Placentalia

The 100–0 Ma Placentalia route is a model envelope: a molecular analysis estimated a roughly 103 Ma deep placental split, whereas the phenomic combined analysis placed sampled crown diversification after K–Pg; neither model is a fossil FAD or ancestor observation. This navigation entry is not a phylogeny or a complete taxon dossier.
