Upper Cretaceous flora of Karakumzholy, northeastern Aral Region

Upper Cretaceous plant impressions from the reddish gray sandy and clayey deposits of the Zhirkindek Formation of the Karakumzholy locality (the Lower Syr Darya Uplift, Kazakhstan) were studied. This Turonian flora includes two species of fern (Filices) and several angiosperm species. The angiosperms Ettingshausenia cuneifolia (Bronn) Stiehler (described previously as Platanus cuneifolia Bronn) and Trochodendroides arctica (Heer) Berry dominate at the locality. The former species is a typical representative of the Upper Cretaceous flora of the Euro-Sinian subtropical phytogeographic region of Eurasia, while the latter belongs to the temperate Siberian-Canadian phytogeographic region.
