Laurozamites, a new genus and new species of bennettitalean leaves from the Late Triassic of North America

Abstract

The Carnian—and/or Norian?—Santa Clara taphoflora from Sonora, Mexico, yields a large number of bennettitalean leaves. Most common are those placed here in Laurozamites gen. nov. Species are described as L.fragilis (Newberry) comb. nov., L. yaqui sp.nov., L. pima sp. nov. and L tarahumara sp. nov.—with two varieties, tarahumara var. nov. and dubiusvar. nov. The first three species are differentiated mainly according to the dimensions of the pinnae measured in specimen-rich palaeodemes, while the fourthis distinguished by the low venation density… in order to continue, download the full paper in PDF.
