Miocaperea is an extinct genus of pygmy right whale from the Late Miocene Pisco Formation of Peru.^[1] Its type species is Miocaperea pulchra.^[2]

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.^[3] A previous study placed the divergence date of Neobalaeninae from other mysticetes at about 23 million years,^[4] and the age of Miocaperea lends credence to the notion of an origin for Neobalaeninae deep in the early Miocene.
