While underrepresented in specimen numbers, the high number of Artiodactyla species indicates a rich food supply, which in turn gave rise to a comparably massive variety of Carnivora and Creodonta. Ephemeral water bodies are indicated by the herpetofauna, particularly by pelobatid frogs, which prefer open landscapes and are adapted to dry habitats (B me 2007). Throughout the late Rupelian, modifications in palaeoenvironments are reflected inside the biosubzonation. While the general diversity of Cricetidaeincreases, their body size decreases; the dental microwear analysis of Eucricetodon jilantaiensis from Ulantatal indicates a diet plan with no fruit and improved consumption of abrasive and fibrous plants (Gomes Rodrigues et al. 2012).

No magnetostratigraphic or radiometric dating is accessible for the sections containing this biozone. As a result, the proposed correlation is preliminary.Palaeobio Palaeoenv (2017) 97:219?Correlation: corresponds to Zone D of H k et al. (1999). Subdivision: none.Discussion In all statistical analyses, the grouping in the samples follows their assignment to biozones. This documents that every single biozone is characterised by a distinct faunal kind, reflecting a much more or much less uniform evolutionary degree of the different taxa and comparable ecological conditions. Determined by the results of your PCA and NJA, we recognize a significant split in between Rupelian faunas with the Cricetops dormitor Zone and these in the subsequent Chattian Amphechinus taatsiingolensis and Amphechinus key zones. The position of your Chattian samples within the scatter plots (Fig. 1) indicates a gradual improvement of these biozones. The samples from the Aquitanian Tachyoryctoides kokonorensis Zone comply with this all round (stratigraphic) trend but are much more separated, indicating a different turnover at the Oligocene/Miocene boundary. These punctuations are most in all probability the result of climate forcing and corresponding adjustments in palaeoenvironments (Harzhauser et al. 2016). A detailed reconstruction with the palaeoenvironments is beyond the scope of this paper, but some common conclusions could be drawn: Rupelian (Cricetops dormitor Taxon Range Zone): the higher diversities and equivalent contributions by Palaeolagidae, Dipodidae, Cricetidae and Erinacidae (Fig. 4) recommend diverse habitats with various ecological niches. Most small mammals were ground dwellers, partly adapted to a fossorial lifestyle (e.g. Tsaganomyidae, Wessels et al. 2014). Superb discoveries of partly articulated skeletons in fossil burrows give a particularly poignant example (Daxner-H k et al. 2017, this problem). Substantial Cricetidae, like Eucricetodon asiaticus and E. caducus, are popular. The teeth of these species have brachydont/bunodont crowns, oblique/blunt cusps, a uncomplicated occlusal pattern and low crown heights, indicating a eating plan with an omnivorous component (Williams and Kay 2001; Samuels 2009). Similarly, dental microwear analysis of E. asiaticus from Ulantatal (Gomes Rodrigues et al. 2012) indicates that its diet plan incorporated a mixture of fruits and grasses using a element of animal matter.
