Abstract

The early and middle Miocene in Turkey was characterised by a warm climate and a diversified and rich vegetation. Many fossil angiosperm genera have been identified from this period. The present study re-examined previously identified genera and identifed new samples of angiosperm wood remains. The studied material included thin sections housed at the Department of Forest Botany, Division of Forest Engineering, Faculty of Forestry, Istanbul University-Cerrahpasa, and also new ones. Twelve new species are described: Liquidambaroxylon efeae Akkemik sp. nov., Eucarpinoxylon kayacikii Akkemik sp. nov., Ostryoxylon gokceadaense Akkemik sp. nov., Quercoxylon yaltirikii Akkemik sp. nov., Cryptocaryoxylon grandoleaceum Akkemik sp. nov., Fraxinoxylon beypazariense Akkemik sp. nov., Prunoidoxylon prunoides Akkemik sp. nov., Populoxylon sebenense Akkemik sp. nov., Salicoxylon galatianum Akkemik sp. nov. Aceroxylon aceroides Akkemik sp. nov., Ulmoxylon kasapligilii Akkemik sp. nov. and Zelkovoxylon crystalliferum Akkemik sp. nov. In addition, four previously described species are documented for the early and middle Miocene: Pistacioxylon ufukii Akkemik and I. Poole, Fagoxylon radiatum Süss, Laurinoxylon litseoides Süss and Platanoxylon catenatum Süss and Müller-Stoll. In addition to the species descriptions, identification keys are given for all the genera recognised in this study, including all currently known fossil species of the respective fossil genera. These keys hold important new information, as they place the fossil species from Turkey in a wider taxonomic and biogeographic context. The results show that in the early and early-middle Miocene of Turkey a rich woody flora existed in well-drained upland or lowland and riparian areas. This flora comprised subtropical taxa along with warm-temperate taxa indicative of seasonality of rainfall as well as transitions to xeric conditions in the early Miocene.
土耳其中新世早期和中期被子植物木材记录的重新研究和新种描述
土耳其中新世早期和中期气候温暖,植被丰富多样。许多被子植物属的化石已经从这一时期被鉴定出来。本研究重新检查了先前确定的属,并确定了被子植物木材遗骸的新样本。研究材料包括伊斯坦布尔大学塞拉赫帕萨分校林业学院森林工程系森林植物系的薄片,以及新的薄片。描述了12个新种:Liquidambaroxylon efeae Akkemik sp.nov.,Eucarpinoxylon kayacikii Akkemik.nov.,Ostroxylon gokceadaense Akkemix.nov.,Quercoxylon yaltiriki Akkemik.nov.,Cryptocaryoxylon grandolaceum Akkemiks.nov。,Salicoxylon galatianum Akkemik sp.nov.Aceroxylon aceroides Akkemik.nov.,Ulmoxylon kasapligilii Akkemiks.nov.和Zelkoxylon crystiferum Akkemik.nov.此外,中新世早期和中期记录了四个先前描述的物种:Pistaxylon ufukii Akkemik/I.Poole,Fagoxylon radiatum Süss,Laurinoxylon litseoides Süss和Platanoxylon catenatum SüS和Müller Stoll。除了物种描述外,还提供了本研究中识别的所有属的识别密钥,包括各自化石属的所有目前已知化石物种。这些钥匙包含了重要的新信息,因为它们将土耳其的化石物种置于更广泛的分类学和生物地理学背景下。结果表明,在土耳其中新世早期和中期,在排水良好的高地或低地和河岸地区存在着丰富的木本植物群。该植物群包括亚热带分类群和暖温带分类群,表明中新世早期降雨的季节性以及向xeric条件的转变。

期刊介绍: Acta Palaeobotanica is an international journal edited in English by the W. Szafer Institute of Botany, Polish Academy of Sciences, Kraków, since 1960, which publishes original palaeobotanical, palynological, palaeoecological and palaeophytogeographical papers, monographs, review and discussion articles and book reviews. It is the only journal in the Central and Eastern Europe publishing papers from all fields of palaeobotany. The journal is published regularly in one volume per year, with two numbers.
