Diagnosis
ReferenceDiagnosis
S. L. Donohue et al. 2013Differing from Mesodma thompsoni in: larger p4 with greater number of serrations (16), arcuate mesial face (larger L2:L ratio). Differing from Cimolodon nitidus and Anconodon gidleyi in: large p4 (L = 7.00 mm) with greater number of serrations, gently sloping, rounded mesial face (smaller L2:L ratio), lower crown (smaller H:L ratio), and a smaller mesiobuccal lobe. Differing from C. similis and C. foxi in: larger p4 with greater number of serrations, lower crown (smaller H:L ratio). Differing from Meniscoessus robustus and M. seminoensis in: p4 with rounded, muted serrations, greater number of serrations, arcuate mesial face (larger L2:L ratio), lack of a notched first serration, and overall less robust crown.
