Redescription and phylogenetic relationships of Spermophilus citelloides (Rodentia: Sciuridae: Xerinae), a ground squirrel from the Middle Pleistocene – Holocene of Central Europe

Spermophilus citelloides is a poorly known Old World ground squirrel from the Middle Pleistocene – early Holocene of Central Europe that has only been briefly described previously. Here, we expand our understanding of its craniodental morphology by providing the first detailed description of numerous S. citelloides materials from five Late Pleistocene and early Holocene localities of Hungary and Slovakia. Spermophilus citelloides is recognised...
