A 16,397-base-pair placental matrix recovers Afrotheria in its sampled topology and estimates an approximately 103 Ma split under its models; the atlas’s 100 Ma navigation ceiling is rounded model context, not a fossil occurrence, exact crown origin or African ancestor location. This navigation entry is not a phylogeny or a complete taxon dossier.

Known limits
A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
