A new methodological approach on Lauri-noxylon and the importance of the oil &/or mucilage cells TALK IN SESSION S5 Mantzouka, Dimitra1 fdmantzouka@yahoo.gr]; Sakala, Jakub2; Karakitsios, Vasileios1 'Department of Historical Geology - Paleontology, National and Kapodistrian University of Athens, Athens (Greece) institute of Geology and Palaeontology, Charles University of Prague, Prague (Czech Republic) Wood anatomy of several specimens oï Laurinoxy-lon from the Tertiary of southern part of Lesbos Is-land (Greece) Kadan - Zadni Vrch Hill and Jâchy-mov (Czech Republic) and Ipolytarnóc (Hungary) was observed, mainly with respect to the type and distribution of idioblasts. These observations to-gether with the published descriptions and data from the InsideWood Database, both modern and fossil, gave birth to a new methodology focused on the identification and classification of Laurinoxy-lon. Our observations on the exact occurrence of the oil &/or mucilage cells (in connection with the ray parenchyma, or with the vertical strand paren-chyma or isolated from parenchymal tissues and embedded between the fibers or several combina-tions) allowed us to make four main groups of Lau-rinoxylon. On the other hand, presence of marginal bands of axial parenchyma, aliform to aliform-con-fluent paratracheal parenchyma, rays higher than 1 mm, exclusively homocellular rays, ring-porous wood or absence of idioblasts (oil &/or mucilage cells) can exclude a fossil lauraceous wood from being attributed to Laurinoxylon. In this context, the existence of crystals and S1O2 along with the occurrence of crystalline masses inside the fibers of some species was also highly evaluated, as also the observation of septate fibers. The newly proposed methodology on Laurinoxylon shows that taxo-nomical information, palaeobotanical data, and ex-act botanical affinities can help to classify it, but also to exclude many fossil woods from that fossil genus which used to be treated as a 'waste bin', which surely overestimates its importance in the Cenozoic fossil wood record. -31 August 2014 Abstract Book The research was supported by the grants GAI4-23108S andPRVOUKP44. Gavdos Island palaeoflora: A newly recov-ered late Neogene flora of the Eastern Med-iterranean (Greece) POSTER IN SESSION S22 Mantzouka, Dimitra1 fdmantzouka@yahoo.gr]'; Kvacek, Zlatko2; Teodoridis, Vasilis3; Utescher, Torsten4; Tsaparas, Nicolaos1 ; Karakitsios, Vasileios1 'Department of Historical Geology-Paleontology, National and Kapodistrian University of Athens, Athens (Greece) 2Institute of Geology and Palaeontology, Charles University of Prague, Prague (Czech Republic) * Department of Biology and Environmental Studies, Charles University of Prague, Prague (Czech Republic) 4Rheinische Friedrich-Wilhelms-Universität Bonn and University of Bonn, Bonn and Senckenberg Research Institute. Frankfurt /M (Germany) The study of more than 100 leaf impressions from the Metochia section, Gavdos Island, Greece, re-vealed a recently recovered late Miocene pal-aeoflora from the southernmost part of Europe. Fossilifcrous strata - sapropels - of early to middle Tortonian age (9.6-9.1 million years b. p.) yielded a plant assemblage consisting of 3 conifers and ca 30 fossil species of angiosperms belonging to sub-tropical to warm temperate evergreen or deciduous shrubs and trees including legumes. The number of the identified specimens was sufficient to allow an application of several palaeoenvironmental tech-niques (phytosociological approach and Integrated Plant Record analysis, Leaf Margin Analysis tech-nique. CLAMP analysis and Coexistence Ap-proach). The results obtained from the Gavdos pal-aeoflora expand our knowledge about the late Neo-gene floras of the Mediterranean and complement previous studies recently accomplished in south-ernmost Greece, namely in Crete (Makrilia, Vrysses and Pitsidia). This research has been co-financed by the European Un-ion (European Social Fund ESF) and Greek national funds through the Operational Program * 'Education and Lifelong Learning" of the National Strategic Reference Framework (NSRF) - Research Funding Program: THAL/S-UOA- "Messinian Salinity Crisis: the greatest Mediterranean environmental perturbation and its reper-cussions to the biota ' ' and supported by the grants J 13/98113100006, MSM002162085 andPRVOUK P44. 154
