Diagnosis
ReferenceDiagnosis
C. M. Peredo et al. 2018Maiabalaena nesbittae is diagnosed by the following combination of character states: frontal-parietal sutures that converge posteriorly with the frontals penetrating between the parietals; apex of the occipital shield represents the dorsally highest part of the cranium; supramastoid crest extending past the posterior margin of the temporal fossa but not to the distal tip of the zygomatic process; length of the squamosal fossa is less than three-fourths the length of the temporal fossa; triangular coronoid process of the mandible that is anteroposteriorly longer than it is dorsoventrally tall; and a spear shaped distal mandib- ular terminus in lateral view.
