Diagnosis
ReferenceDiagnosis
C. W. Hibbard 1953Cimarronomys is a cricetine rodent with a large mental foramen located near the dorsal surface of the diastemal region anterior
to m2. The teeth are short-crowned. The anteroconid of m1
has a deep anteromedian groove, and the anterolingual vaIley is broad,
widely separating tbe anterolingual conulid (Hooper, 1952) of the
anteroconid from tbe metaconid. m2 is not reduced. It has two
internal reëntrant vaIleys. The posterointernal valley of m3 is shallow; with wear it forms an isolated enamel pit which later disappears. The external cingulum is weIl developed on aIl molars, closing off the reëntrant valleys between the cusps and forming basins. The name Cimarronomys id formed from Cimarron, for the Cimarron River,combined with -omys.
