COLONIAL GEOLOGY AND MINERAL RESOURCES VOLUME 4, NUMBER 3 LONDON: HER MAJESTY'S STATIONERY OFFIC 1954 P R I r. E 7.r fitl N F. T SOME NEW UPPER CRETACEOUS AMMONITES FROM NIGERIA1 By R. A. REYMENT, B.Sc. Geological Survey Department, Nigeria Abstract THREE NEW AMMONITE GENERA AND A NUMBER OF AMMONITE SPECIES ARE DESCRIBED from the Turonian and Coniacian of Nigeria. The new genera are Onitshoce,.as of Desmoceratidae, Kamerunoceras of Collignoniceratidae and Ezilloella of Vasco ceratidae. Some new species of Pseudaspidoceras Hyatt, Gombeoceras Reyment, Pachyvascoce,.as Furon and Solgerites Reeside are recorded. A discussion of the family Vascoceratidae appears. · Introduction IN A RECENT PAPER (Reyment, 1954) some new genera of Lower Turonian ammonites from Nigeria were established and their types and a few other species briefly described. The present paper contains descriptions of two further species of one of these new genera and of species of associated genera that have a wide distribution in both southern and northern Nigeria. Three new genera from the Turonian and Coniacian of southern Nigeria and the Cameroons are treated. This paper also includes a brief discussion of the family Vascoceratidae which provides an important element of the Lower Turonian faunas of many areas in Africa, Europe, Asia and North and South America. Both this and the previous work are preliminary to a larger review of the Upper Cretaceous-ammonites of southern Nigeria that is in active preparation;· but whose publication will in,evitably be delayed. Mean while, it is hoped that the new gehera described below and the informa tion on taxonomy and phylogeny becoming a\7ailable from studies of the Nigerian faunas will be of value both to palaeontologists and strati graphers. -
Late Carboniferous Bryozoans from La Hermida, Spain
Late Carboniferous bryozoans from La Hermida, Spain Andrej Ernst and Elke Minwegen Acta Palaeontologica Polonica 51 (3), 2006: 569-588 Fifteen bryozoan species belonging to thirteen genera have been identified from an outcrop of the Picos de Europa Formation (Moscovian, Upper Carboniferous) at La Hermida in northern Spain. Three species and one genus are new Coscinium hermidensis sp. nov., Cystodictya pustulosa sp. nov., and Cystocladia hispanica gen. et sp. nov. Rhabdomesid bryozoans are the most diverse order with seven species, followed by cystoporids (four species), fenestellids (three species) and trepostomids (one species). Bryozoans with erect branched or reticulate colonies dominate in the studied assemblage; only two species possess encrusting colonies. Together with associated crinoids, the bryozoan assemblage indicates a subtidal environment below the zone of vigorous water movement. The La Hermida bryozoan fauna confirms the Upper Carboniferous age of the Picos de Europa Formation and allows various biogeographical interpretations. All previously known species of the genus Coscinium were reported from the Lower Permian of Russia. Clausotrypa monticola is known from the Lower Permian of Russia and Arctic as well as from the Upper Carboniferous of Carnic Alps (Austria). Rhabdomeson cf. propatulissimum and Penniretepora pseudotrilineata are known from the same level of Italian Carnic Alps. Streblotrypa (Streblascopora ) nikiforovae and Rhombocladia punctata are known from the Upper Carboniferous (Moscovian) of Ukraine. Fistulipora petaloida is known from Kasimovian Stage of Russian Plate. Several other species show connections with North America. Key words: Bryozoa, Cystoporida, Fenestellida, Carboniferous, Picos de Europa Formation, Spain.

By Frederick Chapman, A.L.S., F.G.S., Commonwealth Palaeon- tologist, and Francis A. Cudmore, Hon. Palaeontologist, National Museum. Plates XII-XV. Nearly 60 years ago Professor P. M. Duncan described the first Australian Cainozoic cidaroid before the Geological Society of London. During the next 20 years Professors R. Tate and J. W. Gregory published references to our fossil cidaroids, but further descriptive work was not attempted until the present authors undertook to examine the accumulated material in the National Museum, the Tate Collection at Adelaide University Museum, the Commonwealth Palaeontological Collection, and the private collections made by the late Dr. T. S. Hall, F. A. Singleton, the Rev. Geo. Cox and the authors. The classification of the Cidaridae is founded mainly upon living species and it is partly based on structures which are only rarely preserved in fossils. Fossil cidaroid tests are usually imperfect. On abraded tests the conjugation of ambulacral pores is obscure. The apical system is preserved only in one specimen among those examined. The spines are rarely attached to the test and pedicellariae are wanting. Therefore, in dealing with our specimens we have been guided mainly by the appear- ance and structure of ambulacral and interambulacral areas. Certain features used in our classification vary with the growth stage of the test : for instance, the number of coronal plates in vertical series, the number of ambulacral plates adjacent to the largest coronal plate, and sometimes the number of granules on the inner end of ambulacral plates. -

Valves of the brachylepadomorph cirripede Pycnolepas bruennichi Withers, 1914 are reported from the Early Palaeocene of the environs of Maastricht (The Netherlands and NE Belgium). The occurrenceof this distinctive species provides additional proof of a correlationof the with the in Maastricht Danish Danian Early Palaeocene the area. A discussion of the biostratigraphy of the Geulhem Member (Houthem Formation) from which the cirripede remains were collected is presented. It is concluded that P. bruennichi is restricted to strata of Palaeocene in Denmark well in the Early (Danian) age as as Maastrichtian type area (SE Netherlands, NE Belgium). John W.M.

G. 1, Davies Jaime 2 1 School of Natural Sciences; Trinity College Dublin; Dublin Ireland 2 Ifremer; Département LEP; Centre de Brest; Plouzané France * Corresponding author : Angela Stevenson, email address : [email protected] Abstract : Predation and competition are highly influential factors determining space use in foraging animals, and ultimately contribute to the spatial heterogeneity observed within habitats. Here we investigated the influence of competition and predation on space and resource use via continuous video transect observations – a tool that has not previously been employed for this purpose. This study therefore also evaluates video data as a pragmatic tool to study community interactions in the deep sea. Observations were compiled from 15 video transects spanning five submarine canyons in the Bay of Biscay, France. Substrate choice, positioning on the coral, echinoid aggregate size, and the presence/absence of predators (e.g. fish and decapods) as well as competitors (both inter- and intra-specific) were recorded. Two dominant co-existing echinoid taxa, echinothurids and Cidaris cidaris (3188 total observations), were observed in the study. For the echinothurids, no significant trends were detected in the inter- and intra-specific competition data. For Cidaris cidaris, significant shifts in substrate use were correlated to the presence of inter-specific competitors (echinothurids), whereby an increase in dead coral substrate usage was observed. -

In this paper I shall first refer to the circumstances under which the follow- ing observations were made. I had gone in the autumn of 1856 for a few weeks to Elie on the Fife coast, and was induced, as a means of relaxation and exercise in the open air, to pay some attention to the geology of the neighbourhood, resuming for a brief interval what was once a favourite pursuit. About a mile to the east of the village, I found a stratum well deserving attention—a thin bed of limestone—dipping in- land a little beyond the cliff on which stands the ruined Castle of Ardross. The fossil shells which it contained were of unusual form, and beautifully preserved ; there were fish remains of two or three species, and a small group of crustaceans still more remarkable. Among the fish I thought I could detect the large scales of an Irish species—the Holoirtijchius Fortlockii—and among the crustaceans there were the valves of Dithyrocaris, a genus particularly characteristic of the Irish beds. At once the question arose whether these fossils might not serve as links connecting this Ardross bed with the Irish series. -

Phylogeny, Diversity, and Ecology of the Ammonoid Superfamily Acanthoceratoidea Through the Cenomanian and Turonian
PHYLOGENY, DIVERSITY, AND ECOLOGY OF THE AMMONOID SUPERFAMILY ACANTHOCERATOIDEA THROUGH THE CENOMANIAN AND TURONIAN DAVID A.A. MERTZ A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE August 2017 Committee: Margaret Yacobucci, Advisor Andrew Gregory Keith Mann © 2017 David Mertz All Rights Reserved iii ABSTRACT Margaret Yacobucci Both increased extinction and decreased origination, caused by rising oceanic anoxia and decreased provincialism, respectively, have been proposed as the cause of the Cenomanian Turonian (C/T) extinction event for ammonoids. Conflicting evidence exists for whether diversity actually dropped across the C/T. This study used the ammonoid superfamily Acanthoceratoidea as a proxy for ammonoids as a whole, particularly focusing on genera found in the Western Interior Seaway (WIS) of North America, including Texas. Ultimately, this study set out to determine 1) whether standing diversity decreased across the C/T boundary in the WIS, 2) whether decreased speciation or increased extinction in ammonoids led to a drop in diversity in the C/T extinction event, 3) how ecology of acanthoceratoid genera changed in relation to the C/T extinction event, and 4) whether these ecological changes indicate rising anoxia as the cause of the extinction. In answering these questions, three phylogenetic analyses were run that recovered the families Acanthoceratidae, Collignoniceratidae, and Vascoceratidae. Pseudotissotiidae was not recovered at all, while Coilopoceratidae was recovered but reclassified as a subfamily of Vascoceratidae. Seven genera were reclassified into new families and one genus into a new subfamily. After calibrating the trees with stratigraphy, I was able to determine that standing diversity dropped modestly across the C/T boundary and the Early/Middle Turonian boundary.
