Coelacanthimorpha

Genome comparisons test the placement of the living coelacanth relative to lungfishes and tetrapods while explicitly examining outgroup bias. This extant relationship test does not delimit fossil Coelacanthimorpha, its origin, or a direct tetrapod ancestor. This navigation entry is not a phylogeny or a complete taxon dossier.

divergence-time · medium

A 24-calibration relaxed-clock analysis estimated the living coelacanth split from lungfishes plus tetrapods near 409 Ma, supporting a model-to-present route rather than a fossil Coelacanthimorpha FAD.
