Abstract: The silicified wood samples identified in Kabakça (Çatalca) and its surroundings have been found in the west of İstanbul Province. They come from terrestrial clastic sediments of the Late Oligocene-Early Miocene İstanbul Formation. Six silicified wood samples were collected and sectioned in transverse, tangential, and radial planes. As a result, five angiosperm taxa were identified. Three out of six fossil wood samples belong to Lauraceae (Cryptocaryoxylon istanbulensis Akkemik and Üner sp. nov., Lau-rinoxylon ehrendorferi Berger, 1953), and the others to Fabaceae (Dichrostachyoxylon zirkelii (Felix) Müller-Stoll and Mädel 1967), Ulmaceae (Zelkovoxylon crystalliferum Akkemik 2021), and Fagaceae (Quercoxylon mixtum Petrescu 1978). This floral compositionsuggests that these species lived in riparian and lowland well-drained areas under warm climatic conditions in the Late Oligocene-Early Miocene. In addition, slightly visible tree ring boundaries may indicate that seasonality was not strong during the lifetime of the identified trees.
