The Atlantic’s CITYLAB blog has a story about an interesting effort to map “The United States of Fossiliferousness”.  Cason Clagg is a fossil fanatic.  He’s a software developer and lives in Southern Oklahoma.  He wants to map where fossils are found.  He used data from the Paleobiology Database, which coincidently was inspired by David Raup’s work at the University of Chicago.   There are several versions of the map.  And, for those of you with an iphone, he plans to release an iphone app at some point in the future.
