Tetrapodomorpha

A systematic synthesis integrates sampled Devonian tetrapodomorph fishes and early digit-bearing tetrapods into an explicit transition framework. The framework does not identify one direct ancestor, an exact Tetrapodomorpha origin, or a complete global fossil range. This navigation entry is not a phylogeny or a complete taxon dossier.

Clack’s synthesis documents tetrapodomorph and early tetrapod samples across the Late Devonian, supporting a 385.3–358.86 Ma transition-study window rather than a global clade origin or duration.

Known limits

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