Li and colleagues illustrate sporophytes, gametophytes and stomata of Anthoceros agrestis Bonn; these named living materials provide a morphological example for hornworts, without establishing that every hornwort species has identical structures or resolving stomatal homology across land plants.

Li and colleagues illustrate sporophytes, gametophytes and stomata of Anthoceros agrestis Bonn; these named living materials provide a morphological example for hornworts, without establishing that every hornwort species has identical structures or resolving stomatal homology across land plants.
claim:taxon:anthocerotophyta:morphologytopology · medium
Two Anthoceros genome assemblies support hornwort comparative placement and reveal lineage-specific genomic features; two species cannot date Anthocerotophyta or represent every hornwort lineage.
claim:taxon:anthocerotophytafossil-range · low
Anthocerotophyta has no supported scalar temporal range in the cited evidence: two living hornwort genomes inform phylogenomics but do not establish a 470 Ma fossil or calibrated phylum boundary, so the former 470–0 Ma display is withheld.

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
