fossil-range · mediumCratolirion bognerianum from the approximately 115 Ma Crato Formation is anatomically preserved from roots to reproductive organs and was recovered as a crown monocot; it is a specimen-scoped occurrence, not the origin of monocots or an uncontested living-family assignment.
claim:event:crato-cratoliriontaxonomy · mediumCratolirion bognerianum was recovered as a crown monocot without an uncontested living-family assignment; it is not presented as a direct ancestor.
claim:taxon:monocotyledones:taxonomybiogeography · mediumThe 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:biogeographyecology · mediumThe fossil’s anatomy and depositional context permit a terrestrial-herb interpretation, but exact habitat and clade-wide ancestral ecology remain unresolved.
claim:taxon:monocotyledones:ecologymorphology · mediumCratolirion preserves roots, stems, leaves and reproductive organs, supplying a rare whole-plant anatomical character set.
claim:taxon:monocotyledones:morphologyfossil-range · mediumThe profile uses the approximately 115 Ma Crato occurrence as a crown-monocot fossil anchor, not the origin of monocots or a global class FAD.
