The Digital Atlas of Ancient Life just released a free app for iPhones and iPads. The app is an electronic field guide that has an interactive digital atlas for the paleontology time periods: Neogene, Pennsylvanian, and Ordovician.
The Digital Atlas of Ancient Life Electronic Field Guide App is part of the project "Digitizing Fossils to Enable New Syntheses in Biogeography - Creating a PALEONICHES-TCN" that is supported by a grant from the National Science Foundation to principal investigators Dr. Bruce Lieberman (University of Kansas), Dr. Alycia Stigall (Ohio University), and Dr. Jonathan Hendricks (San Jose State University).
For additional information about the project, please see the recently published open-access paper by Hendricks, Stigall, and Lieberman (2015) in Palaeontologia Electronica.
