The Paleointegration Project: The PaleoIntegration Project (PIP) is facilitating interoperability between global-scale fossil and sedimentary rock databases (e.g. The Paleobiology Database and the Paleogeographic Atlas Project), enabling a greater understanding of the life, geography and climate of our planet throughout the Phanerozoic. Databases can be searched via text and interactive maps, and by any combination of age, location, or content. Results can be plotted on present- and paleo- maps or downloaded for detailed analyses.
