Paleontology radiometric dating
However, to read any clock accurately we must know where the clock was set at the beginning.
Most people think that radioactive dating has proven the earth is billions of years old.
Wherever possible a series of maps is presented showing the size and position of land areas during each period. at Berkeley Fossils in Scotland : University of Aberdeen. at Berkeley The Dawn of Animal Life Exhibit : Miller Museum, Ontario Eukaryotic Cells : Single and multi-cell beginnings NMNH Virtual Tour - Early Life: National Museum of Natural History The bacterial creatures, which resemble "pond slime," were found in Northwest Australia and are estimated to be ca. Bacteria and algae like them are believed to have filled the primitive, super-heated oceans of the world during the earliest stages of life on this planet.
Also a small list of links is given for a description of the period and for museum and fossil exhibits related to it. Virtual Silurian Reef : Milwaukee Public Museum Paleontological Museum of Oslo Silurian Period Described and Silurian Fossils : Humboldt St. The Silurian Eurypterid Fauna: Pittsford, Western New York. Compiled by John Alroy in the course of his research, it consists of phylogenies, taxonomic histories, age-ranges, and body mass estimates for genera and species of Cretaceous and Cenozoic North American fossil mammals.
The knowledge was slow in coming, and scientists and scholars had some weird ideas.A great deal about the fossil record of life is available online to help you learn. at Berkeley Eocene Fossils : Coleoptera, Diptera and Flora Tiniest Primate Discovered : They lived in China 45 mybp. at Berkeley Willo, the Dinosaur with a Heart : North Carolina State University Paleontology: the Mesozoic : Web Directory The Solnhofen Limestone of Germany : Univ. For more information on fossils of pretty much any genera, go to the University of Berkeley's site and look up the phylum you're interested in, then click on the fossil record option for that taxon. Only about 400 million years ago did plants and animals leave the water and settle on dry land.But I urge you to read a couple of books and a journal or two and, if possible, to take an introductory course in paleontology. of Florida (see also Horse Transitionals) Paleontology: the Cenozoic : Excellent web directory The Age of Mammals : A Hypertext Book Museum of Paleontology : Univ. at Berkeley Pleistocene Animals : Illinois State Museum Study Guides : Fossils of Rancho La Brea (Los Angeles Tar Pits) Dino-to-Birds : Bird feathers and fossils. Whale Transitionals : Major period of whale transition. The Rhynie Chert, a formation near Aberdeen in northeastern Scotland, holds a trove of well-preserved fossils from the days shortly after that milestone in the history of life.
