Diagnosis
ReferenceDiagnosis
J. X. Samuels et al. 2023Auditory bullae with ventral and lateral inflation. Mastoid with dorsal, lateral, and posterior portions inflated. Buccinator and masticator foramina fused. Distinct swelling present at posteroventral border of the infraorbital foramen (unlike other fossil and extant dipodomyines with the exception of Dipodomys). Premaxillary-maxillary suture crosses the midline of the palate 1/3rd the distance from the posterior margin of the incisive foramen (unlike other fossil and extant dipodomyines). Posterior border of the maxillary root of the zygomatic arch lies lateral to P4 and anterior to the posterior end of the nasals and premaxillae. Posterior end of the nasals extends farther posteriorly than the premaxillae (unlike other fossil and extant dipodomyines). Interparietal constricted due to auditory bulla expansion. No supraorbital bony flange present (unlike Cupidinimus and extant dipodomyines). Upper incisors lack a central groove. Premolars and molars lack chevrons (unlike other fossil and extant dipodomyines).
