceous. Among fossil fishes, a Phareodus-like fish was identified for the first time in Asia and it represents the earliest fossil record. This fossil questions a hypothesis that Phareodus and its related fishes were originated in the Southern Hemisphere in the Late Cretaceous. We organized an international symposium on the Early Cretaceous biota in East Asia at Kitakyushu City Museum of Natural History and Human History on 1 and 2 June. There were 15 papers including six given by overseas delegates. We produced a traveling exhibition on the Early Cretaceous Biota. It opened first at Chiba Prefectural Museum and Institute in the summer of 2002, and traveled to Gunma Museum of Natural History, and Kitakyushu City Museum of Natural History and Human History attracting more than 37300 visitors in total

    　千葉県袖ヶ浦市滝の口における第四紀清川層の陸生脊椎動物化石群の発掘調査は，兼子尚知（産総研）や千葉県立中央博物館のスタッフと提携しながら，１９９９年より延べ６０日以上におよぶ発掘作業をおこなってきた．昨年度は，４月２９日から５月３日にかけての発掘を最後に，現場での作業を終了した．平山は，清川層から産出したカメ類化石の分類とその意義について研究を進めてきたが，特定課題研究費によって購入したデジタルカメを活用することで，多量に採集された化石資料の整理が大いに進展した．その成果の一部は，昨年９月に千葉大学で開催された日本地質学会において『平山　廉・高橋亮雄・安川雄一郎．日本本土における第四紀カメ類動物相とその古生物地理学的・古環境学的意義』として報告された．　また，千葉県立中央博物館との連携により，清川層から産出した化石カメ類のうち，ヤベイシガメとハナガメ（いずれも絶滅種）に関して，それぞれ昨年１１月と今年１月に２度にわたってメディア向けの発表をおこない，多大な反響があった．今年２月２０日には，千葉県立中央博物館で清川層産の古生物学的成果に関するシンポジウムが開催され，その成果は年内に学術雑誌・第四紀研究に発表される予定である．特にハナガメについては，年内に新種としての記載論文を英文学術雑誌（日本古生物学会のPalaeontological Researchを予定）に出版する予定である．　なお１月１９日に発表したハナガメに関する記事は以下のようなWEBなどで紹介された．共同通信：Yahoo!ニュースhttp://headlines.yahoo.co.jp/hl?a=20050119-00000137-kyodo-soci毎日新聞：http://www.mainichi-msn.co.jp/kagaku/science/news/20050120k0000m040130000c.html
