“…The morphological traits described above (e.g. lack of angular fossa on the scapula and preacetabular fossa on ilium, general outline, form, and size of the scapula and ilium) as well as the bone dimensions are the same as those found in the common toad Bufo bufo (Blain, Gibert & Ferràndez-Cañadell, 2010). …”

BackgroundThe present-day amphibian and reptile fauna of Western Siberia are the least diverse of the Palaearctic Realm, as a consequence of the unfavourable climatic conditions that predominate in this region. The origin and emergence of these herpetofaunal groups are poorly understood. Aside from the better-explored European Neogene localities yielding amphibian and reptile fossil remains, the Neogene herpetofauna of Western Asia is understudied. The few available data need critical reviews and new interpretations, taking into account the more recent records of the European herpetofauna. The comparison of this previous data with that of European fossil records would provide data on palaeobiogeographic affiliations of the region as well as on the origin and emergence of the present-day fauna of Western Siberia. An overview of the earliest occurrences of certain amphibian lineages is still needed. In addition, studies that address such knowledge gaps can be useful for molecular biologists in their calibration of molecular clocks.Methods and ResultsIn this study, we considered critically reviewed available data from amphibian and reptile fauna from over 40 Western Siberian, Russian and Northeastern Kazakhstan localities, ranging from the Middle Miocene to Early Pleistocene. Herein, we provided new interpretations that arose from our assessment of the previously published and new data. More than 50 amphibians and reptile taxa were identified belonging to families Hynobiidae, Cryptobranchidae, Salamandridae, Palaeobatrachidae, Bombinatoridae, Pelobatidae, Hylidae, Bufonidae, Ranidae, Gekkonidae, Lacertidae, and Emydidae. Palaeobiogeographic analyses were performed for these groups and palaeoprecipitation values were estimated for 12 localities, using the bioclimatic analysis of herpetofaunal assemblages.ConclusionThe Neogene assemblage of Western Siberia was found to be dominated by groups of European affinities, such as Palaeobatrachidae, Bombina, Hyla, Bufo bufo, and a small part of this assemblage included Eastern Palaearctic taxa (e.g. Salamandrella, Tylototriton, Bufotes viridis). For several taxa (e.g. Mioproteus, Hyla, Bombina, Rana temporaria), the Western Siberian occurrences represented their most eastern Eurasian records. The most diverse collection of fossil remains was found in the Middle Miocene. Less diversity has been registered towards the Early Pleistocene, potentially due to the progressive cooling of the climate in the Northern Hemisphere. The results of our study showed higher-amplitude changes of precipitation development in Western Siberia from the Early Miocene to the Pliocene, than previously assumed.

“…More recently, the presence of green toads (Bufo viridis s.l.) from the Iberian late Early Pleistocene (Blain et al, 2010a) has also been reported. Here, we will review the "exotic" taxa from the last 2.6 Ma recovered on the Iberian Peninsula.…”

“…(Blain et al, 2010a). The green toad remains recovered at Cueva Victoria are by far the most numerous and diverse fossils attributed to B. viridis in Spain and comprise some 498 elements representing almost every part of the skeleton, whereas only a single ilium has been recovered in Almenara-Casablanca-3 Blain et al, 2010a), and five ilia in Barranco León (Blain et al, 2010a). New materials currently under study from the Quibas site in the region of Murcia also seem to belong to this species (Blain, personal observation).…”

“…A similar phenomenon occurs on the Iberian Peninsula, where another toad, Bufo viridis sensu lato, appears as fossils in a number of late early Pleistocene (approx. 1.1-1.4 Ma) localities in southern Spain, such as Barranco León (Granada), Almenara-Casablanca-3 (Castellón), Cueva Victoria and Quibas (Murcia) (Blain et al 2010(Blain et al , 2015Blain 2014). The early Pleistocene seems to have been an opportune time for both toads and humans to spread across Europe, perhaps thanks in part to a trans-Adriatic dispersal route.…”
