Paleofile.com (net, info)
A taxonomic directory of Paleozoic and Mesozoic tetrapods and Cenozoic archosauromorphs
Here you will find a taxonomic list of names of animals that lived in the Paleozoic, Mesozoic and Cenozoic (only archosauromorphs), which if you click on the name will take you to a listing of what was found, how much, where and the age it lived. A locality listing of the taxa showing where it was found and what other animals that were found with it. This list is also split up into a listing via the ages. This will allow you to find out what animals lived with what at any age. Another is a listing of miscellaneous topics which I find interesting. And if you know which animal you are looking for but not where I have it listed you can always check the Index which will take you directly to the taxa list that it is in. I will also be adding illustrations for the individual taxa.
