  • The Jurassic Pleurotomarioidean Gastropod Laevitomaria and Its Palaeobiogeographical History
    The Jurassic pleurotomarioidean gastropod Laevitomaria and its palaeobiogeographical history ROBERTO GATTO, STEFANO MONARI, JÁNOS SZABÓ, and MARIA ALESSANDRA CONTI Gatto, R., Monari, S., Szabó, J., and Conti, M.A. 2015. The Jurassic pleurotomarioidean gastropod Laevitomaria and its palaeobiogeographical history. Acta Palaeontologica Polonica 60 (1): 217–233. The genus Laevitomaria is reviewed and its palaeobiogeographical history is reconstructed based on the re-examination of its type species L. problematica, the study of material stored at the National Natural History Museum of Luxembourg, and an extensive review of the literature. The systematic study allows ascribing to Laevitomaria a number of Jurassic species from the western European region formerly included in other pleurotomariid genera. The following new combi- nations are proposed: Laevitomaria allionta, L. amyntas, L. angulba, L. asurai, L. daityai, L. fasciata, L. gyroplata, L. isarensis, L. joannis, L. repeliniana, L. stoddarti, L. subplatyspira, and L. zonata. The genus, which was once considered as endemic of the central part of the western Tethys, shows an evolutionary and palaeogeographical history consider- ably more complex than previously assumed. It first appeared in the Late Sinemurian in the northern belt of the central western Tethys involved in the Neotethyan rifting, where it experienced a first radiation followed by an abrupt decline of diversity in the Toarcian. Species diversity increased again during Toarcian–Aalenian times in the southernmost part of western European shelf and a major radiation occurred during the Middle Aalenian to Early Bajocian in the northern Paris Basin and southern England. After a latest Bajocian collapse of diversity, Laevitomaria disappeared from both the central part of western Tethys and the European shelf.

  • A Key Interval in the Early Mesozoic Phytoplankton Radiation
    1 The Bajocian (Middle Jurassic): a key interval in the early Mesozoic phytoplankton radiation 2 3 Nickolas J. Wiggan a.b*, James B. Riding b, Robert A. Fensome c, Emanuela Mattioli d 4 5 Insert addresses here 6 7 ABSTRACT 8 Dinoflagellates and coccolithophores are two of the most important groups of phytoplankton 9 in the modern oceans. These groups originated in the Triassic and radiated through the early 10 Mesozoic, rising to ecological prominence. Within this long-term radiation, important short- 11 term intervals of evolutionary and ecological change can be recognised. The Bajocian 12 (Middle Jurassic, ~170–168 Ma) was characterised by an important ecological transition 13 within the coccolithophores, and the radiation of one of the principal families of cyst-forming 14 dinoflagellates, the Gonyaulacaceae. During the Early Bajocian, the coccolith genus 15 Watznaueria diversified and expanded ecologically to dominate coccolith floras, a situation 16 which continued for the remainder of the Mesozoic. This pattern was paralleled within 17 dinoflagellate cyst floras by the ecological dominance of the genus Dissiliodinium in the mid- 18 palaeolatitudes. These phenomena appear to be linked to a positive carbon isotope shift, and 19 an interval of enhanced productivity driven by a shift to a more humid climate, enhanced 20 continental weathering and nutrient flux. The latest Early Bajocian to earliest Bathonian was 21 then characterised by the rapid increase in diversity of dinoflagellate cysts within the family 22 Gonyaulacaceae. Through this interval, the Gonyaulacaceae transitioned from being a 23 relatively minor component of dinoflagellate cyst floras, to becoming one of the prominent 24 groups of cyst-forming dinoflagellates, which has persisted to the Holocene.

  • Integrated Biostratigraphy Across the Aalenian/Bajocian Boundary of the Central High Atlas, Morocco
    Volumina Jurassica, 2015, Xiii (1): 27–42 Doi: 10.5604/17313708 .1148554 Integrated biostratigraphy across the Aalenian/Bajocian boundary of the Central High Atlas, Morocco Driss SADKI 1 Key words: Aalenian/Bajocian boundary, Central High Atlas, Morocco, integrated biostratigraphy. Abstract. This work presents an integrated biostratigraphic study across the Aalenian/Bajocian boundary of the Central High Atlas of Morocco. The data that are the basis for this study were obtained from the region of Rich that is located in the center of the basin of the Moroccan High Atlas. This region presents a thick Aalenian–Bajocian succession with continuous marine sedimentation, which offers a rich and varied fauna whose analysis enables the compilation of an integrated biostratigraphy based on the different paleontological groups: ammonites, belemnites, brachiopods, bivalves, gastropods, calcareous nanno- fossils, foraminifera and ostracods. INTRODUCTION AMMONITES The Rich area, situated in the center of the basin of High The succession of ammonite faunas in the interval across Moroccan Atlas (Fig. 1), presents a thick Aalenian–Bajocian the Aalenian/Bajocian boundary, shows (Fig. 2) six succes- succession with continuous marine sedimentation, which of- sive assemblages (Sadki, Elmi, 1991), sometimes dominated fers rich and varied fossils. This section was proposed as the by the NW European graphoceratids, sometimes by Mediter- auxiliary stratotype of the Aalenian/Bajocian boundary in the ranean Province taxa. Furthermore the abundance of the Mediterranean Province (Sadki, 1994).

    Aulacostephanid ammonites from the Kimmeridgian (Upper Jurassic) of British Columbia (western Canada) and their significance for correlation and palaeobiogeography MIKHAIL A. ROGOV & TERRY P. POULTON We present the first description of aulacostephanid (Perisphinctoidea) ammonites from the Kimmeridgian of Canada, and the first illustration of these ammonites in the Americas. These ammonites include Rasenia ex gr. cymodoce, Zenostephanus (Xenostephanoides) thurrelli, and Zonovia sp. A from British Columbia (western Canada). They belong to genera that are widely distributed in the subboreal Eurasian Arctic and Northwest Europe, and they also occur even in those Boreal regions dominated by cardioceratids. They are important markers for a narrow stratigraphic interval in the Cymodoce Zone (top of Lower Kimmeridgian) and the lower part of the Mutabilis Zone (base of Upper Kimmeridgian) of the Northwest European standard succession. In Spitsbergen and Franz Josef Land, the only Upper Kimmeridgian aulacostephanid-bearing level is the Zenostephanus (Zenostephanus) sachsi biohorizon, which very likely belongs to the Mutabilis Zone. Expansion of Zenostephanus from Eurasia, where it is present over a large area, into British Columbia, is approximately correlative with a transgressive event that also led to expansion of the Submediterranean ammonite ge- nus Crussoliceras through the Submediterranean and Subboreal areas slightly before Zenostephanus. • Key words: Kimmeridgian, aulacostephanids, Zenostephanus, Rasenia, British Columbia, palaeobiogeography, sea-level changes.

  • Earliest Known Lepisosteoid Extends the Range of Anatomically Modern Gars to the Late Jurassic Received: 25 September 2017 Paulo M
    www.nature.com/scientificreports OPEN Earliest known lepisosteoid extends the range of anatomically modern gars to the Late Jurassic Received: 25 September 2017 Paulo M. Brito1, Jésus Alvarado-Ortega2 & François J. Meunier3 Accepted: 2 December 2017 Lepisosteoids are known for their evolutionary conservatism, and their body plan can be traced at Published: xx xx xxxx least as far back as the Early Cretaceous, by which point two families had diverged: Lepisosteidae, known since the Late Cretaceous and including all living species and various fossils from all continents, except Antarctica and Australia, and Obaichthyidae, restricted to the Cretaceous of northeastern Brazil and Morocco. Until now, the oldest known lepisosteoids were the obaichthyids, which show general neopterygian features lost or transformed in lepisosteids. Here we describe the earliest known lepisosteoid (Nhanulepisosteus mexicanus gen. and sp. nov.) from the Upper Jurassic (Kimmeridgian – about 157 Myr), of the Tlaxiaco Basin, Mexico. The new taxon is based on disarticulated cranial pieces, preserved three-dimensionally, as well as on scales. Nhanulepisosteus is recovered as the sister taxon of the rest of the Lepisosteidae. This extends the chronological range of lepisosteoids by about 46 Myr and of the lepisosteids by about 57 Myr, and flls a major morphological gap in current understanding the early diversifcation of this group. Actinopterygians, or ray-finned fishes, are the largest group among extant gnathostoms vertebrates. Today actinopterygians are represented by three major clades: Cladistia (bichirs and rope fsh), with at least 16 species, Chondrostei (sturgeons and paddle fshes), with about 30 species, and Neopterygii, formed by the Teleostei, with about 30,000 species and the Holostei with eight species: one halecomorph (bowfn) and 7 ginglymodians (gars)1.

  • The Graphoceratid Ammonite Succession in the Aalenian and Lowest Bajocian (Middle Jurassic) at Horn Park, Dorset, UK ROBERT B
    The Graphoceratid Ammonite Succession in the Aalenian and lowest Bajocian (Middle Jurassic) at Horn Park, Dorset, UK ROBERT B. CHANDLER Riddlesdown High School, Purley, Surrey, CR8 lEX Summary In 1990 Callomon and Chandler set out a scheme of 16 faunal horizons for the Aalenian-Lower Bajocian of Dorset and Somerset based principally on graphoceratid ammonites. One locality, Horn Park, stands apart in displaying strata from almost all the horizons identified in that work. Yet little material from it has ever been figured. Here a section is given together with exhaustive tables of existing nominal morphospecies collected at each level and with figures that allow the variability of the suc- cessive, probably in most cases, monobiospecific assemblages to be assessed. A revised generic classification of the Graphoceratidae is presented. them precludes almost any satisfactory discussion of phyletic relationships and hence of the overall evolution The highly discontinuous, condensed and rapidly of the group. varying development of the Inferior Oolite in southern England was first perceived by S.S. Buckman (e.g. 1891, The biostratigraphy of the Graphoceratidae has now 1893, 1910) during his attempts to correlate sections by been rather well documented, for example by Rocha et means of ammonites. Leading amongst these in al. (1990), Henriques (1992; et al. 1994) in Portugal; the Aalenian part of the succession are the Linares and Sandoval (1990) in Spain, Sadki (1994) in Graphoceratidae, including such well known genera as Morocco. In Britain, Morton (1990; 1994) and Morton Leioceras, Ludwigia, Brasilia, Graphoceras and and Hudson (1995) have described the succession in Hyperlioceras. Scotland and compared it with Dorset (Morton and Chandler 1994).
