Recorded occurrences in the United States are plentiful; however, California seems to be an exception. Literature on Hesperotestudo in California is limited to faunal lists in papers, with few detailed descriptions. Here we review the literature on the genus, describe and identify specimens found in the upper Mehrten Formation (late Miocene-early Pliocene) exposed in the Central Valley of California at Turlock and Modesto Reservoirs, Stanislaus County, and address their implications for early Pliocene California biogeography and climate. All fossils described are from the collections of the University of California Museum of Paleontology (UCMP).

    ACT A P A L A E 0 ~ T 0 LOG I CA P 0 LON IC A Vol. IV I 9 5 9 No . 2 MARIAN MLYN ARSKI GLARICHELYS KNORRI (GRAY) - A CHELONIID FROM CARPATHIAN MENILITIC SHALES (POLAND) Abstract . - The fossil remains here described belonged to a young indiv id ual of Glarichelys knorri (Gray), a sea turtle. 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.

  • The First Oligocene Sea Turtle (Pan-Cheloniidae) Record of South America
    The first Oligocene sea turtle (Pan-Cheloniidae) record of South America Edwin Cadena1, Juan Abella2,3 and Maria Gregori2 1 Escuela de Ciencias Geológicas e Ingeniería, Yachay Tech, San Miguel de Urcuquí, Imbabura, Ecuador 2 Universidad Estatal de la Peninsula de Santa Elena, La Libertad, Santa Elena, Ecuador 3 Institut Català de Paleontologia Miquel Crusafont, Universitat Autónoma de Barcelona, Barcelona, Spain ABSTRACT The evolution and occurrence of fossil sea turtles at the Pacific margin of South America is poorly known and restricted to Neogene (Miocene/Pliocene) findings from the Pisco Formation, Peru. Here we report and describe the first record of Oligocene (late Oligocene, ∼24 Ma) Pan-Cheloniidae sea turtle remains of South America. The fossil material corresponds to a single, isolated and well-preserved costal bone found at the Montañita/Olón locality, Santa Elena Province, Ecuador. Comparisons with other Oligocene and extant representatives allow us to confirm that belongs to a sea turtle characterized by: lack of lateral ossification, allowing the dorsal exposure of the distal end of ribs; dorsal surface of bone sculptured, changing from dense vermiculation at the vertebral scute region to anastomosing pattern of grooves at the most lateral portion of the costal. This fossil finding shows the high potential that the Ecuadorian Oligocene outcrops have in order to explore the evolution and paleobiogeography distribution of sea turtles by the time that the Pacific and the Atlantic oceans were connected via the Panama basin.

  • The First Fossil Sea Turtles (Testudines: Cheloniidae)
    The first fossil sea turtles (Testudines: Cheloniidae) from the Cenozoic of Australia ERICH M. G. FITZGERALD and LESLEY KOOL FITZGERALD, E.M.G. & KOOL, L., XX.XX.2015. The first fossil sea turtles (Testudines: Cheloniidae) from the Cenozoic of Australia. Alcheringa 39, xxx–xxx. ISSN 0311-5518 An isolated dentary and costal identified as cf. Pacifichelys and Cheloniidae indet., respectively, are described from the upper Miocene–lower Plio- cene Black Rock Sandstone of Beaumaris, Victoria, Australia. These remains represent the first fossil evidence of sea turtles from the Cenozoic of Australia. Neither of the fossils can be referred to living genera, indicating that extinct cheloniids occurred in southeast Australian coastal waters for at least part of the late Neogene. Thus, the taxonomic composition of the current sea turtle fauna of Australia was apparently established within the last five to six million years. Erich M. G.

Box 37012, Washington DC 20013-7012, USA ABSTRACT—The seven species of extant sea turtles show a diversity of diets and feeding specializations. Some of these species represent distinctive ecomorphs that can be recognized by osteological characters and therefore can be identified in fossil taxa. Specifically, modifications to the feeding apparatus for shearing or crushing (durophagy) are easily recognizable in the cranium and jaw. New sea turtle fossils from the Miocene of Peru, described as a new genus and species (Pacifichelys urbinai n. gen. and n. sp.), correspond to the durophagous ecomorph. This new taxon is closely related to a recently described sea turtle from the middle Miocene of California, USA (Pacifichelys hutchisoni n. comb.), providing additional information on the osteological characters of this lineage.
