An Early Permian flora with Late Permian and Mesozoic affinities from north-central Texas

Abstract: Early Permian (late Leonardian Series) plant assemblages from King, Knox, and Stonewall Counties of North-Central Texas are dominated by seed plants, some apparently congeneric with taxa heretofore known only from the Late Permian or the Mesozoic. Conifers are the dominant elements, including one or more species of Ullmannia, Pseudovoltzia liebeana, both known from the Late Permian Zechstein flora of Germany and England, Podozamites sp., characteristic of the Mesozoic, and Walchia sp., abundant in Early Permia… Show more

“…Each rare opportunity for plant preservation may have captured one temporal interval and the associated dominant plant. In this instance, it is probable that the conifers represent the wetter ends of a climatic gradient, given the abundance of walchian conifers in diverse Permian plant assemblages of North America (e.g., Read and Mamay, 1964;Mamay and Mapes, 1992;DiMichele et al, 2001) and Europe (Kerp and Fichter, 1985), including those with local patches of tree ferns, pteridosperms, and callipterids. In contrast, Supaia has rarely been reported as a landscape dominant.…”

“…The presence of Calnalia and other taxa yet to be described in the Sierra Madre terrane reinforces this model. Preliminary surveys of at least six localities in the Tuzancoa Formation suggest similarities with Permian floras of Texas (DiMichele et al, 2000(DiMichele et al, , 2001. Furthermore, walchian conifer remains found in Texas resemble typical Lebachioid conifers and Walchian Voltziales (DiMichele et al, 2000(DiMichele et al, , 2001Looy, 2007Looy, , 2007a.…”
