Equus gmelini or Extinct Tarpan. Computer illustration and photo-reconstruction of the extinct tarpan Equus gmelini or Eurasian wild horse. Equus gmelini provided the foundation for all Eastern European types of horse. This diluvium horse existed in wild herds until the eighties of the nineteenth century and was widely spread around the Black Sea, the Caspian Sea and further east to Aral Lake. In these areas he was called tarpan. The human-caused extinction of the tarpan began in Southern Europe, possibly in antiquity.
