This site, maintained by the University of California Museum of Paleontology contains one of the very best collections of on-line paleontology exhibits and scientific resources on the web. A hypertext link to Information for First-time Visitors streamlines access to the site. Extensive navigation pages for the three main areas of interest: Phylogeny, Geology, and Evolution (under construction), give the user instructions on how to navigate their way around. Numerous images of everything from hadrosaurs (duck-billed dinosaurs) to Leptospira (a bacteria) make this an ideal site for research and educational purposes.
