Correlation of Tethyan and Boreal Berriasian – Barremian Strata with Emphasis on Strata in the Subsurface of the Netherlands Cretaceous Research 24 (2003) 253–275 Correlation of Tethyan and Boreal Berriasian – Barremian strata with emphasis on strata in the subsurface of the Netherlands Philip J. Hoedemaekera*, G.F. Waldemar Herngreenb a National Museum of Natural History, PO Box 9517, 2300 RA, Leiden Netherlands b Netherlands Institute of Applied Geoscience TNO – National Geological Survey, Utrecht Netherlands; present address: Laboratory of Palaeobotany and Palynology, Budapestlaan 4, 3584 CD Utrecht, Netherlands Accepted 4 April 2003 Abstract The standard Tethyan Berriasian–Barremian successions of France and Spain are correlated with the Boreal successions of England, Germany and the Netherlands. Special emphasis is placed on the correlation and sequence stratigraphy of the main hydrocarbon-producing strata of the Berriasian–Barremian stages in the four main basins in the subsurface of the Netherlands and the Dutch part of the North Sea continental shelf. All available biostratigraphic, magnetostratigraphic, and sequence-stratigraphic correlation data-sets were used to draw this correlation chart. Many lacunae in shallow marine successions could be correlated with sediments in deeper marine successions. Some sequence boundaries are tectonically enhanced and were accompanied by extra large falls in sea level; they initiated important changes in the biota and sedimentary regimes of western Europe, viz, the boundaries of the so-called ‘transgressive regressive facies cycles’ of Jacquin & de Graciansky. 2003 Elsevier Ltd.

  • The Barremian Heteromorph Ammonite Dissimilites from Northern Italy: Taxonomy and Evolutionary Implications
    The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxonomy and evolutionary implications ALEXANDER LUKENEDER and SUSANNE LUKENEDER Lukeneder, A. and Lukeneder, S. 2014. The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxon- omy and evolutionary implications. Acta Palaeontologica Polonica 59 (3): 663–680. A new acrioceratid ammonite, Dissimilites intermedius sp. nov., from the Barremian (Lower Cretaceous) of the Puez area (Dolomites, northern Italy) is described. Dissimilites intermedius sp. nov. is an intermediate form between D. dissimilis and D. trinodosum. The new species combines the ribbing style of D. dissimilis (bifurcating with intercalating single ribs) with the tuberculation style of D. trinodosum (trituberculation on entire shell). The shallow-helical spire, entirely comprising single ribs intercalated by trituberculated main ribs, is similar to the one of the assumed ancestor Acrioceras, whereas the increasing curvation of the younger forms resembles similar patterns observed in the descendant Toxoc- eratoides. These characters support the hypothesis of a direct evolutionary lineage from Acrioceras via Dissimilites to Toxoceratoides. D. intermedius sp. nov. ranges from the upper Lower Barremian (Moutoniceras moutonianum Zone) to the lower Upper Barremian (Toxancyloceras vandenheckii Zone). The new species allows to better understand the evolu- tion of the genus Dissimilites. The genus appears within the Nicklesia pulchella Zone represented by D. duboise, which most likely evolved into D. dissimilis. In the Kotetishvilia compressissima Zone, two morphological forms developed: smaller forms very similar to Acrioceras and forms with very long shaft and juvenile spire like in D. intermedius sp. nov. The latter most likely gave rise to D. subalternatus and D. trinodosum in the M.

  • The Giant Pliosaurid That Wasn't—Revising the Marine Reptiles From
    The giant pliosaurid that wasn’t—revising the marine reptiles from the Kimmeridgian, Upper Jurassic, of Krzyżanowice, Poland DANIEL MADZIA, TOMASZ SZCZYGIELSKI, and ANDRZEJ S. WOLNIEWICZ Madzia, D., Szczygielski, T., and Wolniewicz, A.S. 2021. The giant pliosaurid that wasn’t—revising the marine reptiles from the Kimmeridgian, Upper Jurassic, of Krzyżanowice, Poland. Acta Palaeontologica Polonica 66 (1): 99–129. Marine reptiles from the Upper Jurassic of Central Europe are rare and often fragmentary, which hinders their precise taxonomic identification and their placement in a palaeobiogeographic context. Recent fieldwork in the Kimmeridgian of Krzyżanowice, Poland, a locality known from turtle remains originally discovered in the 1960s, has reportedly provided additional fossils thought to indicate the presence of a more diverse marine reptile assemblage, including giant pliosaurids, plesiosauroids, and thalattosuchians. Based on its taxonomic composition, the marine tetrapod fauna from Krzyżanowice was argued to represent part of the “Matyja-Wierzbowski Line”—a newly proposed palaeobiogeographic belt comprising faunal components transitional between those of the Boreal and Mediterranean marine provinces. Here, we provide a de- tailed re-description of the marine reptile material from Krzyżanowice and reassess its taxonomy. The turtle remains are proposed to represent a “plesiochelyid” thalassochelydian (Craspedochelys? sp.) and the plesiosauroid vertebral centrum likely belongs to a cryptoclidid. However, qualitative assessment and quantitative analysis of the jaws originally referred to the colossal pliosaurid Pliosaurus clearly demonstrate a metriorhynchid thalattosuchian affinity. Furthermore, these me- triorhynchid jaws were likely found at a different, currently indeterminate, locality. A tooth crown previously identified as belonging to the thalattosuchian Machimosaurus is here considered to represent an indeterminate vertebrate.

  • Highly Derived Eutherian Mammals from the Earliest Cretaceous of Southern Britain
    Editors' choice Highly derived eutherian mammals from the earliest Cretaceous of southern Britain STEVEN C. SWEETMAN, GRANT SMITH, and DAVID M. MARTILL Sweetman, S.C., Smith, G., and Martill, D.M. 2017. Highly derived eutherian mammals from the earliest Cretaceous of southern Britain. Acta Palaeontologica Polonica 62 (4): 657–665. Eutherian mammals (Placentalia and all mammals phylogenetically closer to placentals than to marsupials) comprise the vast majority of extant Mammalia. Among these there is a phenomenal range of forms and sizes, but the origins of crown group placentals are obscure. They lie within the generally tiny mammals of the Mesozoic, represented for the most part by isolated teeth and jaws, and there is strongly conflicting evidence from phenomic and molecular data as to the date of origin of both Eutheria and Placentalia. The oldest purported eutherians are Juramaia from the Upper Jurassic of China, and Eomaia and Acristatherium from the Lower Cretaceous, also of China. Based on dental characters and analyses of other morphological and molecular data, doubt has recently been cast on the eutherian affinities of the Chinese taxa and consequently on the date of emergence of Eutheria. Until now, the only tribosphenic mammal recorded from the earliest Cretaceous (Berriasian) Purbeck Group of Britain was the stem tribosphenidan Tribactonodon. Here we document two new tribosphenic mammals from the Purbeck Group, Durlstotherium gen. nov. and Durlstodon gen. nov., showing highly derived eutherian molar characters that support the early emergence of this clade, prior to the Cretaceous.

La position stratigraphique de Paracrioceras giraudae sp. nov. n’a pas été précisée lors de sa mise en collection. Cette espèce est, comme les autres espèces du genre Paracrioceras Spath, 1924, située dans le Barrémien inférieur, dans la Zone à Kotetishvilia nicklesi. C’est à partir du genre Criosarasinella Thieuloy, 1977 du Valanginien supérieur, qu’apparaissent les Crioceratitidae Gill, 1871 et en particulier le genre Crioceratites Leveille, 1837 dont les espèces les plus anciennes apparaissent dans l’Hauterivien inférieur. Sur le plan stratigraphique, entre les différentes espèces de ces deux genres apparaissent des espèces intermédiaires dont l’association des caractères morpho- logiques des spécimens ne permettent pas de les classer totalement ni dans le genre Criosarasinella Thieuloy, 1977 ni dans le genre Crioceratites Leveille, 1837.

  • From the Portland and Purbeck Groups (Tithonian–Berriasian) of Dorset, United Kingdom
    New thoracican cirripedes (Crustacea) from the Portland and Purbeck Groups (Tithonian–Berriasian) of Dorset, United Kingdom Andy Galea aSchool of Earth and Environmental Sciences, University of Portsmouth, Burnaby Building, Burnaby Road, Portsmouth PO1 3QL, United Kingdom E-mail: [email protected] Abstract. The first cirripedes from the Portland and Purbeck groups of southern England are described, and referred to two new species, Loriolepas whytei sp. nov and Etcheslepas portlandensis sp. nov. They constitute the first records of cirripedes from the upper Tithonian (uppermost Jurassic) and Berriasian (lowermost Cretaceous) of western Europe. A new family, the Archaeolepadidae, is introduced for the extinct genera Archaeolepas and Loriolepas. Key words. Jurassic, Cretaceous, stalked barnacles, southern England Introduction In 1928, Thomas Withers described the meagre cirripede material from the British Upper Jurassic, consisting of a small number of mostly broken valves washed from the Kimmeridge Clay of Buckinghamshire. In the Lower Cretaceous, the marine pre-Aptian strata had yielded only a single species from the Speeton Clay (Hauterivian) of Speeton, Yorkshire. Recent discoveries by Steve Etches (Etches Collection, Kimmeridge) of magnificently preserved, and locally abundant, cirripedes from the Kimmeridge Clay in Dorset have considerably improved our understanding of the taxonomy, phylogeny and palaeoecology of Late Jurassic forms (Gale 2014, 2018), but they remained unknown from the overlying Portland Group. In 2015, during a field excursion for students of the University of Portsmouth to Freshwater, on the Isle of Portland (Fig. 1) I collected a number of cirripede valves from the Cherty Member of the Portland Stone Formation, and further specimens on a subsequent visit.

At Laghetto and Alpetto (Lombardy, Italy), Lower Aptian ammonites occur just above polarity zone M0 and below the Selli Level, and Upper Barremian ammonites occur in polarity zone Mln. These correlations are consistent with the Barremian/Aptian boundary being close to older boundary of (polarity chron) CM0. The uppermost Hauterivian ammonite (Faraoni) guide level has been correlated to CM4 at Bosso (Umbria-Marche), confirming the recent correlation of the Hauterivian/Barremian boundary to CM4. At Monte Acuto (Umbria-Marche), ammonites spanning the Valanginian/Hauterivian boundary interval, and the last appearance of the nannofossil T. verenae, occur close to the CMll/CMlln boundary. The Valanginian/Hauterivian boundary has previously been placed between the first appearance of L. bollii and the last appearance of T. verenae, or between CM10 and CMll. The published Polaveno (Lombardy) magnetostratigraphy for the CM3-CMll interval has now been extended to CM16. This 260 m section, recording the CM3-CM16 interval, is the most complete single-section record of Cretaceous M-sequence polarity chrons.

  • Aspects of the Microvertebrate Fauna of the Early Cretaceous (Barremian) Wessex Formation of the Isle of Wight, Southern England
    ASPECTS OF THE MICROVERTEBRATE FAUNA OF THE EARLY CRETACEOUS (BARREMIAN) WESSEX FORMATION OF THE ISLE OF WIGHT, SOUTHERN ENGLAND By STEVEN CHARLES SWEETMAN M.A. (Oxon.) 1980 F.G.S. A thesis submitted in partial fulfilment of the requirements for the award of the degree of Doctor of Philosophy of the University of Portsmouth School of Earth and Environmental Sciences, University of Portsmouth, Burnaby Building, Burnaby Road, Portsmouth, PO1 3QL, U.K. April, 2007 0 Disclaimer Whilst registered for this degree, I have not registered for any other award. No part of this work has been submitted for any other academic award. 1 Acknowledgements At inception of this project there was a significant risk that the Wessex Formation would not yield a microvertebrate fauna. I would, therefore, like to express special thanks to Dave Martill (University of Portsmouth) for his initial support and for securing the research scholarship which made this study possible. I would also like to thank him for his supervision, generous support, encouragement and advice thereafter. Special thanks also to Susan Evans (UCL) for her enthusiastic help and advice on all matters relating to microvertebrates in general, and lizards in particular, and to Jerry Hooker (NHM) for everything relating to mammals; also to Brian Gasson for his support in the field and for the generous donation of many exceptional specimens from his private collection. The broad scope of this study has engendered the help, support and advice of many others and I am grateful to all. At the University
