Under the cited autocorrelated-clock analysis and calibration strategy A, the posterior interval for crown Primates is 79.2–70.0 Ma; this model interval is not a fossil first appearance.

Open manuscript is available through PMC6005039. Node ages are Bayesian model outputs and vary with fossil-calibration strategy and relaxed-clock model.
Claim ledger
The 79.2–0 Ma Primatomorpha route is a navigation-model envelope borrowed from the cited crown-Primates relaxed-clock interval and living continuation; it does not date the Primatomorpha node or provide a fossil FAD.
claim:taxon:primatomorpha:root-rangeA 372-species relaxed-clock analysis estimates crown Primates at 79.2–70.0 Ma under its selected autocorrelated model and calibration strategy A, whereas another calibration strategy is younger; neither posterior interval is a fossil occurrence or exact crown-origin observation.
