Ofthe Kurotaki fauna, ten species of bivalves, two species of gastropods, and one sepcies each of amrnonite and brachiopod are discriminated. The Kurotaki limestone is considered, frorn these fossils, to be Mid-Skythian, probably early Owenitan in age. The presence of "Streblochendrki" matsushitai n. sp. and Pticatifera? sp. indicates a survival of the Paleozoic elements in the eraly Triassic. Re- examining other lower Triassic faunas, taxonomic emendation has also been made. Lastly the middle Skythian transgression in Japan has been suggested by reviewing the lower Triassic Systeni in Japan. Introduction and Acknowledgements It was as early as in 1883, when the German geologist E. NAuMANN, one of the pioneers in the study of the geology ofJapan, made a geological reconnaissance in Shikoku and noticed the occurrence of the Triassic fossils at Izumigatani about 6 km north of Ryoseki, Tosa Province (Kochi Prefecture) (NAuMANN and NEuMAyR, 1890, p.

    Rec. West. Aust. Mus. 1987,13 (4): 501-513 Upper Devonian conodonts associated with a large placoderm fish skull from the Canning Basin, Western Australia John A. Long* Abstract Conodonts retrieved from limestone encasing the skull of a large placoderm fish, from an unknown lo'cation in the south-eastern Canning Basin, indicate an age of mid-Famennian (toIIB) because of the concurrent presence of the following taxa: Nothognathella palmatiformis, Nothognathella sp. nov, A. Druce 1976,Palmatolepis glabra pectinata, P. quadrantinodosa inflexa, P. quadrantinodosa inflexoidea, P. marginifera s.s., Polygnathus triphyllatus, P. glaber s.s. and P. germanus s.s. The assemblage represents a palmatolepid-polygnathid biofacies dominated by palmatolepids, and is typical of muddy outer shelf to sandy inner shelf environ­ ments. The occurrence of certain taxa which have only been previously recorded in the Canning Basin from the Virgin Hills Formation, together with the lithology of the specimen, and palaeoecological information afforded by the conodonts, suggests that the specimen was derived from the uppermost section of the Virgin Hills Formation. Introduction A large dinichthyid placoderm fish skull has recently been described as a new genus, Westralichthys Long (1987) even though the exact location and lithological source of the specimen is unknown. A limited conodont fauna of 76 elements was recovered from dilute acetic acid preparation of the dinichthyid skull. The fauna contains a number of age diagnostic species which have been used to narrow the possible age and stratigraphic source of the specimen. It is significant that the conodonts indicate a much younger age for the skull than the well known lower Frasnian Gogo fish fauna (Gardiner and Miles 1975), also from the same region.

Collier of Invertebrate Fossils: Conodonta SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 9 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti­ tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com­ mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of profes­ sional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other in­ terested institutions and specialists throughout the world.

    THE UNIVERSITY OF KANSAS PALEONTOLOGICAL CONTRIBUTIONS May 15, 1970 Paper 47 SIGNIFICANCE OF SUTURES IN PHYLOGENY OF AMMONOIDEA JURGEN KULLMANN AND JOST WIEDMANN Universinit Tubingen, Germany ABSTRACT Because of their complex structure ammonoid sutures offer best possibilities for the recognition of homologies. Sutures comprise a set of individual elements, which may be changed during the course of ontogeny and phylogeny as a result of heterotopy, hetero- morphy, and heterochrony. By means of a morphogenetic symbol terminology, sutural formulas may be established which show the composition of adult sutures as well as their ontogenetic development. WEDEKIND ' S terminology system is preferred because it is the oldest and morphogenetically the most consequent, whereas RUZHENTSEV ' S system seems to be inadequate because of its usage of different symbols for homologous elements. WEDEKIND ' S system includes only five symbols: E (for external lobe), L (for lateral lobe), I (for internal lobe), A (for adventitious lobe), U (for umbilical lobe). Investigations on ontogenetic development show that all taxonomic groups of the entire superorder Ammonoidea can be compared one with another by means of their sutural development, expressed by their sutural formulas. Most of the higher and many of the lower taxa can be solely characterized and arranged in phylogenetic relationship by use of their sutural formulas. INTRODUCTION Today very few ammonoid workers doubt the (e.g., conch shape, sculpture, growth lines) rep- importance of sutures as indication of ammonoid resent less complicated structures; therefore, phylogeny. The considerable advances in our numerous homeomorphs restrict the usefulness of knowledge of ammonoid evolution during recent these features for phylogenetic investigations.

  • The Genus Microtis R. Br. (Orchidaceae): a Taxonomic Revision with Notes on Biology
    J. Adelaide Bot. Gard. 7(1): 45-89 (1984) THE GENUS MICROTIS R. BR. (ORCHIDACEAE): A TAXONOMIC REVISION WITH NOTES ON BIOLOGY R. Bates 38 Portmamock Street, Fairview Park, South Australia 5126 Abstract A taxonomic revision of Micro lis is presented in which nine species are recognised; M. globula is described as new. M. brownii, M. magnadenia and M. truncata are placed in synonymy with M. rara. M. media is treatéd as a synonym of M. unifolia. The biology, taxonomic affinities and distribution are considered for each species, a key is provided and a detailed description of each species is supplemented with illustrations. Introduction Since Robert Brown (1810) described Microtis there have been numerous taxa added but no complete revision has appeared, nor has any flora dealt with all species. Bentham (1873, p. 269) when discussing the difficulty of determining many Australian orchids, including Microtis, from dried material wrote, "It is to be hoped that the revision of these ... vvill be taken on byresident botanists who have the opportunity of studying them in the fresh state". With this in mind the present author has observed, photographed and collected all species of Microtis in the process of completing this revision. Plants were obtained from as many locations as possible and cultivated in Adelaide and populations of all Australian species studied in the field. Endophytic soil fungi on Microtis were isolated and identified by Dr J. Warcup (Waite Agricultural Research Institute). Chromosome counts were attempted but results were inconclusive. Loans were obtained from numerous herbaria (see acknowledgements). Types of all taxa were examined unless otherwise indicated in the text.

    A BIBLIOGRAPHY OF THE CONODONTS WITH DE- SCRIPTIONS OF EARLY MISSISSIPPIAN SPECIES By Grace B. Holmes Of the Eastern High School, Washington, D. C. INTRODUCTION The present contributions to the study of the conodonts was pre- pared at the suggestion of Dr. R. S. Bassler and under his direction in the paleontological laboratory of the United States National Museum where extensive collections of these toothlike structures were avail- able. As Doctors Ulrich and Bassler had just completed their paper on the classification of the conodonts and had applied their new classification in the description of an Upper Devonian fauna of western New York and an early Mississippian one from Tennessee, it was thought best that my work should carry these studies to the Mississippian rocks of Alabama and also include for the ready refer- ence by students illustrations of previously described species, with exception of three publications, and a bibliography of the group. The exceptions mentioned refer to the work of Bryant in 1921, Ulrich and Bassler in 1926, and Roundy in 1926, copies of which are still available to the student. ZOOLOGICAL AFFINITIES OF THE CONODONTS The affinities of the conodonts have been a subject of controversy almost since their discovery by Pander in 1856. That there was no doubt in Pander's mind as to their relationship may be ascertained from the title of his monograph. He studied the internal as well as the external structure of the fossils and saw in their formation fishlike characters somewhat of the Selachian type. The question concerning the affinities of these fossils seems to have had its birth in the mind of Dr.

  • Navajo Nation Species Accounts
    TOC Page |i PREFACE: NESL SPECIES ACCOUNTS Welcome to Version 4.20 of the Navajo Nation Endangered Species List Species Accounts which were produced to accompany The Navajo Nation’s February 13, 2020 revision to the Navajo Endangered Species List. The order of Accounts follows the February 2020 revision of the NESL, a copy of which is enclosed for reference. These Accounts were developed and distributed by the Navajo Natural Heritage Program, of the Navajo Nation Department of Fish and Wildlife, to help planners and biologists answer basic questions about species of concern during project planning. Your constructive comments are encouraged. Species Accounts are preliminary tools for project planning. Their target audiences are project planners, and biologists not familiar with: 1) species’ life histories and habitat in this region; and 2) Tribal and Federal protection requirements. Their purpose is to provide clear-cut information so that basic questions can be answered early in the planning process. Therefore, they should be reviewed as soon as potential species for the project area are identified. Accounts will prove useful early in the planning process, but they should be used as a quick-reference anytime. If protected species are found then more research and likely coordination with the Department will be necessary. At the end of each account is a short bibliography for planning the details of surveys, and answering more in-depth questions. For planning surveys and developing avoidance/mitigation measures, Accounts no longer distinguish between required and recommended activities; i.e. the terms ‘suggested survey method’ or ‘recommended avoidance’ are not used in V 4.20.
