Trilobite Paleogeography last revised 24 June 2008 by S. M. Gon III Biogeography involves the mapping and study of the patterns of distribution of organisms within and between the world's regions. The biogeography of plants and animals reflects their ecological requirements and the habitat niches they occupy. Some species are widespread, while others are restricted to certain regions of the globe. Paleogeography offers some of the same approach, but must take into account the fact of plate tectonics, and the changing of continental and ocean basin patterns over the course of hundreds of millions of years. The paleogeography of trilobites is particularly important because they were extremely diverse, were distributed all over the globe, and offer much insight on paleoenvironments and biostratigraphy Trilobites occupied marine environments from tropical equatorial to polar paleolatitudes. Some families of trilobites were narrow in their requirements. For example, the family Bathyuridae (Proetida:Bathyuroidea) was found only in paleoequatorial regions. Trilobite marine niches ranged from intertidal and nearshore to deep continental slopes. Because there was very significant continental movement during the Paleozoic Era, with continents drifting apart, as well as converging and joining, the distribution and evolution of trilobites over the nearly 300 million years of their existence reflects a complex paleogeography. For example, the locations of two famous trilobite-bearing sites Burgess Shale (Canada) and

Home Paleogeography of the Southwest Paleozoic The Age of Fishes Most of Arizona is underwater. Thick layers of limestone, sandstone and mudstone are developing as the ancient seas invade and recede. Pennsylvanian Period. 280 million years ago. Pangea, a consolidated landmass of all the continents as we know them today, is intact. Sedona Red Rocks are a result of Paleozoic geology. The iron oxides have leached from the volcanic layers into the sandstone, mudstone and limestone layers creating soft reds, pinks and peach colored layers below. Permian: This is the period of the Great Extinction. 90% of all life on Earth died during the final transition. The Atlantic Ocean is being "born" as the tectonic plates rotate, dramatically changing the climate. Arizona is about 14 degrees south of the equator at this point. Stand on the floor of Monument Valley and you'll be in touch with the Permian layer. Huge sand dunes form at the seas edge. Today, the remnants are the mesas, buttes and spires. Kaibab limestone deposits are forming in the northwest quadrant of Arizona, Utah, and southeast Wyoming.

Hållbarhetsindex Diskussion Links Links Press Paleogeography and Prehistory: From Ice Age to Iron Age Modern man came to Europe during the last ice age. Since he arrived, the major dramatic changes have been dramatic increases in temperature during two occasions, and dramatic transgression in most of Europe. Also, Scandinavia first got completely covered in ice, and then became ice free again. Since the deglaciation the land has been rising from the sea. During the late Ice Age, the southern North Sea was dry land where mammoths grazed on a large plain, protected by the hills of Dogger from the cold northern winds. 11,500 years ago large parts of it were flooded. This global transgression may have been very sudden, triggered by the drainage of a gigantic ice lake over Canada to the Gulf of Mexico through the Mississippi, which had huge spin-off effects on all ice sheets ending in the ocean.

PGAP Activities Permian Jurassic Movies, Slideshows and Maps ... Links THE PALEOGEOGRAPHIC ATLAS PROJECT UNIVERSITY OF CHICAGO About the Atlas Project We interpret paleogeography broadly to include all aspects of map reconstruction from paleo-continental orientations and tectonic considerations to the delineation of past topographic or bathymetric contours and the compilation of lithofacies data. In addition we use the reconstructions as base information for studies of past fossil distributions, and for climatic or oceanographic patterns as determined from the fossils, the sediments and from computer modeling studies. Our team has worked since the plate tectonic paradigm was introduced to compile information mainly from the literature on all aspects of global paleogeography. Moreover, we have pioneered the application of computer technology to paleogeographic map-making. click on image to enlarge The Paleogeographic Atlas Project in 2001 PGAP Publications (with links to abstracts) Jurassic slideshow sampler ( QuickTime ... Paleogeographic Maps (downloadable pdf files) Animations Successive paleogeographic maps often look very similar, just because continents move slowly in geologic time, mountains are uplifted gradually and shorelines generally do not advance or retreat significantly when viewed on a world scale. Animations are therefore necessary to bring out these subtle changes, and computer graphics are ideal for this purpose. Animations showing the general flow of the continental blocks through long intervals of geologic time are straightforward because the paleomagnetic information on the latitude and orientation of plates is reasonably well understood. Detailed paleogeographic maps, showing paleo-shorelines, and other paleogeographic contours are more problematic since depicting these accurately on closely spaced time steps is tedious and fraught with uncertainty. Nonetheless we have prepared a number of animations based on our detailed paleogeographic maps, and more are planned.

For the time being this page contains links to Ron Blakey's site on the evolution of the Colorado Plateau. His site, located at http://jan.ucc.nau.edu is the best site I have found so far, showing depictions of the changing depositional environments and geography of the Colorado Plateau. Ron Blakey and his graduate students are located in Flagstaff at Norther Arizona State University, so his maps seem to have their greatest accuracy in that location. Future Plans At some point, we would like to carry on the torch of this project by creating our own maps (or working with him?) which detail more specifically the paleogeography of the Northern Colorado Plateau. We would also like to add data points to the map which show (and link to) the stratigraphic columns and data which were used to recreate the given paleomaps.

Hållbarhetsindex Diskussion Links Links Press Atlantis Explained? You be the judge. Atlantis is a place Plato described in Timaios and Kritias as an example in a discourse on how society could be organized. This website accompanies the book on the right, but also contains much other material especially in Swedish (book-length treatises on European DNA and paleogeography). This site deals with two issues relating to Plato's Atlantis: 1. The topos of Atlantis: what, if anything, did he base it on? 2. The lesson of Atlantis: what, if anything, can we learn from this? While the second issue is surely the more interesting one, one can not approach it without first dealing with the first. The approach used by self-proclaimed "sceptics" is to instead pose the question if Atlantis is fact or fiction, and reply that it is fiction. However, that is a false dilemma : the reply is given beforehand by the nature of the question (their question is actually, "is everything true, or is there any detail that is false?," so it follows by necessity what the answer will be; scepticism is necessary, but so is fantasy in the thought process).

@import "/sitetech/global.css"; Skip navigation Home What's new? Search: History Research groups Graduate study Quaternary Discussion Group ... Contacts Cambridge Quaternary The Quaternary, the last 2.6 million years of geological time, saw major climatic changes which caused ice sheets to advance intotemperate latitudes. Repeated glacial episodes caused significant fluctuations in sea level, major geographical changes and major plant and animal population migrations. Sedimentary sequences record these changes in great detail and are central to unravelling past events. Cambridge Quaternary is a semi-informal research group of approximately 60 people within the University of Cambridge . Its constituent research groups are based in the Departments of Geography Plant Sciences Earth Sciences Archaeology and Zoology . Links also exist with the Department of Physics and the Scott Polar Research Institute . There is an excellent research environment at all levels, fostered by the staff (10 members), post-doctoral workers, and both Ph.D. and M.Phil. students pursuing interdisciplinary research in a wide range of Quaternary fields. This environment is unique in Britain, offering opportunities for research student training unequalled elsewhere, in terms of the range and quality of the expertise available. Cambridge Quaternary research Cambridge Quaternary embraces a wide ranging approach to Quaternary Research. General research themes are based around 'core' areas of staff interest. These include palaeooceanography, archaeology, geochronology, sedimentology, stratigraphy, palaeobotany, dendrochronology, micropalaeontology and palaeoecology. These mainstream interests are supplemented by the interaction of staff members with those from other University and external institutions to provide a diverse spectrum of topics. The understanding of palaeoenvironmental evolution is the central element underpinning all these themes; a foundation that provides a base from which to understand both present and future environmental and climatic change.but
