Diagnosis
ReferenceDiagnosis
R. Ziegler et al. 2007Medium-sized Amphechinus-species with well developed metaconules in most of the M1, and moderately developed metaconules in most of the M2. It is distinctly larger than A. minutissimus, and A. taatsiingolensis from the same region. It differs from A. microdus from the Early Miocene of Kazakhstan in the bigger size of m1, m3 and M2 and in the presence of metaconules on M1 and M2. It differs from A. bohlini from the Early Miocene of the Junggar Basin, China, in the longer p4, the smaller m1 and m2, in the bigger m3 and in the more anterior position of the mental foramen. All the other Amphechinus species from North America, Europe, Africa and Asia cannot be confused, because they are much bigger.
