Diagnosis
ReferenceDiagnosis
M. R. Dawson 2001Small- to medium-sized ischyromyid rodents; dental formula 1/1, 0/0, 2/1, 3/3. Lower molars have well-developed anterior cingulum; at least in early wear stages, anterior cingulum is separated by a buccal groove from the protoconid; buccal end of anterior cingulum may be cuspate; trigonid short anteroposteriorly with small trigonid basin; tendency toward strong transverse component in lophids of
lower molars, with metalophid and hypolophid from short to complete; mesoconid rounded; entoconid separated by groove from posterolophid. Upper molars have distinct hypocone; protoloph and metaloph directed toward protocone. Occlusal pattern on lower molars varies from
simple (Microparamys) to complicated by numerous small folds and crenulations (Lophiparamys, Mattimys).
