Mammalia - Rodentia - Muridae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|M. Freudenthal 1976||Considering its upper M1 M. parva could be considered as a large Stephanomys. The lower molars are not like those of Stephanomys. They resemble a common murid like Parapodemus, though some alterations are definitely recognizable. m1 is made up of three crests plus an anterior cusp that may be simple or split (level 3 1/2 to 4 as defined in the chapter on quantified morphology). A mesolophid is often present between the posterior two crests. The anterior cusp may be connected to the next crest by one longitudinal ridge, or by two such ridges separated by a small funnel. M3 consists of three ridges: t1, t4-5, and t7-9 (see Thaler, 1966, p. 116). In some cases t7-t9 shows a shallow sinus in the lingual wall, that indicates the possibility of a further subdivision. The teeth are moderately hypsodont. The vertical enamel plate on the labial side of the molars is hardly present. m1 has two roots, M3 has two or three roots.|
