Palmoxylon Enochii sp. nov. from the Olmos Formation (Upper Campanian-Lower Maastrichtian), Coahuila, Mexico. Different types of flowering plants and conifers have been collected in the Olmos Formation, Upper Cretaceous (upper Campanian-lower Maastrichtian). A stem represents a new species of Palmoxylon Schenk (Arecaceae), P. enochii sp. nov.

The stem is well preserved revealing all the anatomical features identifiable to the modern arecoid palm (Phoenix). The fossil plant is characterized by the presence of cortical, dermal, sub-dermal and central zones with profuse roots in the bark region, indicating a basal part of the stem.

The paleofloristic composition from the northern portions of the Epicontinental Sea is relatively well known, but less intensive exploration in the south has precluded more detailed floristic comparison across the entire latitudinal span of the Sea.

Among these, a new permineralized infructescence is recognized based on its morphological and anatomical characters.
