The foundation bloodstock of the Aneberg-Nordkirchen were Lithuanian mares crossed on Dülmen Pony stallions.

Other breeds sometimes alleged to be surviving Tarpans include the Exmoor Pony and the Dülmen Pony.

Between the two world wars, the German brothers Heinz and Lutz Heck crossed Koniks with other breeds, such as the Dülmen Pony, Gotland Pony, Icelandic Horse and the Przewalski's Horse, in order to create a breed resembling their understanding of the Tarpan phenotype.
