The reviewed stegosaur body-fossil record runs from the Middle Jurassic into the Early Cretaceous, with no definitive younger record in that synthesis; these literature bounds are not exact global origination or extinction instants.

Stegosauria is displayed at 174.7–100.5 Ma only as the review's stage-level body-fossil coverage, not exact origination or extinction instants. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.

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