An 83-plastid-gene analysis resolves several early eudicot branches in its sampled taxa; this organellar topology is not a global eudicot first appearance or a direct ancestor sequence.

Leefructus mirus is diagnosed as a basal eudicot from the Early Cretaceous Yixian Formation, while a separate 83-plastid-gene analysis resolves selected living early eudicot branches; neither result is a literal ancestor sequence. This navigation entry is not a phylogeny or a complete taxon dossier.

Claim ledger
Leefructus mirus is diagnosed as a basal eudicot from the Early Cretaceous Yixian Formation, while a separate 83-plastid-gene analysis resolves selected living early eudicot branches; neither result is a literal ancestor sequence.
claim:taxon:eudicotyledones:taxonomyThe fossil locality represented in this profile is the Daxinfangzi bed of the Yixian Formation in northeastern China; one dated locality does not establish a eudicot origin centre or global distribution.
claim:taxon:eudicotyledones:biogeographyLeefructus preserves vegetative and reproductive plant material, supporting only a bounded primary-producer context for the sampled fossil; its habitat and any class-wide eudicot ecology remain unresolved.
claim:taxon:eudicotyledones:ecologyLeefructus mirus from the Yixian Formation has deeply three-lobed leaves grouped at nodes and an axillary reproductive axis ending in five narrow, partly united carpels. These are features of the described fossil, not a universal eudicot body plan.
claim:taxon:eudicotyledones:morphologyEudicotyledones is displayed at 125.8–0 Ma only as a radiometrically bounded Leefructus-sample-to-living navigation anthology: the fossil supports basal-eudicot presence but does not establish the exact global FAD, crown divergence or continuous occupancy.
claim:taxon:eudicotyledones:range-boundary-rc50Known limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
- PBDB external identifier withheld: no-exact-name-in-snapshot.
