Catalog / order

Petromyzontida

A genomics-era synthesis documents living lamprey diversity, life-history variation and comparative genomic resources. It provides a bounded modern taxonomic context, not a fossil range, exact order origin or ancestral life cycle. This navigation entry is not a phylogeny or a complete taxon dossier.

claim:taxon:petromyzontida

fossil-range · medium

The reviewed record places undoubted fossil lampreys at about 358 Ma and living lampreys at the present, supporting a bounded 358 Ma–present evidence route but not a global order FAD.

Known limits

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
PBDB external identifier withheld: accepted-rank-mismatch.
