Importance of the mustelids from the Early Pleistocene site Schernfeld (Bavaria, Germany) on the Eurasian context.

The Early Pleistocene fossil site of Schernfeld, a karst fissure filled with an ossiferous breccia, is well known due to the abundant fossil remains, mainly of micromammals and carnivores. Since the discovery, the taxonomic status of the Schernfeld mustelids has caused controversy and, consequently, various authors have listed different species. Until recently, none of these species has been the subject of adequate studies. A detailed revision of the Schernfeld mustelids material was made through comparative morphology based on mustelids from other European Early and early Middle Pleistocene sites. It reveals the presence of five mustelids: Gulo gulo schlosseri, Martes vetus, Meles meles, Mustela palerminea, and Mustela praenivalis. Their remains are characterized by ancestral features, especially in M. vetus, M. palerminea, and M. praenivalis. Due to the morphology of mustelids and the taxonomical composition of the Schernfeld fauna, the biochronological age of the entire assemblage was re-evaluated and assessed for ca. 1.9-1.7 mya.
