Glossary of Invertebrate Paleontology Terms From the list below, select the letter that corresponds to the first letter of the word that you wish to look for. A B C D ... Z Return to Topic List A abdomen - Region of the body furthest from the mouth. In insects, the third body region behind the head and thorax. ambulacra - Row of tube feet of an echinoderm. anus - End of the digestive tract, or gut, through which waste products of digestion are excreted, as distinct from the mouth. B benthic - Organisms that live on the bottom of the ocean are called benthic organisms. They are not free-floating like pelagic organisms are. biramous - Arthropod appendages that are biramous have two branches, an outer branch and an inner branch. These branches may have separate functions; in crustaceans, for instance, the inner branch of a leg is used for walking, while the outer branch may be paddle-shaped or feathery and often functions as a gill. Contrast with uniramous. blood - Fluid which circulates throughout the body, distributing nutrients, and oxygen as well in many animals. book lung - A set of soft overlapping flaps, covered up by a plate on the abdomen, through which oxygen is taken up and carbon dioxide given off. Characteristic of many terrestrial arachnids such as scorpions and spiders.

Paleozoic.org is sponsored by Notkin.net : A graphics house specializing in art direction and web design for clients in natural history and earth sciences. Paleozoic.org's Esoteric Guide to the WWW of Paleontology There are hundreds, perhaps thousands, of paleontology sites on the web: commercial, educational, reference resources, online publications, virtual museums and more. A fossil enthusiast could spend a year visiting all of them. Reference and Educational Resources Fossil Collections of the World Detailed information about the geologic time scale, with characteristics of each era; classic fossil sites; important paleontologists in history, and much more. An outstanding and extensive resource. Fossils, Rocks, and Time Presented by the U.S. Geological Survey, this is a complete online edition of the book by Lucy E. Edwards and John Pojeta Jr. It is a superior educational site for younger readers, and helps to put geologic time in perspective. Their illustrated geologic time scale is beautiful (look closely). Other features: explanation and origin of geologic terms; discussions about evolution and the Law of Fossil Succession; diagrams, charts, and photographs; numeric versus relative time scale, and much more. Many adults will find this excellent site useful too. Highly recommended.

INDEX FOSSILS Index fossils are commonly found, widely distributed fossils that are limited in time span. They help in dating other fossils found in the same sedimentary layer. For example, if you find a fossil from an unknown era near a fossil from a known time, you can assume that the two species were from about the same time. Examples of index fossils include: Ammonites were common during the Mesozoic Era (245 to 65 mya), They were not found after the Cretaceous period, as they went extinct during the K-T extinction (65 mya). Brachiopods (mollusk-like marine animals) appeared during the Cambrian (540 to 500 mya); some examples still survive.

University of Chicago Press:Chicago, 342pp. The fossils are arranged in standard stratigraphic order - oldest at the bottom, youngest at top. These specimens are only the cephalon - the "head" of a trilobite. Other changes are observed in the shape of the thoracic segments of these species.

88. Kootenay Rockies Fossil, Trilobite And Paleontology Tours Fossil, paleontology, Geology Tours and Vacations examine rare trilobitesin Kootenay Rocky Mountains, near Cranbrook, British Columbia, Canada. http://www.rockiestours.com/home.html

WELCOME TO THE ROCKIES! We offer spectacular mountain tours in the Mackay Group of the Rocky Mountains. All our tours are guided and originate in Cranbrook, British Columbia. While on our many different tours you will see beautiful mountain vistas and have the opportunity to view many species of wildlife. Wildlife found in the area include Grizzly Bear, Black Bear, Elk, Moose, Mule Deer, White Tail Deer, Mountain Goat, Coyote, and birds such as the Bald Eagle. Seven new species of trilobites have been found at our site. They are found nowhere else in the world. These trilobites are Upper Steptoean (Upper Cambrian) in age. The new species are documented in the Paleontological Society Memoir 49. This submission was made by Brian Chatterton of the University of Alberta and Rolf Ludvigsen of the Denman Island Institute for Research on Trilobites. The new species are Wujiajiania sutherlandi, Aciculolenus palmeri, Labiostria westropi, Burnetiella leechi, Hedinaspis canadensis, Pterocephalia norfordi, and Irvengella Species "A". ** Note: Two specimens located in the fall of 2001 allowed for the identification of Irvengella Species A as a new species. This new species will be the subject of a new submission to the Society.

89. Networking In Paleontology's "Dark Ages" Networking in paleontology's Dark Ages Howard Bloom 22.04.1997 Trilobitesdominated the period from 600 million to 500 million years ago. http://www.heise.de/tp/english/special/glob/2127/1.html

Networking in Paleontology's "Dark Ages" Howard Bloom History of the Global Brain III Since software innovations - new forms of behavior and interaction - leave few fossil records, and since paleontologists have been virtually blind to proterozoic social activity, the record seems barren. But evidence indicates that intimate forms of organization were undergoing long and ever more intricate trial periods, resulting in multi-cellular life forms and brains as internets. Vitalism is not the only alternative to Darwinism. I propose a new option, that of cooperative evolution based on the formation of creative webs. The emergence of the new picture involves a shift from the pure reductionistic point of view to a rational holistic one, in which creativity is well within the realm of the Natural Sciences. Eshel Ben-Jacob I n our previous episode , I laid out evidence indicating that the global brain foreseen by computer-futurists already existed 3.5 billion years ago. I attempted to demonstrate how the biology of the primitive cyanobacterium equipped it to act as a component in a parallel-distributed intelligence. The result: a social colony capable of networking data, solving problems, creatively retooling genomes, and of transmitting and receiving genetic upgrades via a worldwide web.
