Mesokentriodon is an extinct genus of kentriodontid toothed whale known from the Middle Miocene (Langhian–Serravallian ages) Pisco Formation of Peru.[1]
Etymology
In 2026, Olivier Lambert and colleagues named Mesokentriodon protohumboldti as a new genus and species of kentriodontid odontocete (toothed whale) based on two autapomorphies (unique characteristics): a rostrum which was moderately elongated, and 40 teeth in the upper row.[1]
The generic name Mesokentriodon derives from the Ancient Greek meso-, meaning intermediate, and the genus Kentriodon. The specific epithet of the type species, M. protohumboldti, contains the prefix proto-, meaning first or before, and references the Humboldt Current in the latter part.[1]
