Diagnosis
ReferenceDiagnosis
R. Ziegler et al. 2007Smallest species of the genus with the dental formula 2-1-2-3; mental foramen below anterior root of p4 or under p2; p2 single-rooted; m1 and m2 with well-developed pre- and ectocingulids tapering under the hypoconid; m3 with distinct heel. Upper M1 and M2 without distinct metaconule, without postmetaconule crista. Palaeoscaptor tenuis differs from P. acridens in the reduced number of lower premolars and in the smaller size, from P. rectus in its distinctly smaller size.
