Evolution and paleobiogeography of mangroves

Marine Ecology, 2019
AbstractWe reviewed the geological record of mangroves based on fossil pollen, fruits, and wood evidence ofNypa,Avicennia,Sonneratia, Rhizophoraceae, and mangrove associates to trace the origin, distribution, extinction, and range contraction of paleo‐mangroves during the Late Cretaceous–Miocene time.

Paleobiogeography of Chitinozoa

1977
Abstract 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 ...

Paleoenvironment, Tectonics, and Paleobiogeography

2018
The Earth experienced dramatic transformations during the Cenozoic, with changing sea levels, climate, and tectonic events having major influences on the global biota. In South America, loss of the connection between Patagonia and Antarctica, Andean orogeny, and formation of the Isthmus of Panama defined the continent, as we know it today. These events

Assessment of quantitative techniques in paleobiogeography

Marine Micropaleontology, 1982
Abstract 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 ...

What Is Paleobiogeography?

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 ...

Biostratigraphy and Paleobiogeography of the Proterozoic

1992
Biostratigraphy 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)

Defining Areas in Paleobiogeography

2000
The 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.

The Paleobiogeography of Pennsylvanian Crinoids and Blastoids

2012
Historically, 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.
