ISSN 0068-1016 Distributed July 30, 1976 Price $5.00 (Subject to change without notice) 4-77 400 26481 EDITORIAL PREFACE Prior to the last decade, the large majority of Cambrian studies in west- ern North America were concerned with either stratigraphy or systematics of trilobites. A new phase of Cambrian investigations commenced about a decade ago with expanded interest in not only stratigraphy and trilobites, but many other types of organisms, depositional environments, facies rela- tionships, paleoecology, evolution, and other topics. Of particular significance is a marked increase in cooperation between paleontologists and sedimentolo- gists to better present an integrated analysis of Cambrian faunas and their environments. Because favorable cllmate and structure interact to provide ex- cellent outcrops in numerous mountain ranges, much of this new work has been concentrated in the Great Basin of eastern and southern Nevada, western Utah, and parts of adjacent California and Idaho. The idea of a symposium to summarize thls new Cambrian work was first discussed by A. R. Palmer, R. A. Robison, and M. E. Taylor during 1972 and resulted in a Paleontological Society symposium that was convened in Salt Lake City, Utah, on October 20, 1975. Limits of a one-day session allowed for presentations by probably less than half of those qualified to participate. However, the program is judged to be representative of the problems being investigated and the results being obtained. This volume contains 14 of the 22 papers read at the symposium. Some of the papers that were read are being published elsewhere. For a variety of other reasons, some of the symposium partrcipants were unable to contribute to this volume. The reader is referred to volume 7, number 7, of the 1975 Geological Society of America Abstracts with Programs for a complete list of symposium topics (p. 922-923) and abstracts. One short paper, "Trilobites in Utah Folklore," although not read at the syrnposlum, has been added here be- cause it concerns Elrathza kingii, which is probably the most widely known of all Cambrian fossils. The diversity of subject matter covered in the total of 15 papers is obvious, and it is hoped that from the seemingly autonomous approaches, the reader will gain a general feeling of the new era of Cambrian investigation. Several of the papers in this volume are concerned with areas in western Utah that are covered by a series of excellent geologic maps and stratigraphic columns that have been prepared by L. F. Hintze. Readers may well benefit by reference to these 15-minute quadrangle maps, which were published in 1974 as U. S. Geological Survey Miscellaneous Field Stud~esMaps MI;-633 to 637. Professor Hintze has additional maps in preparation. We acknowledge with gratitude the aid of J. K. Rigby and W. K. Hamb- lin in arranging for publication of these syn~posiumpapers. Funds for much of the miscellaneous cost of organizing thrs volume were provided by the Department of Geology, University of Kansas. Flnally, we appreciate the cordial and prompt cooperation we received, without exception, from each of the contributors. Lawrence, Kansas R. A. Robison March 1976 A J.

ROBISONZ 'U.S. Geological Survey, Wa.shing;on, D.C. 20244 'University oof Kansas, Lawrence 66045 INTRODUCTION Well-preserved specimens of Elrathia kijzgii (Meek) are found in the Wheeler Formation of Middle Cambrian age east of Antelope Spring in the Wheeler Amphitheater, House Range, Millard County, Utah (Text-fig. 1 ) . The species is common in western Utah (Robison, 1964), but the locality at Antelope Spring is unique in yielding articulated, dark-colored dorsal exo- skeletons having thick deposits of fibrous calcite on the under surfaces (Bright, 1959). The secondary calcite strengthens the fossil so that specimens weather free or are easily extricated from the rock matrix. Great abundance, fine degree of preservation, and ease of removing speci- mens from the matrix have resulted in Elrathia kingii becoming popular among both professional and amateur fossil collectors. Photographs of Elrathia kingii from the Wheeler Amphitheater have been widely published in textbooks, and commercial demands are currently sufficient to support a small private quarry- ing operation. The trilobite is popular among rockhounds, a situation un- doubtedly stimulated by several popular articles on fossil collecting at the Wheeler Amphitheater (for example, Beckwith, 1931; Robison, 1970; Dicker- son and Dickerson, 1972). Some historical records suggest that Elrathia kilzgii was collected at the Wheeler Amphitheater and fabricated Into amulets by the Pahvant Ute Indians from Sevier Valley, Utah. The story provides an Interesting sidelight to studies of Cambrian trilobites from the Great Basin. BECKWITH'S NECKLACE Frank Asahel Beckwith lived in Delta, Utah, from 1913 until his death in 1951. Mr. Beckwith, a banker, later the editor of the Millard County Chronicle, spent much of his free time roaming the desert regions of western Utah study- ing the geology and history of the local Indians-the Pahvant Utes. Despite a lack of college training, he *was an accon~plishednatural historian. Beckwith was familiar with the more common local fossils, having served as guide for Charles E. Resser, Teiichi Kobayashi, Riuji Endo, and other geologists who occasionally visited western Utah on collecting trips. Out of respect for Beckwith's prowess as a fossil collector, Charles E. Resser, Smith- sonian Institution, named the Middle Cambrian merostome Beckzuithia typa after him in 1931. Upon his death, Beckwith left a substantial personal library, a large col- lection of fossils, Indian artifacts, photographs, and voluminous notes on ob- servations made during his travels. The narrative that follows is based largely upon information from an

  • On the Continuity of Background and Mass Extinction
    Paleobiology, 29(4), 2003, pp. 455±467 On the continuity of background and mass extinction Steve C. Wang Abstract.ÐDo mass extinctions grade continuously into the background extinctions occurring throughout the history of life, or are they a fundamentally distinct phenomenon that cannot be explained by processes responsible for background extinction? Various criteria have been proposed for addressing this question, including approaches based on physical mechanisms, ecological se- lectivity, and statistical characterizations of extinction intensities. Here I propose a framework de®ning three types of continuity of mass and background extinc- tionsÐcontinuity of cause, continuity of effect, and continuity of magnitude. I test the third type of continuity with a statistical method based on kernel density estimation. Previous statistical ap- proaches typically have examined quantitative characteristics of mass extinctions (such as metrics of extinction intensity) and compared them with the distribution of such characteristics associated with background extinctions. If mass extinctions are outliers, or are separated by a gap from back- ground extinctions, the distinctness of mass extinctions is supported. In this paper I apply Silverman's Critical Bandwidth Test to test for the continuity of mass ex- tinctions by applying kernel density estimation and bootstrap modality testing. The method im- proves on existing work based on searching for gaps in histograms, in that it does not depend on arbitrary choices of parameters (such as bin widths for histograms), and provides a direct estimate of the signi®cance of continuities or gaps in observed extinction intensities. I am thus able to test rigorously whether differences between mass extinctions and background extinctions are statisti- cally signi®cant.

This study presents a re-evaluation of the arthropod ichnotaxa of the Cruziana rugosa Group from bio- and/or lithostratigraphically well-defined Lower to Upper Ordovician siliciclastic sections of southern and central Bolivia. With the exception of Cruziana rouaulti, the ichnofaunas contain all the members of the Cruziana rugosa Group throughout the Ordovician (Arenig to Caradoc) successions in Bolivia. The Bolivian material therefore indicates that these arthropod ichnofossil assemblages are suitable for recognizing Ordovician strata in Bolivia. These findings cast doubt on their use as reliable indicators for a global intra-Ordovician (Arenig to Caradoc) biozonation of Peri-Gondwanan sedimentary successions.

    Trilobites of the Hagastrand Member (Tøyen Formation, lowermost Arenig) from the Oslo Region, Norway. Part Il: Remaining non-asaphid groups OLE A. HOEL Hoel, O. A.: Trilobites of the Hagastrand Member (Tøyen Formation, lowermost Arenig) from the Oslo Region, Norway. Part Il: remaining non-asaphid groups. Norsk Geologisk Tidsskrift, Vol. 79, pp. 259-280. Oslo 1999. ISSN 0029-196X. This is Part Il of a two-part description of the trilobite fauna of the Hagastrand Member (Tøyen Formation) in the Oslo, Eiker­ Sandsvær, Modum and Mjøsa areas. In this part, the non-asaphid trilobites are described, while the asaphid species have been described previously. The history and status of the Tremadoc-Arenig Boundary problem is also reviewed, and I have found no reason to insert a Hunnebergian Series between the Tremadoc and the Arenig series, as has been suggested by some workers. Descriptions of the localities yielding this special trilobite fauna are provided. Most of the 22 trilobite species found in the Hagastrand Member also occur in Sweden. The 12 non-asaphid trilobites described herein belong to the families Metagnostidae, Shumardiidae, Remopleurididae, Nileidae, Cyclopygidae, Raphiophoridae, Alsataspididae and Pliomeridae. One new species is described; Robergiella tjemviki n. sp. Ole A. Hoel, Paleontologisk Museum, Sars gate l, N-0562 Oslo, Norway. Introduction contemporaneous platform deposits in Sweden are domi­ nated by a condensed limestone succession. In Norway, the The Tremadoc-Arenig Boundary interval is a crucial point Tøyen Formation is divided into two members: the lower in the evolution of several invertebrate groups, especially among the graptolites and the trilobites. In the graptolites, this change consisted most significantly in the loss of bithekae and a strong increase in diversity.

    Introduction to the Trilobites: Morphology, Ecology, Macroevolution and More By Michelle M. Casey1, Perry Kennard2, and Bruce S. Lieberman1, 3 1Biodiversity Institute, University of Kansas, Lawrence, KS, 66045, 2Earth Science Teacher, Southwest Middle School, USD497, and 3Department of Ecology and Evolutionary Biology, University of Kansas, Lawrence, KS 66045 Middle level laboratory exercise for Earth or General Science; supported provided by National Science Foundation (NSF) grants DEB-1256993 and EF-1206757. Learning Goals and Pedagogy This lab is designed for middle level General Science or Earth Science classes. The learning goals for this lab are the following: 1) to familiarize students with the anatomy and terminology relating to trilobites; 2) to give students experience identifying morphologic structures on real fossil specimens 3) to highlight major events or trends in the evolutionary history and ecology of the Trilobita; and 4) to expose students to the study of macroevolution in the fossil record using trilobites as a case study. Introduction to the Trilobites The Trilobites are an extinct subphylum of the Arthropoda (the most diverse phylum on earth with nearly a million species described). Arthropoda also contains all fossil and living crustaceans, spiders, and insects as well as several other extinct groups. The trilobites were an extremely important and diverse type of marine invertebrates that lived during the Paleozoic Era. They only lived in the oceans but occurred in all types of marine environments, and ranged in size from less than a centimeter to almost a meter across. They were once one of the most successful of all animal groups and in certain fossil deposits, especially in the Cambrian, Ordovician, and Devonian periods, they are extremely abundant.
