Waller Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC 20013-7012 USA, email [email protected] ABSTRACT Based on approximately 25,000 specimens from the Miocene and Pliocene of the Cibao Valley, northern Dominican Republic, the bivalve family Propeamussiidae is represented by two genera and four species, including two new species, Cyclopecten acuminatus and C. zalaya; the family Pectinidae is represented by three subfamilies, six tribes, 18 genera, and 35 species. New taxa in the Pectinidae include six new genera (Interchlamys, Chagrepecten, Gurabopecten, Paraleptopecten, Zamorapecten, and Antillipecten), 15 new species (Caribachlamys guayubinensis, C. jungi, Mimachlamys blowi, M. vokesorum, Palliolum? cibaoense, Argopecten parathetidis, Chagrepecten paracactaceus, Gurabopecten uniplicatus, Lindapecten baitoaensis, L. paramuscosus, Euvola gurabensis, Zamorapecten maoensis, Antillipecten janicoensis, A. microlineatus, and A. quemadosensis), one species in open nomenclature (Paraleptopecten sp. a), and one new subspecies (Argopecten eccentricus lacabrensis). In addition, a new name, Euvola jamaicensis, replaces the name E. barretti (Woodring, 1925). Lectotypes are designated for Cyclopecten guppyi (Dall, 1898) and Cryptopecten phrygium (Dall, 1886). Four of the genera (20%) and all but four of the species (90%) in the two families are extinct. Among the Pectinidae, 60% of the species but only 5% of the genera are endemic to the northern Dominican Republic. Th e high species endemism is possibly an artifact due to the absence in many other regions of precisely correlative strata as well as to diff erences in facies and sampling methods. Assemblages of the two families change composition going upward in stratigraphic sections measured along each major river, refl ecting increasing depth of deposition, changing bottom conditions, and association with coral reefs or marine grasses and algae. Evolutionary changes within particular lineages help to resolve several previous biostratigraphic uncertainties and controversies, including the age of limestones on the Río Yaque del Norte and in the Guayubín area. Detailed study of these changes has also shed new light on the causes of dramatic faunal diff erences between stratigraphic sections on the Río Gurabo and Río Mao, separated by only 10 km. RESUMEN El estudio de aproximadamente 25,000 ejemplares del Mioceno y Plioceno marino del Valle del Cibao, en el norte de la República Dominicana, nos permite indicar que la familia de bivalvos Propeamussiidae está representada por dos géneros y cuatro especies, dos de ellas especies nuevas, Cyclopecten acuminatus y C. zalaya, y que la familia Pectinidae está representada por tres subfamilias, seis tribus, 18 géneros y 35 especies. Los taxones nuevos de Pectinidae incluyen seis géneros nuevos (Interchlamys, Chagrepecten, Gurabopecten, Paraleptopecten, Zamorapecten y Antillipecten), 15 especies nuevas (Caribachlamys guayubinensis, C. jungi, Mimachlamys blowi, M. vokesorum, Palliolum? cibaoense, Argopecten parathetidis, Chagrepecten pa- racactaceus, Gurabopecten uniplicatus, Lindapecten baitoaensis, L. paramuscosus, Euvola gurabensis, Zamorapecten maoensis, Antillipecten janicoensis, A. microlineatus y A. quemadosensis), una especie en nomenclatura abierta (Paraleptopecten specides a) y una subespecie nueva (Argopecten eccenttricus lacabrensis). Además, un nombre nuevo, Euvola jamaicensis, reemplaza el nombre E. barretti (Woodring, 1925). Lectotipos de Cyclopecten guppyi (Dall, 1998) y Cryptopecten phrygium (Dall, 1886) son designados. Cuatro de los géneros (20%) y todas de las especies excepto cuatro (90%) en las dos familias, están extintas. Entre los Pectinidae, 60% de las especies pero solamente 5% de los géneros son endémicos para el norte de la República Dominicana. El alto endemismo de las especies posiblemente es un artefacto parcialmente causado por la ausencia de estratos exactamente correlacionados en muchas otras regiones asi como por diferencias en las facies y en los métodos de muestreo. Los asociasiones de las especies cambian en su composición a lo largo de cada río principa a medida que ascendemos es- tratigrafi camente, lo que refl eja aumentos en la profundidad de deposición, cambios en las condiciones del fondo y el grado de asociación con los arrecifes de coral o los céspedes marinos y las algas. Los cambios evolutivos en algonos llinajes nos permiten solucionar algunas incertidumbres estratigráfi cas y controversias, incluyendo la edad de las calizas en el Río Yaque del Norte y en la region de Guayubín. El estudio detallado de estos cambios nos ha permitido iluminar las causas de las diff erencias faunisticas grandes entre las secciones estratigráfi cas del Río Gurabo y el Río Mao, los que están separados por solamente 10 km. 2 Bulletins of American Paleontology, No. INTRODUCTION are commonly well preserved in the fossil record.

  • Introduction San Andreas Fault: an Overview

    Introduction San Andreas Fault: an Overview

    Introduction This volume is a general geology field guide to the San Andreas Fault in the San Francisco Bay Area. The first section provides a brief overview of the San Andreas Fault in context to regional California geology, the Bay Area, and earthquake history with emphasis of the section of the fault that ruptured in the Great San Francisco Earthquake of 1906. This first section also contains information useful for discussion and making field observations associated with fault- related landforms, landslides and mass-wasting features, and the plant ecology in the study region. The second section contains field trips and recommended hikes on public lands in the Santa Cruz Mountains, along the San Mateo Coast, and at Point Reyes National Seashore. These trips provide access to the San Andreas Fault and associated faults, and to significant rock exposures and landforms in the vicinity. Note that more stops are provided in each of the sections than might be possible to visit in a day. The extra material is intended to provide optional choices to visit in a region with a wealth of natural resources, and to support discussions and provide information about additional field exploration in the Santa Cruz Mountains region. An early version of the guidebook was used in conjunction with the Pacific SEPM 2004 Fall Field Trip. Selected references provide a more technical and exhaustive overview of the fault system and geology in this field area; for instance, see USGS Professional Paper 1550-E (Wells, 2004). San Andreas Fault: An Overview The catastrophe caused by the 1906 earthquake in the San Francisco region started the study of earthquakes and California geology in earnest.

Wilson1, J. Zhang3,15 and N. J. Bax2,16 Abstract Background: Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over the last 150 years. In May–June 2017, the IN2017_V03 expedition of the RV Investigator sampled LBA benthic communities along the lower slope and abyss of Australia’s eastern margin from off mid-Tasmania (42°S) to the Coral Sea (23°S), with particular emphasis on describing and analysing patterns of biodiversity that occur within a newly declared network of offshore marine parks. Methods: The study design was to deploy a 4 m (metal) beam trawl and Brenke sled to collect samples on soft sediment substrata at the target seafloor depths of 2500 and 4000 m at every 1.5 degrees of latitude along the western boundary of the Tasman Sea from 42° to 23°S, traversing seven Australian Marine Parks.

Wet. 30.11.1971 SYSTEMATIC REVISION OF ENTOLIUM, PROPEAMUSSIUM (AMUSIIDAE) AND SYNCYCLONEMA (PECTINIDAE, BIVALVIA, MOLLUSCA) OF THE EUROPEAN BOREAL CRETACEOUS by Annie Dhondt (Brussels) (With 4 plates) SUMMARY The present paper contains a systematic revision of the genera Entolium and Propeamussium (Amusiidae) and Syncyclonema (Pectinidae, Bival- via, Mollusca) in European Cretaceous boréal seas. In Entolium two species are described, in Propeamussium one, and in Syncyclonema eight of which one (S. hagenowi) is new to science, two (S. gamsensis and 5. haggi) are renamed and a former variety is given spécifie status (S. haldonensis). Stress is laid on redefining the species, mostly along biological lines. Material has been studied from as many localities as possible; a nomen- clatorial critical revision is undertaken; type-specimens have been located; type-strata and type-localities are indicated. RESUME La présente étude contient la révision systématique des genres Entolium et Propeamussium (Amusiidae) et Syncyclonema (Pectinidae, Bivalvia, Mollusca) qui ont vécu dans les mers boréales du Crétacé d'Europe. Pour le genre Entolium, deux espèces sont décrites; pour le genre Pro¬ peamussium, une espèce est décrite; pour le genre Syncyclonema huit espèces sont décrites : de celles-ci une est nouvelle (S. hagenowi), deux autres ont reçu un nouveau nom (S. gamsensis & S. haggi) et une der- 2 A. DHONDT 47, 32 nière considérée jusqu'ici comme variété est élevée au rang d'espèce (S. haldonensis). Les espèces sont redéfinies d'après des critères biologiques; les spéci¬ mens étudiés viennent d'autant de localités que possible; une révision cri¬ tique de la nomenclature a été faite; les types ont été recherchés; les localités-types avec leur niveau stratigraphique sont indiquées.

    SMITHSONIAN INSTITUTION UNITED STATES NATIONAL MUSEUM Bulletin 156 ABORIGINAL INDIAN POTTERY OF THE DOMINICAN REPUBLIC BY HERBERT W. KRIEGER Curator of Ethnology, United States National Museum UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 1931 For sale by the Superintendent of Documents, Washington, D. C. Price, 75 cents ADVERTISEMENT The scientific publications of the National Museum include two series, known, respectively, as Proceedings and Bulletins. The Proceedings^ begun in 1878, are intended primarily as a me- dium for the publication of original papers, based on the collections of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and revisions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and scientific organiza- tions and to specialists and others interested in the different subjects. The dates at which these separate papers are published are recorded in the table of contents of each of the volumes. The Bulletins^ the first of which was issued in 1875, consist of a series of separate publications comprising monographs of large zoological groups and other general sj^stematic treatises (occasion- ally in several volumes), faunal works, reports of expeditions, cata- logues of type-specimens, special collections, and other material of a similar nature. The majority of the volumes are octavo in size, but a quarto size has been adopted in a few instances in which large plates were regarded as indispensable. In the Bulletin series appear volumes under the heading Gontrihutions from the United States National Hei'haHum^ in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum.
