Taxonomy
Caolodelphis milleri was named by Godfrey and Lambert (2023). Its type specimen is CMM-V-8949, a partial skull (par- tial skull preserving most of the neurocranium from the supraor- bital region to the occipital condyles. The rostrum, periotics, and tympanic bullae were n), and it is a 3D body fossil. Its type locality is Popes Creek south, Zone 2-3b, which is in a Burdigalian estuary/bay sandstone in the Calvert Formation of Maryland. It is the type species of Caolodelphis.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. J. Godfrey and O. Lambert 2023 | Medium-size odontocete with the following unique combination of characters: postorbital width of skull approximately 230 mm; flattened frontals on the vertex; left and right frontals on the vertex separated from one another (possibly exaggerated to some extent by taphonomic processes); anterior end of the zygomatic processes drawn out into a pointed spur; and the basioccipital crests being greatly thickened transversely (the latter two probably represent auta- pomorphic features). This new odontocete further diers from most other clades of odontocetes except Eoplatanista, eurhino- delphinids, squaloziphiids, and members of the Chilcacetus clade in the anteroposteriorly thick postglenoid process, from Platani- delphidi in the posterior dorsal infraorbital foramen being lo- cated lateral to the lateral margin of the premaxilla, and from eurhinodelphinids in the occipital shield projecting farther an- teriorly and the temporal fossa being dorsoventrally higher and more broadly open posterodorsally. The maximum width of the skull (i.e., the bizygomatic width) is less than in Chilcacetus ca- virhinus, much less than in Macrodelphinus kelloggi, and greater than in “Argyrocetus” joaquinensis and Eoplatanista spp. |
