“…The precipitation decrease probably resulted from extended drier seasons and a more distinct seasonal precipitation, which coincides with data from the vegetation reconstructions. Mammal and paleobotanical proxies give precipitation estimates that are similar on the regional scale (Akgün et al, 2007;Strömberg et al, 2007;Eronen et al, 2011;Kayseri-Özer et al, 2014) and support the above conclusions.…”

“…Remarks : Pinus subgenus Pinus ( Diploxylon ) pollen type is characterized by narrowly attached and nearly spherical sacci (Hesse et al ., ). Similar diploxylon‐type pollen has previously been reported from various middle Miocene localities of western Turkey: Pinus silvestris Group (= sylvestris type) (Benda, ; Kayseri‐Özer et al ., ; Bozcu et al ., ), Pityosporites spp. (Ediger, ; figs 4.6–7), P. labacus [= Pinus labacus (R.Potonié) Raatz ex R.Potonié] (Akyol & Akgün, ; Takahashi & Jux, ; Akgün & Akyol, ; Akgün et al ., ; Kayseri‐Özer et al ., ), Pinus diploxylon ‐type (Akkiraz, ; Akkiraz et al ., ).…”

“…Palaeobotanical investigations of early and middle Miocene fossil‐bearing strata in western Anatolia predominantly concentrated on pollen stratigraphic correlation (e.g. Benda, ,b; Akgün & Akyol, ; Akgün, Kayseri & Akkiraz, ) and various aspects of the climatic and palaeoenvironmental development of the region using palynological data (Akgün et al ., ; Ediger, ; Gemici, Akyol & Akgün, ; Gemici et al .,, ; Kayseri‐Özer et al ., ; Kayseri‐Özer, Sözbilir & Akgün, ; Takahashi & Jux, ; Yavuz‐Işık, ; Yavuz‐Işık et al ., ) and, rarely, evidence from macrofossils (Engelhardt, ; Mädler & Steffens, ; Gemici et al ., , , ). All previous studies of dispersed Neogene pollen and spores in Turkey have been based on light microscopy.…”

The middle Miocene palynoflora and palaeoenvironments of Eskihisar (Yatağan basin, south-western Anatolia): a combined LM and SEM investigation

et al. 2016

We investigated a palynological section from middle Miocene sediments at Eskihisar (south‐western Anatolia) to establish biogeographic links of the palynoflora and to infer the palaeoenvironment. Four algal palynomorphs, nine spore taxa, eight gymnosperms, three monocots and 67 dicot pollen types were encountered and investigated using the ‘single grain method’ that combines light microscopy and scanning electron microscopy. Two pollen zones reflect different phases of basin development. Zonal vegetation remained fairly stable across the section and reflects heterogeneous environments including broad‐leaved deciduous forest, subtropical forest and sclerophyllous and semi‐evergreen oak forest. Conifers were accessory elements in the broad‐leaved deciduous forest communities and replaced these at higher elevations. Some herbaceous taxa (Plumbaginaceae) indicate scattered occurrences of sandy and/or rocky soils. Biogeographic affinities are general Northern Hemisphere, North American and East Asian, as also suggested by the macrofossil record. Only two taxa provide potential biogeographic links with the African flora. This suggests that biome shifts of plant taxa between African subtropical/tropical biomes and Anatolian (western Eurasian) temperate forests and shrublands may have been rare in the middle Miocene.

Early Miocene micropalaeontological record of the Aspiras Basin (Kastamonu), north‐west Anatolia, Turkey

This study presents the micropalaeontological data (palynomorphs and ostracods) including index taxa to assign a precise age, and the palaeoecological evolution of the Aspiras Basin, south‐east Kastamonu, northern Anatolia. The succession may informally be divided into a lower part including rich lignites interbedded with fine‐grained sediments and an upper part which comprises lignite‐free deposits such as mudrocks with dense gypsum and rare limestones. The sediments of the lower part were deposited in a wetland (i.e. peat‐forming environment) showing oscillations of the lake level, whereas the upper part indicates the shoaling or closing phase of the lake. Early Miocene age is assigned to the Aspiras Basin due to the presence of index taxa such as Leiotriletes maximus, Dicolpopollis kockelii, Intratriporopollenites instructus, Caryapollenites simplex, and ostracods Pseudocandona praecox and Potamocypris gracilis. Moreover, a new species of ostracod, Heterocypris aspirasensis, has been discovered. In the lowermost part of the succession, palynomorph spectra are dominated by spores such as Leiotriletes maxoides, L. maximus, and Verrutacosporites alienus while diverse pollen types, notably conifer pollen, attain high abundances further up in the succession. In the forested environment, the mixed mesophytic plants were less diverse. Low quantities of herbaceous taxa such as Ephedra sp., Poaceae, Amaranthaceae, Asteraceae‐Asteroideae, and Asteraceae‐Cichorioideae indicate the limited occurrence of open areas. During the Early Miocene, a warm and moist climate prevailed according to quantitative palaeoclimate data and the presence of the mega‐mesothermic taxa such as Taxodioideae, Mastixiaceae, Engelhardia, Sapotaceae, and Calamus.
