The taxonomic composition of a recently discovered silicified fossil forest, preserved by volcanic activity 18.2-16.9 million years ago in Çamlıdere near Ankara (Turkey), is investigated. Many samples collected were divided into 2 groups as CAM1 and CAM2. Thin sections from transversal, radial, and tangential directions were cut to identify the woods. Wood identifications were performed using standard techniques and fossil wood features. The preserved wood indicates that the forest was composed almost exclusively of Taxodium (CAM1) and Sequoia (CAM2). These genera were extinct from Anatolia and Europe during late Miocene.

A paleopalynological study was performed on the fossilized pollen found in the coal and clay layers of the Akçelik Coalmine, which is one of the open lignite quarries located at the northern part of İstanbul, and 15 genera belonging to 14 families were identified from the late Oligocene of İstanbul. Of these 14 families, 4 families belong to Gymnospermae, and 10 of them belong to Angiospermae. In the study, 85.8% of pollen is arboreal (AP) (woody plants), 10.4% is non-arboreal (NAP) (herbal plants), and rest of them (3.8%) could not be identified. The middle coal layer has a significant number …
