Fusulinids from Mexico, a biostratigraphical and paleogeographical review

This paper focuses attention on a bibliographical review about the Mexican fusulinids, with some new data. The Early Paleozoic and the Pennsylvanian o ceanizations are briefly described, and the work is mainly concerned with t he Early Permian (Wolfcampian-Leonardian), fossiliferous in the whole count ry. Moreover the Middle- and Late Permian are very badly exposed in Mexico. A paleobiogeographic reconstruction of Mexican Upper Paleozoic suspect ter ranes is also provided.
