Titanosauria is represented by the Patagotitan specimen set and its sampled sauropod matrix placement; the result constrains that taxon and a body-mass analysis, not the complete clade range, origin or ancestor chain.

Claim ledger
Titanosauria is displayed at 101.8–101.4 Ma only as the directly dated Patagotitan quarry window, not the first or last appearance of Titanosauria. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.

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