The fossil fallow deer Dama geiselana (Cervidae, Mammalia, upgrade to species level) in the context of migration and local extinctions of fallow deer in the Late and Middle Pleistocene in Europe

摘要

The fossil fallow deer Dama dama geiselana Pfeiffer from Neumark-Nord (Saxony-Anhalt, Germany) is upgraded to species level and discussed within the current taxonomy of recent and fossil fallow deer. Typical antler and skeletal characteristics are discussed in comparison with the recent Dama dama, Dama mesopotamica and the fossil species Dama clactoniana, Dama nestii and Dama rhenana. The phylogenetic relationship of fallow deer can be traced back to the Late Pliocene and distinguished morphologically from Cervus elaphus, Cervus nippon and Axis axis. Late and Middle Pleistocene finds from Germany are presented and discussed in the context of the finds from the Mediterranean region and Great Britain. The differences in antler morphology and bone dimensions in West German and North-East German fallow deer from the Late Pleistocene support the hypothesis of different immigration channels, on the one hand from the eastern Mediterranean along the Danube and on the other from the west along the Rhone and Rhine. In the Middle Pleistocene, Dama mesopotamica is considered as the typical fallow deer in the eastern Mediterranean, while in the west, Dama clactoniana is widespread. The hypothesis of immigration from the eastern Mediterranean is supported by the fossil record in Germany with the fallow deer from Edesheim. Conversely, Dama geiselana probably influenced East Mediterranean populations. Special tooth characteristics of Dama geiselana occur with lower frequency in Dama mesopotamica. In the Bronze Age, the fallow deer from Kastanas (Macedonia) shares antler characteristics, the high frequency of specific features of the scapula, and the astragalus with Dama geiselana. A relict population of Dama geiselana probably reached the Eastern Mediterranean at the beginning of the last cold stage.
