Paleobiogeography of Chitinozoa
1977Abstract Biogeographic distribution of Ordovician to Silurian Chitinozoa of the ancient Atlantic borderlands is discussed. The classification system followed is that of Jansonius (1970). The genus Conochitina is restricted to forms with a mucro or copula; some forms designated Conochitina by previous authors are assigned to Euconochitina ...

Assessment of quantitative techniques in paleobiogeography
Marine Micropaleontology, 1982Abstract A series of multivariate methods has been compared to assess their effectiveness in extracting essential information out of a complex micropaleontological data-set. The data-set used for this experiment consists of relative frequencies (percentages) of Miocene coccolith taxa or groups of taxa in cores of the Deep Sea Drilling Project (DSDP ...

2000
The field of paleobiogeography is derived in direct lineage from its close intellectual cousin, biogeography, a scientific discipline that had its birth in the adventurous and exploratory urges of humankind. When people traveled to far-off lands centuries ago they discovered, much to their surprise, that the plants and animals of these lands, as well ...

Defining Areas in Paleobiogeography
2000The discipline of biogeography, as has been emphasized repeatedly, was developed because the same species are not found everywhere. Different regions do not have the same complement of species and, moreover, the climate alone is not sufficient explanation for why species are found where they are.

Biostratigraphy and Paleobiogeography of the Proterozoic
1992Biostratigraphy deals with bodies of rock defined or characterized by their fossil content. Biogeography is concerned with the geographic distribution of organisms. The basic biostratigraphic principles and concepts now in use were developed in the early- to mid-nineteenth century by pioneers such as William Smith (1769–1839), Georges Cuvier (1769–1832)

The Paleobiogeography of Pennsylvanian Crinoids and Blastoids
2012Historically, Pennsylvanian crinoid and blastoid paleogeography has been poorly constrained. Recent discoveries of Pennsylvanian faunas from Queensland (eastern Australia), Algeria, Western China, and Iran contribute to a worldwide data set that permits a more complete analysis of Pennsylvanian echinoderm paleogeography.

The biostratigraphy and paleobiogeography of Maastrichtian inoceramids
1996The global distribution of Maastrichtian inoceramids is now known in enough detail that the patterns of disappearance can be used to place first-order constraints on paleoceanographic changes that may have occurred during that age. The Inoceramidae is an excellent group to focus on in a study of Maastrichtian events for the following reasons: (1) they ...

Continental Paleobiogeography as Phylogenetic Evidence
2006Morphological convergence between members of clades isolated on different landmasses can mislead phylogenetic analyses, and can imply intercontinental dispersals that are unlikely given reconstructed paleogeography. It is argued here that paleobiogeographic data, like chronostratigraphic data, are relevant to the process of inferring phylogenetic ...
