SCHWEITZER Research Associate, Section of Invertebrate Paleontology; Department of Geology, Kent State University Stark Campus, Canton, OH 44720 ([email protected]) ABSTRACT Five previously undescribed decapod taxa have been collected from lower upper Miocene rocks of the Puerto Madryn Formation, Peninsula Valdes region, Chubut Province, Patagonia, Argentina. New species include Osachila valdesensis, Rochinia boschii, Romaleon parspinosus, Panopeus piramidensis, and Ocypode vericoncava. Chaceon peruvianus and Proterocarcinus latus are also reported from the unit, in addition to two indeterminate xanthoid species. Assignment of fossil taxa to genera within the Panopeidae Ortmann, 1893, is difficult due to the marked similarity in dorsal carapace characters among several genera. Panopeus whittenensis Glaessner, 1980, is herein referred to Pakicarcinus Schweitzer et al., 2004. The Puerto Madryn Formation exposed near Puerto Piramide contains three distinct Facies Associations (1-3), each associated with specific paleoecological and paleoenvironmental conditions, and which recur throughout the section and represent trangressive systems tract (TST) deposits and highstand systems tract (HST) deposits. Within Facies Association 1, near the base of the section at Puerto Piramide, three paleosurfaces containing invertebrate fossils in life position are exposed and have been carefully mapped in plan view. -

Ordovician (Billingen and Volkhov Stages) Brachiopod Faunas of the East Baltic
Eva Egerquist Ordovician (Billingen and Volkhov stages) brachiopod faunas of the East Baltic 1 Dissertation presented at Uppsala University to be publicly examined in Lecture Theatre, Palaeontology building, Uppsala, Friday, June 4, 2004 at 13.00 for the degree of Doctor of Philosophy. The examination will be conducted in English. Abstract Egerquist E. 2004. Ordovician (Billingen and Volkhov stages) brachiopod faunas of the East Baltic. 34 pp. Uppsala. ISBN 91-506-1756-7 Lower-Middle Ordovician (Arenig) successions in the East Baltic have been investigated for more than one hundred and fifty years. Nevertheless detailed sampling still yields new species and better knowledge of the environment in which these organisms lived. The successions are well suited for bed by bed sampling because of the lack of tectonic disturbance and because the sequences are well documented. This study analyses collections of Billingen-Volkhov age mainly from the St. Petersburg region, but also from Estonia. A great deal of the material was obtained from the marly to clayey, soft sediment that intercalates the compact packstones and wackestones in the succession. Twenty-nine of these clay horizons were used for diversity estimates on the fauna through the succession. The most thoroughly investigated groups for this investigation were rhynchonelliformean brachiopods, conodonts and ostracodes. The results indicate that variances in diversity and abundance levels for these groups were not correlated, either to each other or to the small-scale sea level fluctuations that have been suggested for the region. However, diversity dynamics of brachiopods and ostracodes confirm the large-scale upward shallowing of the basin into the Upper Volkhov. -

Abstract The early Silurian reefs of the Attawapiskat Formation in the Hudson Bay Basin preserved the oldest record of major invasion of the coral-stromatoporoid skeletal reefs by brachiopods and other marine shelly benthos, providing an excellent opportunity for studying the early evolution, functional morphology, and community organization of the rich and diverse reef-dwelling brachiopods. Biometric and multivariate analysis demonstrate that the reef-dwelling Pentameroides septentrionalis evolved from the level- bottom-dwelling Pentameroides subrectus to develop a larger and more globular shell. -

Darragh* and George W. Kendriek** ABSTRACT One scaphopod and 35 gastropod species are recorded from the Late Maastrichtian Miria Formation of the Carnarvon Basin, northwestern Australia. Preservation of the fossils suggests that the assemblage, which is inferred to contain herbivores, possible detrital feeders, graz.ers, predatory and ectoparasitic carnivores, is only partly representative of the original fauna. The original mineralogy of the shells has, in part, determined which mollusks have been preserved, their state at recovery, and whether or not they can be identified. Primary calcite has remained but argonite has been lost and partially replaced by secondary calcite. Six species are known only from internal moulds, Five new species - Conotomaria millacis sp. nov., Conolomaria (7) cypsela sp. nov., Leptomaria perallcisa sp. -
Relict Ordovician Brachiopod Faunas in the Lower Silurian of Asker, Oslo Region, Norway

The diverse brachiopod fauna of the lowest part of the Solvik Forrnation (Lower Llandovery) in the Asker area of the Oslo Region is a well- organised association overwhelmingly dominated by relict genera more typical of the Ordovician. These taxa appear to have survived the extinction events of the late Ordovician in deep water facies in or adjacent to the central Oslo Region. The gradual disap pearance of Ordovician elements through the sequence is considered to have resulted from un successful competition with immigrant stocks of Silurian aspect that may have originated around the shelves of archipelagos created during the late Ordovician regression. Thus competition is suggested to account for the final pulse of fauna) extinction above the Ordovician-Silurian boundary. B. G.

(2003): Silicified brachiopods of the Kotýs Limestone (Lochkovian) in the Bubovice area (Barrandian, Bohemia). – Acta Mus. Nat. Pragae, Ser. B, Hist. Nat., 59 (3–4): 99–150. Praha. ISSN 0036-5343 Abstract: An exceptionally preserved silicified brachiopod material is described from the Kotýs Limestone (Lochkov Forma- tion, Lochkovian) from two localities between Bubovice and Loděnice in the Central Bohemia. The shells have preserved the finest details of internal and external morphology, such as brachidia, crural plates, trails and spines, and represent the unique brachiopod material in the Barrandian. In total thirty-eight species have been determined, with new species Dicoelosia prae- dimera, Muriferella pishulinae, Spinatrypina variabilis, Glassina gutta, Retzia piriformis, Ambocoelia bubovica, and Quad- rithyris subrobusta. Genera Muriferella, Anastrophia, Spinatrypina, Glassina, Retzia, and Quadrithyris have been recognized from the Lochkovian strata for the first time in the Barrandian. The composition of the brachiopod fauna in the studied sequ- ence indicates a transition from a shallower, high-diversity assemblage with spiriferids, pentamerids, strophomenids, orthote- tids, large orthids and spinose atrypids to a deeper, low-diversity assemblage with dominance of small orthids, and costellate and smooth atrypids.

Sponge Contributions to the Geology and Biology of Reefs: Past, Present, and Future 5
Sponge Contributions to the Geology and Biology of Reefs: Past, Present, and Future 5 Janie Wulff Abstract Histories of sponges and reefs have been intertwined from the beginning. Paleozoic and Mesozoic sponges generated solid building blocks, and constructed reefs in collaboration with microbes and other encrusting organisms. During the Cenozoic, sponges on reefs have assumed various accessory geological roles, including adhering living corals to the reef frame, protecting solid biogenic carbonate from bioeroders, generating sediment and weakening corals by eroding solid substrate, and consolidating loose rubble to facilitate coral recruitment and reef recovery after physical disturbance. These many influences of sponges on substratum stability, and on coral survival and recruitment, blur distinctions between geological vs. biological roles. Biological roles of sponges on modern reefs include highly efficient filtering of bacteria- sized plankton from the water column, harboring of hundreds of species of animal and plant symbionts, influencing seawater chemistry in conjunction with their diverse microbial symbionts, and serving as food for charismatic megafauna. Sponges may have been playing these roles for hundreds of millions of years, but the meager fossil record of soft-bodied sponges impedes historical analysis. Sponges are masters of intrigue. They play roles that cannot be observed directly and then vanish without a trace, thereby thwarting understanding of their roles in the absence of carefully controlled manipulative experiments and time-series observations. Sponges are more heterogeneous than corals in their ecological requirements and vulnerabilities. Seri- ous misinterpretations have resulted from over-generalizing from a few conspicuous species to the thousands of coral-reef sponge species, representing over twenty orders in three classes, and a great variety of body plans and relationships to corals and solid carbonate substrata.
