Many Pinuxylon W. Gothan 1905 (formerly described as Lesbosoxylon S & uuml;ss & Velitzelos 2010) fossil woods have been identified from different parts of T & uuml;rkiye. After five species were described from Lesbos Island and one new species from Eastern Anatolia, more recent studies have shown that this fossil-genus comprises more species and had a wider range in the Early Miocene through the Aegean Islands and Anatolia. The purpose of the present study was to summarize the state-of-the-art of the fossil-species of this genus from the Early Miocene of T & uuml;rkiye. Thin sections housed in the fossil collections of the Department of Forest Botany, Faculty of Forestry, & Idot;stanbul University-Cerrahpa & scedil;a were used in the analyses. One new fossil-species of Pinuxylon with pinoid type cross-field pits in markedly different sizes, including very large and small pits, was described as Pinuxylon anatolica Akkemik & Mantzouka sp. nov. Furthermore, Pinuxylon diversiradiatum (S & uuml;ss & Velitzelos, 2010) Mantzouka & Akkemik, 2022 and Pinuxylon ventricosuradiatum (S & uuml;ss & Velitzelos, 2010) Mantzouka & Akkemik, 2022, found in the same geological unit, were reported for the first time in T & uuml;rkiye. As to the other Early Miocene pine species, it was proposed that Lesbosoxylon kemaliyensis Akkemik & Mantzouka should be transferred to Pinuxylon kemaliyensis (Akkemik & Mantzouka 2020) Akkemik & Mantzouka 2024 as the result of this study. In conclusion, the fossil-genus Pinuxylon had a wide distribution throughout the Aegean Basin and Anatolia with a total of seven species. The five modern species of Pinus L. in T & uuml;rkiye were different than the fossil Miocene species, except for Pinus pinea L., and cover about 12 million hectares through T & uuml;rkiye. It is believed that pine trees were the main conifer species in terms of area covered through the Cenozoic of T & uuml;rkiye.
