Terebratulide occurrences

The geographic occurrences of Devonian terebratulide genera. These occurrence data were compiled previously in an exhaustive search of the published literature for a study of Paleozoic terebratulide latitudinal diversity gradients (Fitzgerald and Carlson 2006). The data set consists of 476 occurrences, resolved to 5 degree paleolatitudinal bins, ranging from 85 degrees S to 45 degrees N.
