【Abstract】 Numerous leaf compressions of Glyptostrobus europaeus (Brongn.) Ung. (Taxodiaceae) are found in Aquitanian (Lower Miocene) lignified clay localities Bolattam and Akzhar in the Southern Turgay, on the right bank of the Dulygaly_Zhilanshik river (Central Kazakhstan). The finely preserved lignified compression remains of leafy shoots make micro_morphological investigation feasible. Comparative studies of the epidermal features both living G. pensilis C. Koch and a new finding of G. europaeus from Early Miocene of Kazakhstan and illustrate their certain difference. The cuticular organization and epidermal features of fossil leaves, which have been compared with these of “the nearest living relative”, G. pensilis , were studied by scanning electron microscopy (SEM) and light microscopy (LM). The fossil leaves of G. europaeus from Kazakhstan are distinguished by stronger, than in living species, G. pensilis , developed “micro_papillae” (“Kristallucken”), visible in SEM as ring_like structures left on the outer surface of cuticle in both nonstomatal and stomatal zones.更多还原
