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.

  • Glossary Glossary
    Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts.

  • Shell Microstructures in Early Cambrian Molluscs
    Shell microstructures in Early Cambrian molluscs ARTEM KOUCHINSKY Kouchinsky, A. 2000. Shell microstructures in Early Cambrian molluscs. - Acta Palaeontologica Polonica 45,2, 119-150. The affinities of a considerable part of the earliest skeletal fossils are problematical, but investigation of their microstructures may be useful for understanding biomineralization mechanisms in early metazoans and helpful for their taxonomy. The skeletons of Early Cambrian mollusc-like organisms increased by marginal secretion of new growth lamel- lae or sclerites, the recognized basal elements of which were fibers of apparently aragon- ite. The juvenile part of some composite shells consisted of needle-like sclerites; the adult part was built of hollow leaf-like sclerites. A layer of mineralized prism-like units (low aragonitic prisms or flattened spherulites) surrounded by an organic matrix possibly existed in most of the shells with continuous walls. The distribution of initial points of the prism-like units on a periostracurn-like sheet and their growth rate were mostly regular. The units may be replicated on the surface of internal molds as shallow concave poly- gons, which may contain a more or less well-expressed tubercle in their center. Tubercles are often not enclosed in concave polygons and may co-occur with other types of tex- tures. Convex polygons seem to have resulted from decalcification of prism-like units. They do not co-occur with tubercles. The latter are interpreted as casts of pore channels in the wall possibly playing a role in biomineralization or pits serving as attachment sites of groups of mantle cells. Casts of fibers and/or lamellar units may overlap a polygonal tex- ture or occur without it.

Brisbane. ISSN0079-8835. Aconsolidated list of available generic names introduced since the beginning of the binomial nomenclature system for trilobites is presented for the first time. Each entry is accompanied by the author and date of availability, by the name of the type species, by a lithostratigraphic or biostratigraphic and geographic reference for the type species, by a family assignment and by an age indication of the type species at the Period level (e.g. MCAM, LDEV). A second listing of these names is taxonomically arranged in families with the families listed alphabetically, higher level classification being outside the scope of this work.

Risiede a Cancun, Messico, dove si dedica ad attività legate all'ambiente marino. All'età di 16 anni, ha iniziato una lunga collaborazione con il Museo di Storia Naturale di Milano, ed è a partire dal 1970 che prese inizio la vera passione per i trilobiti, dando avvio a quella che oggi è diventata una delle collezioni paleontologiche più importanti al mondo. La sua instancabile attività di ricerca sul terreno in varie parti del globo e la collaborazione con professionisti del settore, ha permesso la descrizione di nuove specie di trilobiti ed artropodi.

    2nd International Trilobite Conference (Brock University, St. Catharines, Ontario, August 22-24, 1997) ABSTRACTS. Characters and Parsimony. Jonathan M. Adrain, Department of Palaeontology, The Natural History Museum, London SW7 5BD, United King- dom; Gregory D. Edgecombe, Centre for Evolutionary Research, Australian Museum, 6 College Street, Sydney South, New South Wales 2000, Australia Character analysis is the single most important element of any phylogenetic study. Characters are simply criteria for comparing homologous organismic parts between taxa. Homology of organismic parts in any phylogenetic study is an a priori assumption, founded upon topological similarity through some or all stages of ontogeny. Once homolo- gies have been suggested, characters are invented by specifying bases of comparison of organismic parts from taxon to taxon within the study group. Ideally, all variation in a single homology occurring within the study group should be accounted for. Comparisons are between attributes of homologous parts, (e.g., simple presence, size of some- thing, number of something), and these attributes are referred to as character states. Study taxa are assigned member- ship in one (or more, in the case of polymorphisms) character-state for each character in the analysis. A single char- acter now implies discrete groupings of taxa, but this in itself does not constitute a phylogeny. In order to suggest or convey phylogenetic information, the historical status of each character-state, and of the the group of taxa it sug- gests, must be evaluated. That is, in the case of any two states belonging to the same character, we need to discover whether one state is primitive (broadly speaking, ancestral) or derived (representative of an evolutionary innovation) relative to the other.
