Microcetus
''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.〔H. Meyer. 1840. Phoca ambiguua, Munster. Beitrage zur Petrefacten-Kunde 3:1-11〕 The odontocete nature of the teeth was eventually recognized, and it was eventually assigned to ''Squalodon'',〔E. L. Trouessart. 1898. Catalogus mammalium tam viventium quam fossilum 5:665-1264〕〔G. Dal Piaz. 1916. Squalodon. Memoirie dell'Instituto geologico della R. Università di Padova 4:1-94〕 before being made the type species of a new genus, ''Microcetus''.〔R. Kellogg. 1923. Description of two squalodonts recently discovered in the Calvert Cliffs, Maryland; and notes on the shark-toothed cetaceans. Proceedings of the U. S. National Museum 62(16):1-69〕
