Abstract Petrified wood is important evidence of forest type and past climate. Studies from mainly the Neogene of Turkey described many fossil woods, and revealed valuable information about the paleoenvironment structure and climate. This is the first occurrence of plant macrofossils belonging to the Middle Miocene Climate Optimum, a crucial period in Earth's history, found in Turkey. The purpose of the present study is to investigate, for the first time, the Middle Eocene Climate Optimum of Turkey through the first identification of two paleoxylotomical findings of Lutetian age from Central-North Turkey. After working on the thin wood sections, a new fossil genus of Lauraceae, Actinodaphnoxylon gen. nov. was described with a type species of Actinodaphnoxylon zileensis sp. nov. Another coniferous specimen was described as Pinuxylon cf. P. tarnocziense. These species indicate the presence of warm, humid rainforest and lower mountain forest 40–41 million years ago in the middle Black Sea region (Tokat-Zile) of North-Central Turkey.

来自土耳其中始新世气候最适气候的第一个古木分切证据

摘要 石化木是森林类型和过去气候的重要证据。主要来自土耳其新近纪的研究描述了许多化石木材，并揭示了有关古环境结构和气候的宝贵信息。这是土耳其首次发现属于中中新世气候最佳时期的植物大型化石，这是地球历史上的一个关键时期。本研究的目的是通过首次鉴定土耳其中北部卢特田时代的两个古划界发现，首次调查土耳其中始新世气候最适气候。在对薄木部分进行研究后，发现了樟科的新化石属 Actinodophnoxylon gen。十一月 描述了一种类型的 Actinodophnoxylon zileensis sp。十一月 另一个针叶树标本被描述为 Pinuxylon cf。P。特诺齐恩斯。这些物种表明 40-41 百万年前在土耳其中北部的黑海中部地区 (Tokat-Zile) 存在温暖、潮湿的热带雨林和低山森林。
