On Cuticular Compressions of Glyptostrobus europaeus (Taxodiaceae) from Kaydagul Formation (Lower Miocene) of the Central Kazakhstan

Sergei Vasilyevich VICKULIN, MA Qing-Wen, Sergey Glebovich ZHILIN, LI Cheng-Sen   


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.

摘要: 研究了哈萨克斯坦中部上渐新统/下中新统的欧洲水松(Glyptostrobus europaeus (Brongn.)Ung.)的枝叶微彤态结构,并利用扫描电子显微镜和光学显微镜与“现存最近亲缘种”——水松(G.pensilis C.Koch)的表皮特征进行了比较。
