Download or read book Evolutionary Biology written by Max K. Hecht and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifteen volumes and one supplement have now appeared in the series known as Evolutionary Biology. The editors continue to seek critical reviews, original papers, and commentaries on controversial topics. It is our aim to publish papers primarily of greater length and depth than those normally published by society journals and quarterlies. The editors make every attempt to solicit manuscripts on an international scale and to see that no facet of evolutionary biology-classical or modern-is slighted. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061; Ghillean T.

Download or read book Taxonomy and Biostratigraphy of Middle and Late Triassic Elasmobranch Ichthyoliths from Northeastern British Columbia written by M. J. Johns and published by . This book was released on 1997 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diverse and abundant Middle and Late Triassic elasmobranch ichthyoliths (microscopic shark teeth and scales) coexisting with conodonts, ammonoids, and bivalves recovered from carbonates in the Peace River area of British Columbia provide an excellent biostratigraphic framework for Triassic strata. This report provides systematic descriptions and illustrations of Triassic elasmobranch ichthyoliths including seven species of teeth and 19 new form genera and 53 new form species of scales. A provisional ichthyolith zonation for the Middle and Upper Triassic is proposed for the Peace River area, and new approaches to ichthyolith identification are discussed. Results from this study demonstrate the use of ichthyoliths in basin analyses to data and correlate strata.

Download or read book Macurdablastus a Middle Ordovician Blastoid from the Southern Appalachians written by Thomas W. Broadhead and published by . This book was released on 1984 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Macurdablastus uniplicatus, n. gen. and n. sp., is the oldest reported blastoid and occurs in thinly interbedded shale and argillaceous packstone and wackestone of the Benbolt Formation (Middle Ordovician, Caradoc) in eastern Tennessee. It is distinguished by a single hydrospire fold in each hydrospiralium, a unique feature among early blastoid species. Poorly preserved ambulacral structures suggest at least a two-part lancet plate entirely underlain by part of the radial plate. Lack of preservation of the distal lancet and ambulacral side plates precludes definite ordinal assignment within the Blastoidea. Biotic associates of M. uniplicatus include abundant and diverse other echinoderms, sponges, bryzoans, brachiopds and a low-diversity skeletonized algal flora."--Pg. [1].
