Miocaperea

Miocaperea is an extinct genus of pygmy right whale from the Late Miocene Pisco Formation of Peru. Its type species is "Miocaperea pulchra".
Evolution and significance.
The discovery of "Miocaperea" is significant, because neobalaenines were previously unknown in the fossil record, except for an isolated petrosal (ear bone) from late Miocene-aged deposits in Australia. A previous study placed the divergence date of Neobalaeninae from other mysticetes at about 23 million years, and the age of "Miocaperea" lends credence to the notion of an origin for Neobalaeninae deep in the early Miocene.
