This book was released on 1994 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biometric analyses of well-localized specimens of the trilobite Dikelocephalus from the St. Lawrence Formation (Upper Cambrian), northern Mississippi Valley, suggest that all specimens belong to a single, highly variable morphospecies, D. minnesotensis. A complex pattern of ontogenetically-related and ontogeny-independent variation produced a mosaic of morphotypes, which show greater diversity than previously recorded within trilobite species. There is considerable variation within collections made from single beds. Variations of characters among collections are mosaic, and are clinal in some cases. Patterns of variation within Dikelocephalus cannot be related to lithofacies occurrence. There are no obvious temporal variations in D. minnesotensis within the St. Lawrence Formation, but some Dikelocephalus from the underlying Tunnel City Group may belong to a different taxon. The validity of this early taxon is questionable due to a lack of available material. The mosaic pattern of variation in Dikelocephalus mimics that documented at higher taxonomic levels in primitive libristomate trilobites, and helps explain difficulties in providing a workable taxonomy of primitive trilobites. Results caution proposition of evolutionary scenarios that do not take account of intraspecific variation. The recovery of dorsal shields of Dikelocephalus permits the first detailed reconstruction of the entire exoskeleton. The systematics of the genus is revised and twenty-five species are suppressed as junior synonyms of D. minnesotensis.

Available in PDF, EPUB and Kindle. Book excerpt: The significant published literature on the neobiology, paleobiology, and ethnobiology of the mammalian orders Sirenia and Desmostylia is exhaustively cataloged in approximately 4590 main entries alphabetized by the author. Both technical and popular works are included, and many entries are annotated. The earliest work cited is a letter by N. Syllacio published in 1494 or 1495, describing Columbus's second voyage to the New World. The effective closing date of the bibliography was 1 May 1994. Six appendices list serial publications devoted to Sirenia, additional sources for history of sirenology and sirenian conservation, coins and postage stamps depicting sirenians, a comprehensive classification and synonymy of sirenians and desmostylians, a summary of the nomenclature of the Recent species of sirenians, and an alphabetical list of the species-group names that have been applied to sirenians and desmostylians. An extensive index is provided, employing 1059 subject headings and cross references; the subject headings include all Linnaean names and combinations ever employed for sirenians and desmostylians, as well as names of all reported sirenian food plants and parasites. More than 40% of the main entries are fully indexed, and many others are partially indexed, yielding a total of over 13,950 index entries. Each complete index entry includes author and date of the work cited, a brief annotation describing the content of the work as it pertains to the indexed subject, and a page reference for the material pertaining to that subject.
