A 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.

Phylogenomic analysis explicitly identifies the 65.35 Ma Corral Bluffs material as the oldest unequivocal legume fossil while keeping divergence estimates model-dependent.
Claim ledger
Fabaceae 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.
