摘要: In this paper, a new species of Vasseuromys, V. bergasensis sp. nov., from the locality Bergasa (Ebro Basin, Spain), is described. contains fauna belonging to Late Oligocene (zone MP30), composed—among other species—of Issiodoromys pseudanaema and Rhodanomys transiens. The main diagnostic features nov. are presence long centrolophid (fused or not mesoconid) in lower molars, large reduction number length extra ridges upper absence between metalophid mesolophid, metatrope more than half specimens teeth M1 M2. similar size elegans smaller members genus. age simple dental pattern Vasseuromys allow us hypothesize about relationships within
