The primate-origins synthesis treats Plesiadapiformes as a diverse Paleogene assemblage whose relationship to crown Primates remains central and contested; the atlas label is not a claim that all included families form one crown-primate ancestor group.

plesiadapiformes is displayed at 66–34 Ma only as the review's heterogeneous sampled assemblage, not a monophyletic crown-primate range. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
