“…According to the suggested evolutionary scenario, these species originated from population of P. latidens. P. hansi clade, originated from the same ancestral stock, led to the widely distributed Late Turolian P. abbreviatus, which, in its turn, splits during Ruscinian into two geographic lineages: a West Asian one represented by P. hansi and its possible descendant P. tchaltaensis and an East Asian one that led to P. complicidens [10].

“…deli gerbil with its "cricetid" structure of cusp/cuspid alternation on m1/M1 and the presence of two labial and one lingual sinusids on m2 clearly shows the characteristic features of Pseudomeriones. Historical overviews of the genus are given by [2][3][4][5][6][7][8][9][10].…”

“…China from Anatolia and evolved firstly into P. abbreviatus [14,15] which [4], evolved into P. complicidens later in China [20]. In Anatolia, P. latidens must have evolved into P. rhodius [16] and P. megistos [10] through P. pythagorasi [17] and into P. tchaltaensis through P. abbreviatus and then P. hansi [10] (Fig. 2).…”

Pseudomeriones hansi nov. sp. is described from deli locality (SW Sivas, Central Anatolia). The morphological description of the new species is given within its own systematic and stratigraphic relationships. The micromammalian fauna of deli gives evidence for a new species which is characterized by its small size, its M2 with a deep lingual sinus curved backward and its m1 with a symmetric triangular anteroconid that bears a moderate labial arm reaching the base of the protoconid.

“…Pseudomeriones, a genus already present in Asia since the Vallesian and also in the Greek South Aegean Island Samos during the middle Turolian, seems to enter the area of northern Greece during the Messinian salinity crisis (Sylvestrou and Kostopoulos 2007). It appears with two species in the faunas correlated with the last part of the Turolian and with at least one in the transitional faunas.…”

“…Just above the levels with the mammal remains, there are sand beds that include more than 80 % volcanic clasts from the Almopia volcanic centre (northern Greece), the first activities of which have been radiometrically dated from 5.60±0.10 to 5.05±0.14 Ma (Vougioukalakis 2002;Sylvestrou and Kostopoulos 2007). The presence of a derived large-sized Pseudomeriones species in PLM-B suggests that the fauna was accumulated during the last part of the Turolian, more specifically during the Messinian Salinity Crisis.…”

Even though there are numerous late Miocene mammal localities in the southern Balkans, those of late Turolian and early Ruscinian age are uncommon. Using the available data, mainly from Greece and Bulgaria, we compiled information about the faunal and palaeoenvironmental changes at the Miocene/Pliocene boundary. The analysis of the faunal elements indicates that several Miocene taxa disappeared, whereas new taxa appeared. The faunal composition of the mammal zones suggests a decrease of the bovids and giraffids and an increase of cervids and suids from MN 12 to MN 14. The available faunal assemblages from zones MN 12-MN 14 are compared with a set of modern and fossil assemblages from known environments to determine their palaeoenvironment.The results indicate an increase of the closed character of the environment from MN 12 to MN 14, suggesting a gradual increase of the humidity and the development of more forestial conditions. The rodent faunas from northern Greece ranging from MN 13 to MN 14 show a characteristic aridification of the biotopes and the introduction of African elements in the last part of the MN 13 (during the Messinian Salinity Crisis), with a subsequent return of humid-and/or-forested biotopes towards the MN 13/14 boundary. The faunal and sedimentological data for the Greek localities correlated with the Turolian/ Ruscinian boundary suggests a general open landscape with several water spots of variable sizes surrounded by dense forests.

Although the existence of fossil turtles in Makrygialos and the surrounding areas, on the west side of the Thermaikos Gulf in Northern Greece, has been known for almost two decades, it has not been studied so far in detail. Over the last 5 years, we have conducted systematic fieldwork and exploration, focusing on the discovery and recovery of fossils in the coastal broader area of Makrygialos. Eleven turtle specimens have been found so far, eight of which have been collected, on the outcrops of the beaches of Makrygialos and Agiannis. Their age is estimated between the latest Miocene and Pliocene. Four of these specimens are terrestrial giant tortoises, two of them are small tortoises which we identify as the species Chersine hermanni sensu lato, and the last two are freshwater turtles which we attribute to the genus Mauremys sensu lato. Here, we present our studies on the small‐sized turtle species from this region. The fossil turtle fauna of Makrygialos is among the richest and most diverse in Greece, as in only a few other Greek localities at least three species of fossil turtles have been found. The C. hermanni specimens found in Makrygialos are probably the oldest fossils of the species found in Europe. The small‐turtle faunal composition during the Neogene along the east and west sides of the Thermaikos Gulf was completely different.
