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.
