Analysis of zoogeographic, paleogeographic, and molecular data has shown that the ancestors many fresh- brackish-water cold-tolerant hydrobionts Mediterranean region Danube River basin likely originated in East Asia or Central Asia. The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, Schizothorax are examples these groups among vertebrates, Magnibursatus (Trematoda), Margaritifera, Pot...

The Dacian Basin was uniquely situated to record late Miocene hydrological changes that influenced depositional environments and faunal dispersal patterns in Central Eurasia's mega-lake Paratethys. Differences between the high strontium isotope ratio (87Sr/86Sr) of waters from Lake Pannon local Carpathian rivers low 87Sr/86Sr Eastern Paratethys (Black Sea ‒ Caspian Sea) allow a thorough investi...

Reconstructing fossil bony fish faunas using otoliths is a well-established method that allows diverse and dense record in time space to be assembled. Here we report about rich otolith-based fauna from the middle Sarmatian s.l. (middle Bessarabian) Jurkine, Kerch Peninsula, Crimea. The study based on more than 5,000 specimens constituting 36 different species, 24 of which are new 2 remain open ...
