Flora of The Late Triassic

• The Triassic was a crucial period of botanical evolutionary innovations and plant diversification. Key plant groups (Bennettitales, Czekanowskiales, Gnetales and several modern fern and conifer families) originated during this span of time, together with some taxa putatively related to angiosperms. The composition of the various plant assemblages shows a more homogeneous flora globally than during the Permian. Nonetheless two major floristic provinces are distinguishable during the Late Triassic (Gondwana and Laurussia) together with several subprovinces (two within Gondwana, nine within Laurussia), based on palyno- and macro-floras.The latter are differentiated by contrasting taxonomic composition and group abundances related to different climatic and regional environmental conditions. Many plant families and genera are widely distributed in the Late Triassic, at least in the respective hemispheres. Based on the array of preserved damage types on leaves and wood, insect faunas appear to have recovered from the end-Permian mass extinction by the Late Triassic, with a major expansion of herbivory in Gondwana. All modern functional feeding groups (FFG) were present by the Triassic, including external foliage feeding, piercing-and-sucking, galling, leaf mining and seed predation, with some evidence for the development of very specialized feeding traits and egg-laying strategies.
