  • Paleoecology of the Greater Phyllopod Bed Community, Burgess Shale ⁎ Jean-Bernard Caron , Donald A
    Available online at www.sciencedirect.com Palaeogeography, Palaeoclimatology, Palaeoecology 258 (2008) 222–256 www.elsevier.com/locate/palaeo Paleoecology of the Greater Phyllopod Bed community, Burgess Shale ⁎ Jean-Bernard Caron , Donald A. Jackson Department of Ecology and Evolutionary Biology, University of Toronto, Toronto, Ontario, Canada M5S 3G5 Accepted 3 May 2007 Abstract To better understand temporal variations in species diversity and composition, ecological attributes, and environmental influences for the Middle Cambrian Burgess Shale community, we studied 50,900 fossil specimens belonging to 158 genera (mostly monospecific and non-biomineralized) representing 17 major taxonomic groups and 17 ecological categories. Fossils were collected in situ from within 26 massive siliciclastic mudstone beds of the Greater Phyllopod Bed (Walcott Quarry — Fossil Ridge). Previous taphonomic studies have demonstrated that each bed represents a single obrution event capturing a predominantly benthic community represented by census- and time-averaged assemblages, preserved within habitat. The Greater Phyllopod Bed (GPB) corresponds to an estimated depositional interval of 10 to 100 KA and thus potentially preserves community patterns in ecological and short-term evolutionary time. The community is dominated by epibenthic vagile deposit feeders and sessile suspension feeders, represented primarily by arthropods and sponges. Most species are characterized by low abundance and short stratigraphic range and usually do not recur through the section. It is likely that these are stenotopic forms (i.e., tolerant of a narrow range of habitats, or having a narrow geographical distribution). The few recurrent species tend to be numerically abundant and may represent eurytopic organisms (i.e., tolerant of a wide range of habitats, or having a wide geographical distribution).

Su estudio, que ha sido fuente de controversias desde el s. XIX, suscita en la actualidad una intensa investigación y no poca polémica. En este trabajo se describen algunas biotas que antecedieron a la explosión cámbrica, se describe ésta y se discuten las posibles causas de este acontecimiento.

  • In Search of Vanished Ages--Field Trips to Fossil Localities in California, Nevada, and Utah
    i In Search Of Vanished Ages Field trips to fossil localities in California, Nevada, and Utah By Inyo A view across the middle Miocene Barstow Formation on California’s Mojave Desert. Here, limestone concretions that occur in rocks deposited in a freshwater lake system approximately 17 million year-ago produce exquisitely preserved, fully three-dimensional insects, spiders, water mites, and fairy shrimp that can be dissolved free of their stone encasings with a diluted acid solution—one of only a handful of localities worldwide where fossil insects can be removed successfully from their matrixes without obliterating the specimens. ii Table of Contents Chapter Page 1—Fossil Plants At Aldrich Hill 1 2—A Visit To Ammonite Canyon, Nevada 6 3—Fossil Insects And Vertebrates On The Mojave Desert, California 15 4—Fossil Plants At Buffalo Canyon, Nevada 45 5--Ordovician Fossils At The Great Beatty Mudmound, Nevada 50 6--Fossil Plants And Insects At Bull Run, Nevada 58 7-- Field Trip To The Copper Basin Fossil Flora, Nevada 65 8--Trilobites In The Nopah Range, Inyo County, California 70 9--Field Trip To A Vertebrate Fossil Locality In The Coso Range, California 76 10--Plant Fossils In The Dead Camel Range, Nevada 83 11-- A Visit To The Early Cambrian Waucoba Spring Geologic Section, California 88 12-- Fossils In Millard County, Utah 95 13--A Visit To Fossil Valley, Great Basin Desert, Nevada 107 14--High Inyo Mountains Fossils, California 119 15--Early Cambrian Fossils In Western Nevada 126 16--Field Trip To The Kettleman Hills Fossil District,

This special meeting commemorates the centenary of the discovery of the Burgess Shale by Charles D. Walcott. We are delighted to welcome a broad spectrum of over 135 Cambrian Explosion workers from across the globe, attending this conference to exchange ideas on current research and to visit the famous localities, part of the Canadian Mountain Parks World Heritage Site. This abstract volume is a compilation of the abstracts for keynote, oral and poster presentations. The suite of abstracts received is a testament to the quality and diversity of current research in this field, one hundred years after the discovery of the first Burgess Shale animals.

    Cambrian Earth History The Paleozoic Era Cambrian Plate Tectonics The Cambrian “Explosion” The Burgess Shale The Chengjiang Fauna hp://www.cyberpiggy.com/ Copyright Greg Carter The Paleozoic The Paleozoic is the earliest, and longest, era of the Phanerozoic Eon. The Cambrian is the earliest period of the Paleozoic. All animal phyla with good fossil records (including chordates) first appear during the early Paleozoic, with almost all appearing during the Cambrian. Only one such animal phylum appears aer the Cambrian (bryozoans appear in the Ordovician). The end of the Paleozoic is punctuated by the largest mass exFncFon in Earth’s long history.

Geyer, 1997 Cambrian Plate Tectonics The Cambrian was a relatively quiet time for Laurentia, which drifted north toward the equator. The Avalon Island Arc, Baltica and Siberia were closing in on Laurentia, but wouldn’t arrive until later in the Paleozoic. The Carolina Terrane was forming well to the south, near the part of Gondwana that would eventually become Namibia. http://jan.ucc.nau.edu/~rcb7/510NAt.jpg hp://www.uky.edu/KGS/educaBon/images/ca_explo.gif The Cambrian Explosion animals without animals with skeletons skeletons “Sudden” appearance in the fossil record and rapid diversification of animals with hard parts http://www.palaeos.com/Paleozoic/Cambrian/Cambrian.htm The Cambrian “Explosion” in Animal Diversity Global Changes Why???
