Cratolirion bognerianum was recovered as a crown monocot without an uncontested living-family assignment; it is not presented as a direct ancestor.
claim:taxon:monocotyledones:taxonomyMonocotyledones
Cratolirion bognerianum provides an approximately 115 Ma, root-to-flower anatomical sample recovered as a crown monocot without fixing a living-family assignment.

Claim ledger
The highlighted fossil comes from the Crato Formation of Brazil and does not establish a monocot origin centre or complete Early Cretaceous range.
claim:taxon:monocotyledones:biogeographyThe fossil’s anatomy and depositional context permit a terrestrial-herb interpretation, but exact habitat and clade-wide ancestral ecology remain unresolved.
claim:taxon:monocotyledones:ecologyCratolirion preserves roots, stems, leaves and reproductive organs, supplying a rare whole-plant anatomical character set.
claim:taxon:monocotyledones:morphologyThe profile uses the approximately 115 Ma Crato occurrence as a crown-monocot fossil anchor, not the origin of monocots or a global class FAD.
claim:taxon:monocotyledones:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
