Russian Journal of Herpetology Vol. 9, No. 2, 2002, pp. 137 – 154 REVIEW OF MESOZOIC AND CENOZOIC SEA TURTLES FROM THE FORMER USSR Alexander O. Averianov1 Submitted December 17, 2001. A list of 51 localities of fossil sea turtles from the Middle Jurassic, Early and Late Cretaceous, Paleocene, Eocene and Miocene of Russia, Uzbekistan, Kazakhstan, Tajikistan, and Ukraine is provided. For four lo- calities in Tajikistan, Kazakhstan, and Ukraine presence of sea turtles is not confirmed by current data. Two new taxa, Dollochelys rogovichi sp.nov. (Cheloniidae, Eocene, Ukraine) and Turgaiscapha kushmu- runica gen. et sp.nov. (Chelonioidea indet., cf. Dermochelyidae, Late Cretaceous, Kazakhstan), are de- scribed. Key words: Cheloniidae, Chelonioidea, Dermochelyidae, Protostegidae, sea turtles, Thalassemydidae.

But contrary to the Jehol Biota which is rich in freshwater vertebrates, in the Yanliao Biota the aquatic reptiles are absent, and turtles have not been reported so far. In this paper, we report on the first turtle remains from the Yanliao Biota. The material consists of a partial skeleton from the Upper Jurassic Tiaojishan Formation of Bawanggou site (Qinglong, Hebei Province, China). Characterized by a broad skull with a pair of sulci carotici and a remnant of an interpterygoid vacuity, a well-developed anterior lobe of the plastron with mesiolaterally elongated epiplastra and a relatively large oval entoplastron; it is assigned to Annemys sp.

Xinjiangchelyids provide us with great insights into the plesiomorphic anatomy of crown-cryptodires, the most diverse group of living turtles, and they are particularly relevant for understanding the origin and early divergence of the primary clades of extant turtles. Results: Exceptionally complete new xinjiangchelyid material from the ?Qigu Formation of the Turpan Basin (Xinjiang Autonomous Province, China) provides new insights into the anatomy of this group and is assigned to Xinjiangchelys wusu n. sp. A phylogenetic analysis places Xinjiangchelys wusu n. sp. in a monophyletic polytomy with other xinjiangchelyids, including Xinjiangchelys junggarensis, X. radiplicatoides, X. levensis and X. latiens. However, the analysis supports the unorthodox, though tentative placement of xinjiangchelyids and sinemydids outside of crown-group Testudines. A particularly interesting new observation is that the skull of this xinjiangchelyid retains such primitive features as a reduced interpterygoid vacuity and basipterygoid processes.

Among the vertebrates, the turtles were proved quite diverse, with several specimens retrieved and five valid species described to this date for the Romualdo Fm.

They were collected from Carpathian me­ nilitic shales at Winnica near Jaslo. Its systematic position is discussed a nd general comments are made on some fossil and recent sea turtles, on problems concerning their mo rphology, on the taxonomic significance of p halanges in fossil sea turtles, a nd on the presence in cheloniids of foramina praenucha lia. Biological and ecological notes concernin g G. knorri (Gray) are likewise given. INTRODUCTlION The fossil sea turtle remains here described have been collected from an outcrop in the steep bank of the Jasiolka stream, near the Winnica farm, about 10 km to the east of Jaslo (P olish Carpathians). The specimen was found in greyish-brown menilitic shales intercalating the Kr osno sandstone beds, about 30 m above the foot of the men tioned bank. Unfortunately, the geological age of these beds has not, as yet, been definitely established. On their microfauna it is probably Lower Oligocene or Upper Eocene 1. The vertebrate fauna from the Jaslo area has lately attracted the attention of palaeontologists. Abundant and we ll preserved bon y fish remains have been collected there.They belong to several families, mostly to Clupeidae and Gadidae. They are n ow being worked out by A .J erz­ manska (1958) of the Wroclaw University.

Marcos Jannello 2018 Resumen Las inusuales estructuras óseas observadas entre los vertebrados, como el cuello largo de la jirafa o el cráneo en forma de T del tiburón martillo, han interesado a los científicos desde hace mucho tiempo. Uno de estos casos es el clado Testudinata el cual representa uno de los grupos más fascinantes y enigmáticos conocidos entre de los amniotas. Su inconfundible plan corporal, que ha persistido desde el Triásico tardío hasta la actualidad, se caracteriza por la presencia del caparazón, el cual encierra a las cinturas, tanto pectoral como pélvica, dentro de la caja torácica desarrollada. Esta estructura les ha permitido a las tortugas adaptarse con éxito a diversos ambientes (por ejemplo, terrestres, acuáticos continentales, marinos costeros e incluso marinos pelágicos). Su capacidad para habitar diferentes nichos ecológicos, su importante diversidad taxonómica y su plan corporal particular hacen de los Testudinata un modelo de estudio muy atrayente dentro de los vertebrados. Una disciplina que ha demostrado ser una herramienta muy importante para abordar varios temas relacionados al caparazón de las tortugas, es la paleohistología. Esta disciplina se ha involucrado en temas diversos tales como el origen del caparazón, el origen del desarrollo y mantenimiento de la ornamentación, la paleoecología y la sistemática.

Recently, a vertebrate assemblage of the Jehol ence of the Eosestheria (crustacean)–Ephemeropsis trisetalis Biota has been reported from the Early Cretaceous Heng- (mayfly insect)–Lycoptera (fish) community (T. Shao et al., tongshan Formation of Xingling Town, Meihekou City, Jilin 2017). Freshwater sinemydid turtles are among the most Province, China. It is dominated by the fishes Lycoptera and common tetrapod fossils of the Jehol Biota, which makes Sinamia and the sinemydid turtle Ordosemys.
