Further contributions to the early Miocene forest vegetation of the Galatian Volcanic Province, Turkey

[摘要] Ten new petrified forest sites have been discovered on the Galatian Volcanic Province (GVP). The silicified woods, preserved in the lower Miocene Hançili and Pazar formations, represent a diverse plant assemblage that grew across western and central GVP during the Burdigalian, ca. 20-17 Ma. The assemblage comprises a total of 233 petrified woods collected from the 10 sites in and around Ankara (Beypazarı, Çamlıdere, Kızılcahamam) and Bolu (Kıbrısçık). Taxonomic identifications of the fossil wood floras suggest four distinct vegetational associations can be recognized on the GVP: (1) swamp associations of Glyptostrobus Endlicher, Sequoia Endlicher and Taxodium Richard; (2) riparian forest comprising palms, Salix L., Liquidambar L. and Quercus L. section Ilex ; (3) mesic-xeric woodland comprising Acer L.,Quercus L., Pinus L. and Juniperus L.; and (4) mixed coniferous-angiosperm forest comprising Picea A. Dietrich, Cedrus Trew., Pinus, Juniperus L. and Podocarpus L’Herit (ex Pers.) alongside. These associations support the idea that the landscape was varied and the climate warm and frost free.
