Diagnosis
ReferenceDiagnosis
R. L. Wilson 1968small cricetid (table 18) with medial anteroconid and moderate alternation of metaconid and protoconid on m1; a relatively
small round metaconid attaches low to the medial mure by a thin ridge, being nearly isolated from the protoconid; m2 with small anteroconid and mesolophid; m2 as wide as m1 ; lower molars with long oval roots, the posterior root of m1 nearly as wide as transverse diameter of the tooth.
