The fossil legume record represented here is the 65.35 Ma Corral Bluffs fruit and leaflets in Colorado, United States; it does not establish a geographic origin or continuous global distribution of Fabaceae.

Corral Bluffs stratigraphic synthesis includes a 65.35 Ma fossil fruit and leaflets assigned to Leguminosae in Figure 3J–K.
Claim ledger
The Corral Bluffs fruit and leaflets support a bounded plant fossil record, but they do not directly establish habitat, diet, physiology or one ecological guild for Fabaceae.
claim:taxon:fabaceae:ecologyA 65.35 Ma Corral Bluffs fruit and leaflets are assigned to Fabaceae; these structures demonstrate a bounded family-level fossil record rather than a subfamily assignment or universal legume morphology.
claim:taxon:fabaceae:morphologyFabaceae is displayed at 65.35–0 Ma only as a Corral-Bluffs-fossil-to-living navigation anthology: the dated fruit and leaflets support family presence but not an exact crown origin, subfamily assignment, direct ancestry or continuous global occupancy.
