Intended as a public resource for scientists around the world, the Paleobiology Database "has been organized and operated by a multi-disciplinary, multi-institutional, international group of paleobiological researchers. Its purpose is to provide global, collection-based occurrence and taxonomic data for marine and terrestrial animal and plants of any geologic age, as well as Web-based software for statistical analysis of the data." Site visitors can search for Fossil Collection Records, Taxa Classifications, Taxa, and Published References. The site also allows visitors to view different time scales; and offers a detailed download request form with a variety of Options, Occurrence Fields, and Collection Fields. In addition, the website supplies information about the Database including contacts for participating researchers; options for analyzing data with maps, data summary tables and a diversity curve; and examples of Entry Forms for References, Main Collection Records, and Taxonomic Occurrences. Be sure to check out the animated world map depicting the dramatic growth of the Database from 1999 to the present.
