Lepidodendrales

A morphology matrix of anatomically preserved Carboniferous Euramerican arborescent lycopsids tests relationships among Lepidodendrales; it neither identifies a direct ancestor nor establishes the order's global first or last appearance. This navigation entry is not a phylogeny or a complete taxon dossier.

Lepidodendron has no supported scalar temporal range here because the navigation record mixes a genus-level ID with a broader Lepidodendrales/arborescent-lycopsid concept, and the cited Carboniferous matrix does not define global endpoints; the former 359–299 Ma display is withheld.

Known limits

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
PBDB mapping requires concept review because the pinned lineage is incompatible with the local expected parent Lycopodiophyta.
