La flora triásica de México

Abstract

Mexican Triassic floras are of limited geographical distribution. Only a few localities contain abundant plants of this age, since well-preserved Triassic plants are found only in four localities in the States of Sonora, Tamaulipas, San Luis Potosí and Hidalgo, all from Upper Triassic sediments. Among the dominant plants of these floras, there are cycadophytes, ferns and pteridosperms, while equisetals and conifers are rather scarcely represented. This paper includes general aspects of the Triassic plants, as well as a review of the stratigraphy and of the macroscopic vegetation of the Mexican Upper Triassic continental rocks.
