“…We consider them as taxodioid wood. Anatomical features of the specimens are rather similar to Sequoioxylon from Turkey (Özgüven-Ertan 1983, Akkemik et al 2005, 2009, 2019, Akkemik and Sakınç 2013, and Taxodioxylon from Turkey (Akkemik et al 2009).…”

Abstract Taxodioxylon Hartig (emended by Gothan 1905) was widely described from the late Oligocene of the European part of Turkey (Thrace) and the early Miocene of greater Turkey, Anatolia. Glyptostroboxylon Conw. was also described from the early Miocene of central Anatolia. The purpose of this paper is to present a more detailed extended history of these two genera up to the late Miocene (Tortonian) with new descriptions from the Galatean Volcanic Province in central Turkey. The wood identification showed the presence of two fossil species; Glyptostroboxylon rudolphii Dolezych et Burgh and Taxodioxylon gypsaceum (Göpp.) Greguss. In conclusion, the swamp and lowland warm-temperate forest composition including Glyptostroboxylon and Taxodioxylon in the Galatean Volcanic Province, continued from the early Miocene (Burdigalian) to the late Miocene (Tortonian).

“…Further, this fossil species was identified from the late Miocene fossil woods found in the east Galatian Volcanic Province (Akkemik and Acarca Bayam, 2019) and from the mid-late Miocene of Kütahya in central Turkey (Akkemik et al, 2019a). Finally, this fossil species had a wide distribution area during the early-middle Miocene to the late Miocene in the swamp areas of central Turkey.…”

“…All these woods showed most stable wood characteristics from Paleocene to Pliocene. Based on the recent discussion on the names of Taxodioxylon and Sequoioxylon (Blokhina et al, 2010;Tian et al, 2018), I prefer to use the name Taxodioxylon, as I used in my recent studies (Akkemik, 2019 andAkkemik et al, 2019a). The results showed that T. gypsaceum was identified from different time periods from Paleogene to Pliocene.…”

For identification at the species level, the published descriptions given in the relevant discussion parts of the related species were used.…”

Until now, a considerable number of Miocene conifer trees has been determined using fossil wood identification. Some studies on fossil wood identifications have revealed the need to reconsider certain fossil wood species definitions. The present study aimed to re-analysis the conifer wood identifications (Cupressaceae), which were described as genus, and performed necessary revisions in the descriptions. All studies were conducted on thin sections used in former studies, and detailed investigations were performed. As result, Cupressinoxylon pliocenica Akkemik, 2019, Glyptostroboxylon rudolphii Dolezych & van der Burgh, 2004, and Taxodioxylon gypsaceum (Göppert) Kräusel, 1949, were described in Turkey. This study showed that these three fossil species had wider distribution areas and lived in a very wide time interval from mainly early Miocene to Pliocene in Turkey.

Özet Trakya Havzası'nın güneybatısında yer alan Malkara-Keşan çevresinde silisleşmiş ağaç örnekleri, Geç Oligosen-Erken Miyosen yaşlı Danişmen Formasyonuna ait karasal sedimanlar içerisinde bulunmaktadır. Türkiye'nin çeşitli bölgelerinde tespit edilen, özellikle Tersiyer yaş aralığındaki silisleşmiş ağaçların oluşumları, Malkara-Keşan bölgesinde de olduğu gibi bölgedeki etkin volkanizma faaliyetleri ve eşzamanlı sedimantasyonla ilişkilidir. Silisleşmiş ağaç örneklerinde enine, teğet ve radyal yönde kesitler alınarak, bunlarda polarizan mikroskop altında mineralojik-petrografik çalışmalar yapılmış ve silisleşmiş ağaçların tamamına yakınında silisin çeşitli formlarda geliştiği gözlenmiştir. Ayrıca, mikroskop altında tespit edilen silisin mineral tür ve amorf oluşumlarının tayinleri X-Işınları Difraktometresi (XRD) analizleri ile de desteklenmiştir. Buna göre Opal-A, Opal-CT, kalsedon ve kuvars türü amorf/mineralojik oluşumlar saptanmıştır. Silisleşmiş ağaçlardan alınan ince kesitler üzerinde yapılan çalışmalarla fosil ağaç cins/türleri tespit edilerek o dönemin paleobotanik yorumları yapılmıştır. Silisleşmiş ağaç örneklerinin tanısıyla Glyptostroboxylon rudolphii bulgusu, Oligosen-Erken Miyosen döneminde Trakya'da ilk kez, cf. Quercoxylon caucasicum ve cf. Ginkgoxylon lesboense türleri ise Türkiye'de ilk defa bu çalışma ile tanımlanmıştır. Trakya'da daha önce varlığı bilinen diğer tür ise Taxodioxylon gypsaceum türüdür. Bu türlerin yaşam ortamları göz önüne alındığında, bölgede Oligosen-ErkenMiyosen dönemlerinde su kenarı-bataklık koşullarının ve subtropikal iklimin hâkim olduğu söylenebilir.
