Diagnosis
ReferenceDiagnosis
M. Freudenthal 1976 (Microtia)Genus of Muridae with well-develoed m1 and M3. m1 consists of a posterior part of four cusps (two crests), as present in all murids, and an anterior part that may vary in its number of crests. The maximum number of crests so far found in a Microtia m1 is seven. M3 consists of two anterior crests in V-shape, plus a varying number of crests behind this V. The total number of crest in m1 and M3 is more or less equal within each population. The labial wall of m1 and M3 is often formed by a thin vertical enamel plate that tends to form a continuous connection between the crests. This plate is best developed in very hypsodont molars with a large number of crests. In hypsodont forms the roots may be formed long after the molar has begun to wear down.
