Özet

Many different Cupressaceae species were described from the early Miocene of Turkey. Particularly, Glyp-tostroboxylon Conventz, 1885 and Taxodioxylon Hartig, 1848 from Cupressaceae are the most common genera. With the present study, a new fossil Juniperoxylon (Houlbert, 1910) Kräusel, 1949 species from early Miocene of north-western Turkey was described as Juniperoxylon acarcae Akkemik sp. nov. The new species has diffuse and zonate axial parenchyma, 2-3 (5) cupressoid pits per cross-field, sometimes presence of crassulae, uniseriate to biseriate, op-posite, frequent, contiguous and sometimes spaced radial wall pits, even uniseriate and irregularly or alternately bise-riate pits on tangential walls, horizontal walls of rays smooth and/or pitted, ray width uniseriate and rarely partly bise-riate, and end walls of axial parenchyma nodular and smooth. The new species is the first Juniperoxylon species de-scription from Turkey. According to the vegetation units (VU), this fossil species may indicate the forest was likely well-drained lowland and/or upland conifer forest (VU7).
