Cetotheriinae
Taxonomy
Cetotheriinae was named by Whitmore and Barnes (2008) [Whitmore and Barnes (2008) did not first name the subfamily Cetotheriinae, but they were the first to use it as a subfamily of Cetotheriidae].
It was assigned to Cetotheriidae by Whitmore and Kaltenbach (2008), Whitmore and Barnes (2008), Tarasenko and Lopatin (2012), Tarasenko (2014), Goldin and Startsev (2017).
It was assigned to Cetotheriidae by Whitmore and Kaltenbach (2008), Whitmore and Barnes (2008), Tarasenko and Lopatin (2012), Tarasenko (2014), Goldin and Startsev (2017).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. Goldin and D. Startsev 2017 | Cetotheriids more closely related to Cetotherium than to Herpetocetus, and sharing the following synapomorphies: an anteroposteriorly long and dorsoven- trally high zygomatic process of the squamosal (also shared by Joumocetus and Otradnocetus) and apertures for the vestibular and cochlear aqueducts in a common deep recess on the periotic. Differ from Herpetocetinae in a proximal end of the premaxilla exposed on the skull surface in dorsal view, a transversely wide postglenoid process, an occipital shield extending to the level of the centre of temporal fossa or anterior to it, a high and moderately long posterior pro- cess of the tympanoperiotic with the slightly convex (rather than extremely short and ‘plug-like’) lateral surface exposed on the posterolateral wall of the skull, and a mandible with a high condyle and a short angular process. Most of mem- bers of Cetotheriinae show intensive pachyosteosclerosis of postcranial skeleton, and some of them also have pachyo- stotic mandibles. |
