Email: [email protected] Editor: Graciela S. Bressan y Diana E. Fernández Recibido: 12 de mayo de 2019 Aceptado: 2 de agosto de 2019 ABSTRACT Crustacean microcoprolites are abundant constituents in the Upper Jurassic–Lower Cretaceous of the Neuquén Basin (Argentina). A new record of these particles is described from the lowermost Olcostephanus (O.) atherstoni ammonite Zone (lower Valanginian) in the Mulichinco Formation at Puerta Curacó section, north of the Neuquén province. Coprolites come from shallow-water oyster-dominated biostromes and belong to a new ichnospecies, Palaxius chosmalalensis n. isp., which was previously described as P. decemlunulatus (Paréjas) from the Upper Cretaceous of Egypt. As a consequence of the description of the new ichnospecies, we propose to incor- porate quantitative criteria regarding the angle with which the canals are oriented, as well as its position with respect to the center of symmetry of the coprolite. Keywords: pellets, Callianassidae, ichnology, Cretaceous. RESUMEN Palaxius chosmalalensis n. isp., un nuevo microcoprolito de crustáceos del Cretácico Inferior de la Cuenca Neuquina, Argen- tina.

WIMBLEDON3 Key words: Ammonoidea, Ataxioceratidae, Himalayitidae, Neocomitidae, Upper Tithonian, Le Chouet, South-East France. Abstract. The aim of this paper is to document the ammonite fauna of the upper part of the Late Tithonian collected at the key section of Le Chouet (Drôme, SE France). Emphasis is laid on new and poorly known Ataxioceratidae, Himalayitidae and Neocomitidae from the upper part of the Tithonian. Among the Ataxioceratidae, a new account on the taxonomy and relationship between Paraulacosphinctes Schindewolf and Moravisphinctes Tavera is presented. Regarding the Himalayitidae, the range and content of Micracanthoceras Spath is discussed and two new genera are introduced: Ardesciella gen. nov., for a group of Mediterranean ammonites that is homoeomorphic with the Andean genus Corongoceras Spath, and Pratumidiscus gen. nov. for a specimen that shows morphological similarities with the Boreal genera Riasanites Spath and Riasanella Mitta. Finally, the occurrence of Neocomitidae in the uppermost Tithonian is documented by the presence of the reputedly Berriasian genera Busnardoiceras Tavera and Pseudargentiniceras Spath.

China Received 24 January 2007; accepted in revised form 14 May 2007 Available online 28 November 2007 Abstract Lithostratigraphic studies of the Upper JurassiceLower Cretaceous sedimentary successions exposed in the TingrieGyangze area, south- eastern Tibet resulted in the establishment of a revised stratigraphic framework. A major crustal fault separates the southern Tibetan sedimentary successions into a Southern Zone and a Northern Zone. The Upper JurassiceLower Cretaceous strata of the Southern Zone are subdivided into the Menkadun Formation (Oxfordian, Kimmeridgian, up to lower Upper Tithonian), the Gucuo Formation (Upper Tithonian to Lower Albian) and the overlying Dongshan Formation (Upper Albian). The Gucuo Formation is further subdivided into a quartz arenite unit, which is overlain by a shale unit, in turn overlain by a volcaniclastic sandstone unit. The youngest cluster of detrital zircon absolute age data (127.7 Æ 1.8 Ma) from the lower part of the volcaniclastic unit of the Gucuo Formation place the volcanic event before the Late Barremian. In the Northern Zone, the Upper JurassiceLower Cretaceous strata have been subdivided into four formations: the Zhera Formation (Upper Jurassic), the Weimei Formation (Tithonian), the Rilang Formation (?Berriasian) and the Gyabula Formation (? post-Valanginian).

    Stratigraphic Implications of a New Lower Cretaceous Ammonoid Fauna from the Puez Area (Valanginian – Aptian, Dolomites, Southern Alps, Italy)

    Geo.Alp, Vol. 3, S. 55–83, 2006 STRATIGRAPHIC IMPLICATIONS OF A NEW LOWER CRETACEOUS AMMONOID FAUNA FROM THE PUEZ AREA (VALANGINIAN – APTIAN, DOLOMITES, SOUTHERN ALPS, ITALY) Alexander Lukeneder1 & Christian Aspmair2 With 6 figures and 8 plates 1 Natural History Museum, Geological-Palaeontological Department, Burgring 7, A-1010 Wien, Austria, e-mail: [email protected] 2 Prissian 102, I – 39010 Tisens (BZ), Italy Abstract Lower Cretaceous ammonoids (n = 424) were collected at the Puez locality in the Dolomites of Southern Tyrol. The cephalopod fauna from the marly limestones to marls here indicates Late Valanginian to Early Aptian age. The deposition of the marly limestones and marls of this interval occurred during depositional- ly unstable conditions. The underlying Biancone Formation (Maiolica Formation) is of Early Valanginian, whereas the lowermost Rosso Ammonitico is of Jurassic to Berriasian age. The ammonoid fauna consists of 27 different genera, each represented by 1-2 species. The assemblage at the Puez section is dominated by the Phylloceratina (30%) and the Ammonitina (34%). Phyllopachyceras (17%) and Phylloceras (13%) (both Phylloceratina) are the most frequent components, followed by Lytoceras (12%) (Lytoceratina), and Barremites (10%) and Melchiorites (8%) (both Ammonitina). The cephalopod fauna is purely of Mediterranean origin. Zusammenfassung Unterkreide Ammonoideen (424 Exemplare) der Puez Lokalität in den Dolomiten Süd-Tirols wurden unter- sucht. Die Fauna der mergeligen Kalke und Mergel von Puez zeigen ein Alter von Ober-Valanginium bis Unter-Aptium an. Die mergeligen Kalke und Mergel dieses Abschnitts lagerten sich unter instabiler Bedingungen ab. Die unterlagernde Biancone Formation (Maiolica Formation) zeigt Unter-Valanginium an, wogegen die tiefste Formation des Rosso Ammonitico auf Ober-Jura bis Berriasium hindeutet.

The fossil specimens that have been collected so far are dispersed in museum collections around the world and some have been lost throughout the years. A reas- sessment of the fossil material stored in some of these museums’ collections has generated new data about the fossil-bearing lo- calities and greatly increased the number of formally identified specimens. The identified bone elements and taxa suggest a high vertebrate diversity dominated by actinopterygians and reptiles, including: long-necked plesiosaurs, pliosaurs, metriorhynchid crocodilians, pleurodiran turtles, ichthyosaurs, pterosaurs, and sauropod dinosaurs. This assemblage is commonly associated with unidentified remains of terrestrial plants and rare microor- ganisms, as well as numerous marine invertebrates such as am- monites, belemnites, pelecypods, brachiopods, and ostracods. This fossil assemblage is particularly valuable because it includes the most complete marine reptile record of a chronostratigraphic interval, which is poor in vertebrate remains elsewhere. In this contribution, the current status of the available vertebrate fossil specimens from the Late Jurassic of western Cuba is provided, along with a brief description of the fossil materials.

CONICET ‡Instituto de Investigación en Paleobiología y Geología, Universidad Nacional de Río Negro, 8332 General Roca, Río Negro, Argentina. CONICET (Received 12 September 2012; accepted 11 January 2013) Abstract – The oldest ophthalmosaurian records worldwide have been recovered from the Aalenian– Bajocian boundary of the Neuquén Basin in Central-West Argentina (Mendoza and Neuquén provinces). Although scarce, they document a poorly known period in the evolutionary history of parvipelvian ichthyosaurs. In this contribution we present updated information on these fossils, including a phylogenetic analysis, and a redescription of ‘Stenopterygius grandis’ Cabrera, 1939. Patagonian ichthyosaur occurrences indicate that during the Bajocian the Neuquén Basin palaeogulf, on the southern margins of the Palaeopacific Ocean, was inhabited by at least three morphologically discrete taxa: the slender Stenopterygius cayi, robust ophthalmosaurian Mollesaurus periallus and another indeterminate ichthyosaurian. Rib bone tissue structure indicates that rib cages of Bajocian ichthyosaurs included forms with dense rib microstructure (Mollesaurus) and forms with an ‘osteoporotic-like’ pattern (Stenopterygius cayi). Keywords: Mollesaurus,‘Stenopterygius grandis’, Middle Jurassic, Neuquén Basin, Argentina. 1. Introduction all Callovian and post-Callovian ichthyosaurs, two different Early Jurassic taxa have been proposed as Ichthyosaurs were one of the main predators in the ophthalmosaurian sister taxa: Stenopterygius (Maisch oceans all over the world during most of the Mesozoic & Matzke, 2000; Sander, 2000; Druckenmiller & (Massare, 1987).

    Diapsid Phylogeny and the Origin and Early Evolution of Squamates by Tiago Rodrigues Simões A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in SYSTEMATICS AND EVOLUTION Department of Biological Sciences University of Alberta © Tiago Rodrigues Simões, 2018 ABSTRACT Squamate reptiles comprise over 10,000 living species and hundreds of fossil species of lizards, snakes and amphisbaenians, with their origins dating back at least as far back as the Middle Jurassic. Despite this enormous diversity and a long evolutionary history, numerous fundamental questions remain to be answered regarding the early evolution and origin of this major clade of tetrapods. Such long-standing issues include identifying the oldest fossil squamate, when exactly did squamates originate, and why morphological and molecular analyses of squamate evolution have strong disagreements on fundamental aspects of the squamate tree of life. Additionally, despite much debate, there is no existing consensus over the composition of the Lepidosauromorpha (the clade that includes squamates and their sister taxon, the Rhynchocephalia), making the squamate origin problem part of a broader and more complex reptile phylogeny issue. In this thesis, I provide a series of taxonomic, phylogenetic, biogeographic and morpho-functional contributions to shed light on these problems. I describe a new taxon that overwhelms previous hypothesis of iguanian biogeography and evolution in Gondwana (Gueragama sulamericana). I re-describe and assess the functional morphology of some of the oldest known articulated lizards in the world (Eichstaettisaurus schroederi and Ardeosaurus digitatellus), providing clues to the ancestry of geckoes, and the early evolution of their scansorial behaviour.
