Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Bisconti et al. 2022 | Archaebalaenoptera eusebioi differs from A. castriarquati in having convex and rounded lateral bor- ders of the maxilla, concave glenoid fossa of the squamosal, postglenoid process of the squamosal projec- ting ventrally, and lack of the interorbital region of the frontal between the posteromedial borders of the nasal bones. Archaebalaenoptera eusebioi differs from A. liesselensis in having a wider anterior border of the supraoccipital, a wider interorbital region of the frontal surrounding the posterior borders of the ascending proc- esses of the maxillae, and in having a reduced antero- posterior diameter of the interorbital region of the frontal between the nasofrontal suture and the interparie- tal bone. Archaebalaenoptera eusebioi differs from all the other Archaebalaenoptera species in that the premaxilla terminates posteriorly at a point anterior to the anterior border of the nasal. |
