Restudy of the Late Oligocene dormice from northern Junggar Basin

A new glirid genus and species, Gliruloides zhoui, is named based on specimens from the Late Oligocene Tieersihabahe Mammal Assemblage Zone I （Tie-I zone） of the northern Junggar Basin, Xinjiang. The new genus is diagnosed by the following features： middle-sized dormouse; occlusal surface of cheek teeth concave; upper and lower cheek teeth dominantly with nine transverse ridges; the anterotrope（id） and posterotrope（id） well developed and extending almost full length of corresponding valleys; transverse ridges of upper cheek teeth usually free-ended labially; M1/2 with V- or narrow U-shaped trigon; the precentroloph not connected to the endoloph that is incomplete or nearly complete; the endolophid in lower cheek teeth discontinuous or continuous; labial end of the anterolophid curving slightly distally but not connected with the protoconid; root number of p4, ml-3, P4 and M1-3 being 2, 2, 3 and 3 respectively. We discuss the differences of Gliruloides from Glirulus and Vasseuromys and assign the Anatolian Vas
