Ray-Finned Fish Remains from the Vyatkian (Upper Permian) of the Nizhny Novgorod Region
Аннотация
Permian ray-finned fishes from Nizhny Novgorod Region (Russia) are represented by teeth and scales of Toyemia blumentalis, Isadia aristoviensis, I. suchonensis, I. arefievi, I. sp., Mutovinia stella, Geryonichthys longus, Varialepis vitalii, Strelnia sp., Elonichthyidae gen. indet., and Discordichthyidae gen. indet. Most species are distributed throughout the Vyatkian Stage and occur in other regions of the European Russia. The occurrence of Isadia arefievi in Sartakovo and Lagerny Ovrag-1, -3 indicates the Upper Vyatkian (Nefedovian and/or Zhukovian) age of these localities. The fauna of ray-finned fishes from the Vyatkian deposits of the Nizhny Novgorod Region is most similar to the synchronous but better- known fauna of the Vladimir Region.
