Magnetostratigraphy of the Lower Cretaceous Vectis Formation (Wealden Group) on the Isle of Wight, Southern England
Journal ofthe Geological Society, London, Vol. 145, 1988, pp. 351-360, 10 figs, 1 table. Printed in Northern Ireland Magnetostratigraphy of the Lower Cretaceous Vectis Formation (Wealden Group) on the Isle of Wight, Southern England M. KERTH* & E. A.HAILWOOD Department of Oceanography, The University of Southampton, Southampton S09 5NH, UK * Present address: Fach Geologie, Fachbereich 9, Universitat Gesamthochschule Essen, 0-4300 Essen, FRG Abstract: Magnetostratigraphic results are described from two sections within the Lower Cretaceous Vectis Formation (formerly Wealden Shales) of the Isle of Wight, Southern England. The sections are located at Shepherd's Chine and Yaverland, respectively. In both of these sections a reliably-established reverse polarity magnetozone, herein defined as the Vectis magnetozone, occurs within the Shepherd's Chine Member. This magnetozone has a thickness of some 15 m and its upper boundary is well defined in the Yaverland section but is obscured in the Shepherd'sChine Section dueto cliff slumping. The lower boundary iswell established in both sections and lies some 15m above the Barnes High SandstoneMember in the Shepherd'sChine section and 12m above this unit at Yaverland. This boundary provides a useful chron-stratigraphic datum. A comparison with established geomagnetic polarity timescales for the Cretaceous indicates that the Vectis magnetozone may be correlated either with Lower Aptian reverse polarity Chron CM-0 or with Lower Barremian Chron CM-l, with the former being the more likely. An important implication of this interpretation is that the base of the Aptian stage, as defined from Tethyan foraminiferal zones, must lie within the Vectis Formation,at least 25-30m beneaththe top of theShepherd's Chine Member, rather than at the top of this member as hitherto commonly accepted. -
Historic Environment Action Plan South-West Wight Coastal Zone
Island Heritage Service Historic Environment Action Plan South-West Wight Coastal Zone Isle of Wight County Archaeology and Historic Environment Service October 2008 01983 823810 archaeology @iow.gov.uk Iwight.com HEAP for South-West Wight Coastal Zone INTRODUCTION This HEAP Area has been defined on the basis of geology, topography land use and settlement patterns which differentiate it from other HEAP areas. Essential characteristics of the South-West Wight Coastal Zone include the long coastline and cliffs containing fossils and archaeological material, the pattern of historic lanes, tracks and boundaries, field patterns showing evidence of open-field enclosure, valley-floor land, historic villages, hamlets and dispersed farmsteads, and vernacular architecture. The Military Road provides a scenic and historically significant route along the coast. The settlements of Mottistone, Hulverstone, Brighstone and Shorwell straddle the boundary between this Area and the West Wight Downland Edge & Sandstone Ridge. Historically these settlements exploited both Areas. For the sake of convenience these settlements are described in the HEAP Area document for the West Wight Downland Edge & Sandstone Ridge even where they fall partially within this Area. However, they are also referred to in this HEAP document where appropriate. This document considers the most significant features of the historic landscape, the most important forces for change, and the key management issues. Actions particularly relevant to this Area are identified from those listed in the Isle of Wight HEAP Aims, Objectives and Actions. ANALYSIS AND ASSESSMENT Location, Geology and Topography • Occupies strip of land between West Wight Downland Edge & Sandstone Ridge and coast. • Coastline within this Area stretches from Compton to Shepherd’s Chine and comprises soft, eroding cliffs with areas of landslip. -

A Revised Taxonomy of the Iguanodont Dinosaur Genera and Species
ARTICLE IN PRESS + MODEL Cretaceous Research xx (2007) 1e25 www.elsevier.com/locate/CretRes A revised taxonomy of the iguanodont dinosaur genera and species Gregory S. Paul 3109 North Calvert Station, Side Apartment, Baltimore, MD 21218-3807, USA Received 20 April 2006; accepted in revised form 27 April 2007 Abstract Criteria for designating dinosaur genera are inconsistent; some very similar species are highly split at the generic level, other anatomically disparate species are united at the same rank. Since the mid-1800s the classic genus Iguanodon has become a taxonomic grab-bag containing species spanning most of the Early Cretaceous of the northern hemisphere. Recently the genus was radically redesignated when the type was shifted from nondiagnostic English Valanginian teeth to a complete skull and skeleton of the heavily built, semi-quadrupedal I. bernissartensis from much younger Belgian sediments, even though the latter is very different in form from the gracile skeletal remains described by Mantell. Currently, iguanodont remains from Europe are usually assigned to either robust I. bernissartensis or gracile I. atherfieldensis, regardless of lo- cation or stage. A stratigraphic analysis is combined with a character census that shows the European iguanodonts are markedly more morpho- logically divergent than other dinosaur genera, and some appear phylogenetically more derived than others. Two new genera and a new species have been or are named for the gracile iguanodonts of the Wealden Supergroup; strongly bipedal Mantellisaurus atherfieldensis Paul (2006. Turning the old into the new: a separate genus for the gracile iguanodont from the Wealden of England. In: Carpenter, K. (Ed.), Horns and Beaks: Ceratopsian and Ornithopod Dinosaurs. -

GEOLOGICAL SURVEY OF OHIO. VOL. I.—PART II. PALÆONTOLOGY. SECTION II. DESCRIPTIONS OF FOSSIL FISHES. BY J. S. NEWBERRY. Digital version copyrighted ©2012 by Don Chesnut. THE CLASSIFICATION AND GEOLOGICAL DISTRIBUTION OF OUR FOSSIL FISHES. So little is generally known in regard to American fossil fishes, that I have thought the notes which I now give upon some of them would be more interesting and intelligible if those into whose hands they will fall could have a more comprehensive view of this branch of palæontology than they afford. I shall therefore preface the descriptions which follow with a few words on the geological distribution of our Palæozoic fishes, and on the relations which they sustain to fossil forms found in other countries, and to living fishes. This seems the more necessary, as no summary of what is known of our fossil fishes has ever been given, and the literature of the subject is so scattered through scientific journals and the proceedings of learned societies, as to be practically inaccessible to most of those who will be readers of this report. I. THE ZOOLOGICAL RELATIONS OF OUR FOSSIL FISHES. To the common observer, the class of Fishes seems to be well defined and quite distin ct from all the other groups o f vertebrate animals; but the comparative anatomist finds in certain unusual and aberrant forms peculiarities of structure which link the Fishes to the Invertebrates below and Amphibians above, in such a way as to render it difficult, if not impossible, to draw the lines sharply between these great groups. -

Dentitions of Late Palaeozoic Orthacanthus species and new species of ?Xenacanthus (Chondrichthyes: Xenacanthiformes) from North America. Acta Geologica Polonica, 49 (3),215-266. Warszawa. Orthacanthus lateral teeth have paired, variably divergent, smooth, usually carinated labio-lingually compressed principal cusps separated by a central foramen; one or more intermediate cusps; and an api cal button on the base isolated from the cusps. Several thousand isolated teeth from Texas Artinskian bulk samples are used to define the heterodont dentitions of O. texensis and O. platypternus. The O. tex ensis tooth base has a labio-Iingual width greater than the anteromedial-posterolateral length, the basal tubercle is restricted to the thick labial margin, the principal cusps are serrated to varying degrees, and the posterior cusp is larger. The O. platypternus tooth base is longer than wide, its basal tubercle extends to the center, the labial margin is thin, serrations are absent on the principal cusps, the anterior cusp is larger, and a single intermediate cusp is present. More than two hundred isolated teeth from Nebraska (Gzhelian) and Pennsylvania (Asselian) provide a preliminary description of the heterodont dentition of O. compress us . The principal cusps are similar to O. -

DINOSAUR BOOKLET No. 2 Iguanodon Bernissartensis and Mantellisaurus Atherfieldensis
DINOSAUR BOOKLET No. 2 Iguanodon bernissartensis and Mantellisaurus atherfieldensis Description Iguanodon (pronounced 'Ig-wan-oh-don') was one of the first dinosaurs to be named. The name is derived from 'Iguana' - a type of modern reptile, and 'don' meaning tooth. Iguanodon is the name of a small group of dinosaurs within the much larger group called Iguanodontids; they were large herbivores, with a long tail for balance, and hind legs that were longer than their fore limbs. There were three large hooved toes on each foot, and four fingers and a thumb spike on each hand. The mouth had a battery of chewing teeth, and a boney beak in place of front teeth. Since its initial discovery in the early nineteenth century, and more detailed reconstructions after complete skeletons were found in a Belgian mine in 1878, we have been forced to re-evaluate its posture, shape and movement; and to look again at how it fits in with other members of the Iguanodontids. Fossil remains from the group show they existed from the late Jurassic through to the late Cretaceous. Here on the Isle of Wight it was once thought there were two basic species of Iguanodon; a larger form called Iguanodon bernissartensis, and a more graceful species called Iguanodon atherfieldensis. The first was named after the Belgian town where complete skeletons were found (Bernissart) and the latter from Atherfield on the south west coast of the Isle of Wight. However 1 more recently palaeontologist Gregory Paul has moved our smaller variety to a new genera, leaving us with only one Iguanodon but a new genera of Iguanodontid called Mantellisaurus atherfieldensis (named after Gideon Mantell) in its place. -

These populations are distinguished by 6 morphological characteristics. How- ever, they have high geographic variation, and it is quite difficult to distinguish among them. In the present study, we investigated the geographic distribution of the morphological and genetic characteristics of Corbula (Potamocorbula) spp. collected from the waters adjacent to Japan, Korea and San Francisco Bay, USA. Shell morphology was inferred through canonical discrimi- nant analysis (CDA) of 8 shell characteristics, and genetic characteristics were analysed using the DNA sequences of mitochondrial cytochrome c oxidase subunit 1 (CO1) and nuclear internal tran- scribed spacer 2 (ITS2) regions. The results of CDA showed that the samples from Ganghwa-do in western Korea could be clearly separated from those of all the other localities. The molecular phy- logenetic tree and haplotype network that were constructed from the CO1 and ITS2 regions, respectively, did not show clear groupings among the collected samples, except for 1 group com- posed of samples from Ganghwa-do. -
