Microcetus is a genus of extinct odontocete from the late Oligocene (Chattian) of Nordrhein-Westfalen, Germany.

Taxonomy

The type species of Microcetus, M. ambiguus, was originally described as a new species of Phoca on the basis of teeth from late Oligocene deposits in northwestern Germany.[1] The odontocete nature of the teeth was eventually recognized, and it was eventually assigned to Squalodon,[2][3] before being made the type species of a new genus, Microcetus.[4]
