Studies on Mexican Paleontology
Unfortunately, much of the fossil reports from Mexico have been published in Spanish from local journals, which represent a language barrier to the international community. Even those localities that have been studied since the eighteen-century, such as the early Cretaceous San Juan Raya, have recently reported new fossil groups. Paleontological work in Mexico has been focused on providing important information for petroleum exploration and specific studies dealing with pollen, foraminifera, radiolaria, dinoflagellates, rudists, and ammonites. During the last few years, the number of contributions to the Paleontology of Mexico has increased considerably.
