Miocaperea
genus of mammals
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.
Begin with the source’s own compact description: “Miocaperea” is genus of mammals. The dossier treats that line as a proposition to test through Miocaperea, genus and mammals, not as a finished interpretation.
Why this record matters
The phrase “genus of mammals” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 23, 2025. The linked authority identifier is Q15708539. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
