The distribution of fossil taxa in the strata shows a major turnover event within the late Miocene, at a time slightly preceding the sedimentological change represented by the boundary between the Bahe and Lantian Formations (ca. 7Ma). The mammal fauna postdating the change shows a strong resemblance to the classic Baodean mammal faunas of North China. Based on this turnover event a resurrection of the Bahean Land Mammal Age, predating the Baodean LMA within the late Miocene, would be possible. The Bahean/Baodean turnover event was ecological as well as taxonomic and suggests significant climatic change at this time, possibly driven by onset or intensification of the East Asian summer monsoon circulation system.

These sub‐basins mainly comprise a stratigraphically discontinuous and laterally variable series, represented by ‘fluvio‐lacustrine’ siliciclastic and carbonate sediments deposited over a wide range of environments, including meandering and braided rivers, coastal fluvial and fan deltas, mixed carbonate‐siliciclastic shores, dry lake flats, and coal‐bearing swamps. In the Ereğli‐Ulukışla Basin, higher palaeotopographic conditions existed in the AT because of the uplift of the Central Anatolian Plateau during late Middle Miocene (Serravallian)‐early Late Miocene (Tortonian) and the subsequent uplift of the Taurus Mountains in the latest Miocene (Messinian) as deduced in the Tepeköy region (northeast) of the HT sub‐basin....
