Hír, J.: A Lök-völgyi-barlang őslénytani ásatásának eredményei

Comments The presence of the large sized sousliks is sporadic in the Hungarian Pleistocene (JÁNOSS Y D. 1979, 1986). Their systematic position is not completely understood, because the low noumber material and the lack of special studies. The measurements of the finds from the Lök-völgyi Cave are very similar to those of the Citellus major from Uppony (JANOSSY D. 1979, 1986), but the morphology of the m3 molars is different. The material from Uppony is close to the recent Citellus citellus with the diagonally situated Protoconid-Metaconid axis and high developed anterior edge and weekly developed Mesostylid. In the Lök-völgyi tootcrowns the mesostylid is strongly developed and the anterior portion of the tooth is not as specialized as in the molars of Citellus citellus (Fig.9.). Cricetus sp.
