The meeting was hosted by the Department of Geology, Lund University, in June 9–19 2013 and followed the successful annual meetings held in Madrid/Ludlow (2011) and Cincinnati (2012). The Lund conference was arranged jointly with the annual meetings of the Cambrian, Ordovician and Silurian subcommissions on stratigraphy, and included a post-conference excursion to key geological localities in Skåne, Västergötland and the Oslo Region. The conference was a focus for cutting-edge research in Lower and Middle Palaeozoic geology and palaeontology, and the presentations covered a wide range of topics from morphology and taxonomy of various fossil groups through advances in geochemistry and stratigraphy to biogeography, palaeoecology and palaeoclimatology. We would like to express our sincere gratitude to Anders Lindskog and Kristina Mehlqvist for their meticulous editing of the meeting proceedings. We are also grateful for valuable input from the organization and scientific committee associated with the meeting. We acknowledge financial support from the Swedish Research Council (grant D0013001 to MC), the Geological Survey of Sweden, the Geological Society of Sweden, the Department of Geology at Lund University, and the municipality of Lund.

  • A Probable Case of Heterochrony in the Solutan
    A probable case of heterochrony in the solutan Dendrocystites Barrande, 1887 (Echinodermata: Blastozoa) from the Upper Ordovician of the Prague Basin (Czech Republic) and a revision of the family Dendrocystitidae Bassler, 1938 FLEUR NOAILLES, BERTRAND LEFEBVRE & LIBOR KAIÈKA The morphology of the Late Ordovician solutan Dendrocystites is reevaluated based on more than 300 specimens from the Letná and Zahořany formations (Prague Basin, Czech Republic). This genus is reported for the first time from the Bohdalec Formation, and its presence is confirmed in the Vinice Formation. The morphology of all specimens of the stratigraphically older species D. barrandei (Sandbian) is identical to that of small to medium-size individuals of D. sedgwicki (Katian). Distinctive characters of D. sedgwicki occur only in the largest specimens, and are all size-related (more asymmetrical thecal outlines, stronger ornamentation, rosetting pattern of thecal plates, proliferation of platelets in the proxistele). Consequently, the transition from D. barrandei to D. sedgwicki is interpreted as the result of heterochronic processes, with the largest individuals of D. sedgwicki displaying hyperadult morphologies (hyper- morphosis). Dendrocystites is locally abundant in both the Letná and Zahořany formations, but extremely rare in the deeper deposits of the Vinice and Bohdalec formations. This pattern coincides closely with first order fluctuations of the sea-level in the Prague Basin. The life orientation and implied feeding strategy of Dendrocystites and other solutans are both critically discussed. Several independent lines of evidence suggest that solutans were more likely detritus-feeders. Finally, it is proposed that two morphologically distinct patterns of dististele organization were elaborated independently from the polyplated, undifferentiated stalk-like appendage of Coleicarpus (plesiomorphic condition).

  • Proceedings of the Indiana Academy of Science 1919, 35:261-340
    Notes on the History of the Paleontological Collection, Department of Geology, Indiana University Alan Stanley Horowitz Department of Geology, Indiana University Bloomington, Indiana 47405 Introduction In the past, paleontologic papers, especially those printed prior to 1930, com- monly did not indicate the repository of the collections on which the published record was based. Workers generally assume the collections reside at the institution to which the author was associated as either student or faculty. Some early workers were not associated with any academic institution, and early collections have been scattered or destroyed. Because inquiries are made frequently to Indiana University concerning both the University and Indiana State Geological Survey collections, this paper provides some general information on earlier collections insofar as is presently known. According to Wylie (36), the records of Indiana University prior to 1883 were largely destroyed by fire. Wylie (36:31) quoted statements concerning geological col- lections from as early as 1852 in legislative acts affecting the University, e.g., "The Lecturers were also to make geological examinations, and collect mineralogical specimens for the cabinet by volunteer donations." No attempt has been made to reconstruct possible paleontological collections, other than the Owen collection, based on any ex- tant University catalogues or Reports of the President of Indiana University published prior to 1883, and I assume that any geological collections or catalogues prior to this date were lost in the 1883 fire reported by Wylie (36:83). The Owen Collection Our knowledge of the Indiana University Department of Geology (IUB) paleon- tological collections begins with the collection of David Dale Owen.

The effect of this transition on the ecology and Attachment evolution of benthic metazoans is termed the Cambrian Substrate Revolution (CSR), and this is thought to have impacted greatly on early suspension-feeding echinoderms in particular. According to this paradigm, most echinoderms rested directly on non-bioturbated soft substrates as sediment attachers and stickers during the Cambrian Epoch 2. As the substrates became increasingly disturbed by burrowing, forming a progressively thickening mixed layer, echinoderms developed new strategies for attaching to firm and hard substrates.

Although we will concentrate on the principal objectives of the trip, we will have the opportunity to observe many features of the structure, geomorpnology, and Cenozoic history of the region as well. Travel will be by bus from San Francisco to Bishop, California on Thursday, November 17. For this segment of the trip, and the re- turn to San Francisco from Bishop, no guidebook has been prepared. We are fortunate, however, to have Mr. Bennie Troxel of the Cali- fornia Division of Mines and Geology with us.. Together we will try to provide you with some of the highlights of the trans-Sierran route. Field gear, including sturdy shoes and warm clothing is essential. Stops at the higher elevations are likely to be cold ones. As is true of all too many field trips, especially those using bus transportation, many of the best localities for collecting Cambrian fossils and for viewing features of the Precambrian and Cambrian succession are in areas too remote or too inaccessible to be visited.

  • (Silurian) Conodont Biostratigraphy of Saaremaa, Estonia, and a Correlation with Britain
    Journal of’ Micropalaeontology, 17: 33-50. 0262-821)</98 $10.00 0 1998 British Micropalaeontological Society. Upper Wenlock to Lower Piidoli (Silurian) conodont biostratigraphy of Saaremaa, Estonia, and a correlation with Britain VIIVE VIIRA’ & RICHARD J. ALDRIDGE’ ’ Institute of Geology, Estonia Avenue 7, EE0105 Tallinn, Estonia. Department of Geology, University of Leicester, Leicester LEI 7RH, UK ABSTRACT - The closely related conodonts Ozarkodina bohemica, 0. snajdri and 0. crispa form a clade that provides useful biostratigraphical indices through the upper Silurian. Collections from boreholes and surface outcrops on Saaremaa and from a borehole at Kolka, Latvia, contain new morphotypes of 0. bohemica and 0.crispa. A new subspecies, 0. snajdriparasnajdri, is also distinguished, occurring above 0. crispa in the Kuressaare and lowermost Kaugatuma stages. Evidence from conodonts and other fossils; primarily chitinozoans, ostracods and ichthyoliths, can be used to correlate the upper Silurian succession of Saaremaa with those of the Welsh Borderland and Gotland, although some problems remain to be solved. The microfossil distribution suggests that there may be a major break at the base of the Ludlow Bone Bed Member at Ludlow, equivalent to the Kuressaare Formation on Saaremaa. J.

Bui Duc Thang, Department of Palaeontoogy, Institute of Geology and Mineral Resources Thanh Xuan, Hanot. Received: December, 1987. INTRODUCTION This paper is the first report on Triassic conodonts from Vietnam. The conodonts were found in a section exposed near the railway station Bac Thuy (fig. 1) in the province of Lang Son in the northeastern part of Vietnam. The rocks exposed there belong to the Suoi Bang Formation (fig. 2), the lower part of which consists of sandstones, mudstones, and clays, while intercalations of marine carbonate sediments (dolomitic sand- stones and limestones) appear towards the upper part (Vu Khuc 1980). Thirteen samples (about 1 kilogram each sample) have been collected in the section (fig. 3). Only five samples from the highest part of the section yielded conodonts (fig. 3, table I), on average 150-200 specimens per sample. Three hundred sixty specimens were suitablye for determina- tion. Samples with abundant conodonts included also fish scales and teeth, small ammonite shells, and foraminifera.

  • Middle Cambrian Gogiid Echinoderms from Northeast Spain: Taxonomy, Palaeoecology, and Palaeogeographic Implications
    Middle Cambrian gogiid echinoderms from Northeast Spain: Taxonomy, palaeoecology, and palaeogeographic implications SAMUEL ZAMORA, RODOLFO GOZALO, and ELADIO LIÑÁN Zamora, S., Gozalo, R., and Liñán, E. 2009. Middle Cambrian gogiid echinoderms from Northeast Spain: Taxonomy, palaeo− ecology, and palaeogeographic implications. Acta Palaeontologica Polonica 54 (2): 253–265. DOI: 10.4202/app.2008.0010 Gogia parsleyi Zamora sp. nov. and Gogia sp. are described from two different echinoderm assemblages, both from the middle Cambrian of the Murero Formation (Iberian Chains, NE Spain). Gogia parsleyi is reconstructed and described on the basis of fifteen complete or partial specimens and numerous isolated plates. It is characterised by spiralled brachioles, simple epispires, sometimes covered by stereomic domes or tiny cover plates, and by thecal plates arranged in subregular circlets. This gogiid population comprises juveniles, advanced juveniles and mature individuals. The material was found in the upper part of the Murero Formation (upper Caesaraugustian–lower Languedocian). Gogia sp. is represented by two almost complete specimens and several isolated plates from the lower part of the Murero Formation (lower Caesar− augustian). The genus Gogia was first described in Western Gondwana from the Languedocian (upper middle Cambrian) of France, but the material from Spain is older and represents the oldest record of this genus in Gondwana, suggesting an early migration from Laurentia. The gogiids are well preserved in two echinoderm Lagerstätten, which, together with other echinoderms, comprise the majority of the fossil fauna. Both levels are derived from obrution deposits produced in calm and open marine conditions, sometimes affected by sporadic storms. Their holdfast morphology suggests that these gogiids were low−tier suspension feeders, living attached to trilobite fragments in a soft, muddy environment.
