The mission of the Ithaca, N.Y.-based Paleontological Research Institution (first mentioned in the January 10, 2003 NSDL Scout Report for Physical Sciences) is "to increase and disseminate knowledge about the history and evolution of the Earth and its life." The Paleontological Research Institution (PRI) website offers brief information about the work of several different researchers including mastodon-related research, and studies looking at turritelline gastropods, and hard-to-identify fossils. Site visitors who are just learning about paleontology will find that the information is presented in an accessible manner. The site also provides information about the rich PRI collections, and descriptions of a variety of related publications for amateurs and professionals. In addition, the site contains detailed Instructions for Authors wishing to submit manuscripts to _Bulletins of American Paleontology_ or _Palaeontographica Americana_. This site is also reviewed in the June 24, 2005 _NSDL Life Sciences Report_.
