Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998
Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998 Stephen A. Grabe Environmental Supervisor David J. Karlen Environmental Scientist II Christina M. Holden Environmental Scientist I Barbara Goetting Environmental Specialist I Thomas Dix Environmental Scientist II MARCH 2003 1 Environmental Protection Commission of Hillsborough County Richard Garrity, Ph.D. Executive Director Gerold Morrison, Ph.D. Director, Environmental Resources Management Division 2 INTRODUCTION The Environmental Protection Commission of Hillsborough County (EPCHC) has been collecting samples in Middle Tampa Bay 1993 as part of the bay-wide benthic monitoring program developed to (Tampa Bay National Estuary Program 1996). The original objectives of this program were to discern the ―health‖—or ―status‖-- of the bay’s sediments by developing a Benthic Index for Tampa Bay as well as evaluating sediment quality by means of Sediment Quality Assessment Guidelines (SQAGs). The Tampa Bay Estuary Program provided partial support for this monitoring. This report summarizes data collected during 1993-1998 from the Middle Tampa Bay segment of Tampa Bay. 3 METHODS Field Collection and Laboratory Procedures: A total of 127 stations (20 to 24 per year) were sampled during late summer/early fall ―Index Period‖ 1993-1998 (Appendix A). Sample locations were randomly selected from computer- generated coordinates. Benthic samples were collected using a Young grab sampler following the field protocols outlined in Courtney et al. (1993). Laboratory procedures followed the protocols set forth in Courtney et al. (1995). Data Analysis: Species richness, Shannon-Wiener diversity, and Evenness were calculated using PISCES Conservation Ltd.’s (2001) ―Species Diversity and Richness II‖ software. -

[email protected] ABSTRACT X-ray CT provides three-dimensional (3-D) representations of internal features of silicified caprinid bivalves from the Lower Cretaceous (Albian Stage) Edwards Forma- tion in Texas. This technique enables the specific identification of caprinid rudists that otherwise could only be identified by sectioning the specimen. The abundant Edwards species is Caprinuloidea perfecta because it has only two rows of polygonal canals on its ventral and anterior margins. Ontogeny of these unusual gregarious bivalves is also demonstrated by means of these images.

Barremian-Lower Aptian Qishn Formation, Haushi-Huqf Area, Oman: a New Outcrop Analogue for the Kharaib/Shu’Aiba Reservoirs
GeoArabia, Vol. 9, No. 1, 2004 Gulf PetroLink, Bahrain Barremian-lower Aptian Qishn Formation, Haushi-Huqf area, Oman: a new outcrop analogue for the Kharaib/Shu’aiba reservoirs Adrian Immenhauser, Heiko Hillgärtner, Ute Sattler, Giovanni Bertotti, Pascal Schoepfer, Peter Homewood, Volker Vahrenkamp, Thomas Steuber, Jean-Pierre Masse, Henk Droste, José Taal-van Koppen, Bram van der Kooij, Elisabeth van Bentum, Klaas Verwer, Eilard Hoogerduijn Strating, Wim Swinkels, Jeroen Peters, Ina Immenhauser-Potthast and Salim Al Maskery ABSTRACT Limestones of the middle Cretaceous Qishn Formation are exposed in the Haushi-Huqf area of Oman. These carbonates preserved reservoir properties due to shallow burial and an arid post-exhumation climate. This characteristic makes the Qishn Formation an excellent outcrop analogue for the Upper Kharaib and Lower Shu’aiba oil reservoirs in the Interior Oman basins. The aim of this paper is to provide a broad overview of results from an industry-oriented field study recently performed in the Qishn Formation outcrops belts. The comparison of these results with studies undertaken in the Northern Oman Mountains and the Oman Interior subsurface is the topic of ongoing research. The age of the Qishn Formation is middle Barremian to mid-early Aptian, the Hawar Member (equivalent) is earliest Aptian in age. The paleo-environments recorded range from the tidal mudflat to the argillaceous platform setting (outer ramp) below the storm wave base. In terms of sequence stratigraphy, four large-scale transgressive-regressive cycles of Cretaceous age (Jurf and Qishn formations) were distinguished. Sequence I, a dolomitized succession termed Jurf Formation, is the equivalent of the Lekhwair, the Lower Kharaib and possibly older Cretaceous units. -
Mid-Cretaceous Step-Wise Demise of the Carbonate Platform Biota in The

All available records of this biota in the Northwest Pacific (Japan and Sakhalin Island) are summarized in order to elucidate its stratigraphic distribution patterns and faunal changes, with special attention given to the biota of the Late Aptian–Early Albian. This carbonate platform biota flourished from the Berriasian to Early Albian interval in the Northwest Pacific, indicating that the Northwest Pacific clearly belonged to the Tethyan biotic realm at that time. A step-wise demise of the carbonate platform biota transpired in the latest Aptian to middle Albian interval. Mesogean key taxa (rudists and dasycladacean algae), some Mesogean indicators (hermatypic corals and stromatoporoids) and nerineacean gastropods disappeared at the Late Aptian to Early Albian transition. Following this event, other Mesogean indicators (orbitolinid foraminifers and calcareous red algae) and coated grains disappeared at the Early to middle Albian transition. There is no record of carbonate platform biota in the Northwest Pacific during the long interval between the Middle Albian and Paleocene. -
Problems in the Identity of "Crioceras" Barremense KILIAN, 1895 (Ancyloceratida, Late Barremian), and Their Proposed Resolution
Carnets de Géologie / Notebooks on Geology - Article 2010/01 (CG2010_A01) Problems in the identity of "Crioceras" barremense KILIAN, 1895 (Ancyloceratida, Late Barremian), and their proposed resolution 1 Didier BERT * 2 Robert BUSNARDO 3 Gérard DELANOY 4 Stéphane BERSAC Abstract: The study of "Crioceras" barremense KILIAN was undertaken as a part of the revision of the Hemihoplitidae. This species was considered "classic" and has been used as the index of an Upper Barremian subzone; this usage raises a number of problems. The type specimen from Tyrol was a fragment described and illustrated by UHLIG as Crioceras sp. ind. aff. roemeri. This specimen could not be retrieved, and a topotype could not be collected. Our study revealed that there is both a biostratigraphic hiatus and important differences between conceptions of this species: (1) that ascribed UHLIG's type specimen (Upper Barremian, Tyrol), (2) KILIAN's concept of the specimen he found and named "Crioceras" barremense (probably a Camereiceras from the uppermost levels of the Vandenheckei Subzone or from the basal Sartousiana subzone of the Nauvin site, southeastern France) and (3) current interpretations of authors, who often synonymize the type specimen with Gassendiceras alpinum (d'ORBIGNY), which occurs in the middle of the Vandenheckei Subzone. So there is a real confusion concerning the synonymy of "Crioceras" barremense. The age of UHLIG's type specimen is too imprecise and its preservation too fragmentary to be reliably identifiable, because the same morphology and ornamentation exist in several species of other genera. Therefore, we recommend the use of the species "Crioceras" barremense KILIAN be avoided, in particular as an index, along with that of the genus Barrancyloceras VERMEULEN for which "C." barremense is used as reference. -
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. -

CLENCH CURATOR OF MOW.USKS, HARVARD UNIVERSITY INTRODUCTION The following report is based largely upon the extensive collection of Pacific island mollusks in Bernice P. Bishop Museum. The study was made possible by a Yale-Bishop Museum Fellowship which was granted for the winter of 1940-1941. Upon my return to Cambridge, the collection of mollusks in my charge was reviewed for additional data for the two families considered in this paper. I am exceedingly grateful to the Yale University Committee and to the Trustees of Bishop Museum for this fellowship and for the rare opportunity to study in the Hawaiian Islands. The value to the individual scientist of an opportunity of this sort far transcends the published results of a single report. Such an experience with the chance of seeing new and different animals and plants in the field and under totally different conditions naturally tends to shift preconceived viewpoints obtained from other field experience. -

THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject. -
