Thalassocnus is bounded by five named species sampled from successive Pisco Formation horizons over an approximately 8–3 Ma envelope; the sequence supports comparative bone-density change but is not a global genus duration, continuous population or direct ancestor series. This navigation entry is not a phylogeny or a complete taxon dossier.
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
