The general view is that there was only one subspecies, the tarpan, "Equus ferus ferus". In recent centuries, two subspecies, the quagga and the tarpan, became extinct. The Hecks believed they could recreate the extinct tarpan subspecies by back breeding living descendants. Restored in 2007 at the expense of the family of Ruslan Tarpan, Odessa businessman. They were known to be located near the head of Doolin Run near Tarpan Ridge. The Hucul bears some resemblance to the now-extinct Tarpan. It was mixed by David Frazer at Tarpan Studios in San Rafael. Mahalaya marks the end of the fortnight-long Tarpan to the ancestors. The last captive tarpan died in 1909 in a Russian zoo. Tarpan 239D had a diesel engine. The last tarpan was caught near Kherson in 1866. The human-caused extinction of the tarpan began in Southern Europe, possibly in antiquity. Therefore, the European tarpan may have contributed to the domestic horse. The modern Konik horse resembles the extinct Tarpan however.
