Какие ископаемые амфибии найдены на территории Кавказа? Особенно интересуют темноспондилы и антракозавры.

На Кавказе судя по всему было куча амфибий. Но мне о них пока ничего толкового не известно. Знаю точно, что в этом регионе обитали лепоспондилы.

Когда на Кавказе было много амфибий (я имею в виду период)?

Не знаю, меня самого это интересует. По идее на Кавказе должно быть куча ископаемых амфибий. Климат тут был благоприятный для них, а Кавказ в древности представлял из себя, как я уже не единожды говорил, ряд островов. Тут и синапсид и птерозавров должно было хватать.

Proteids (Proteidae) are a family of specialized, paedomorphic, perennibranchiate salamanders with an
elongate body. Extant proteids are confined to Europe and North America, but in the past the family’s range
extended as far eastwards as Kazakhstan or, possible, Kirghisia. The fossil record for the Proteidae is limited (Estes,
1981), particularly from the territory of the former Soviet Union. Badly preserved vertebrae of Proteidae? were
reported from the lower Eocene Andarak II locality in Kirghisia (×õèêâàäçå, 1984). The middle Miocene (middle
Sarmatian, Vallesian) Mioproteus caucasicus Estes, Darevsky, 1977 was described on the basis of isolated vertebrae
and some cranial elements from the Maikop locality in the North Caucasus, Russia (Estes, Darevsky, 1977).
Mioproteus sp. was reported from the Miocene Kentyubek locality in western Kazakhstan (Áåíäóêèäçå, ×õèêâàäçå,
1976; ×õèêâàäçå, 1984; Estes, 1981). Chkhikvadze (×õèêâàäçå, 1981: 152) stated that “probably all the salamander
amphicoelous vertebrae from the [Mio-Pliocene Moldavian and Ukrainian] localities Buzhory, Male,
Novoelisavetovka, Novaya Emetovka, Cherevichnoe, and Kuchurgan should be referred to the genus Mioproteus.”
These records were repeated in Chkhikvadze (×õèêâàäçå, 1984) and Chkhikvadze & Lungu (×õèêâàäçå, Ëóíãó,
1984), who referred a fragmentary vertebra from the middle Sarmatian (Vallesian, MN 9) Moldavian Buzhory
locality to Mioproteus sp. However, amphicoelous vertebrae are also characteristic for many salamander families,
including the Cryptobranchidae and Hynobiidae, both of which are also known from the Neogene of Eurasia
(Roček, 1994; Averianov, Tjutkova, 1995; Venczel 1999). For example, the cryptobranchid Andrias [sp.] was
reported from the Ruscinian (MN 14) Kuchurgan locality in Moldavia (×õèêâàäçå, 1981, 1984) and some Miocene
localities in Moldavia (×õèêâàäçå, 1984). The ZIN PH collection contains an undescribed dentary fragment of a
cryptobranchid from the lower Ruscinian (MN 14) Antipovka locality, Voronezh Region of Russia. None of the
vertebrae from the localities mentioned by Chkhikvadze has been described or illustrated and their attribution to
proteid salamanders remains to be demonstrated; these records are not considered future here. The only reliable,
published records of fossil European Proteidae are the following: M. caucasicus from the middle Miocene of Maikop,
western Russia and Appertshofen, Germany; Orthophyia longa Meyer, 1845 from the upper Miocene of Oeningen,
Germany; “Mioproteus” wezei (Estes in Młynarski et al. 1984) from the lower Pliocene of Węże II, Poland and upper
Pliocene of Balaruc II, France; and Proteus bavaricus Brunner, 1956 from the Pleistocene of Kleinen
