Digital Atlases

The Digital Atlases of Ancient Life are online field guides to fossils from particular time intervals and regions of the United States. Each Digital Atlas provides overviews of hundreds of species, as well as high-quality images and occurrence information to help you identify your fossil discoveries. An overview of the Digital Atlas field guide project was published by Jon Hendricks, Alycia Stigall, and Bruce Lieberman (2015) in the open access journal Palaeontologia Electronica.
