Phylogenomic sampling and fossil-calibrated clocks infer rapid diversification among three sampled Gondwanan frog clades near the K–Pg boundary. The modeled diversification interval is not the fossil first appearance or exact origin of Anura as a whole. This navigation entry is not a phylogeny or a complete taxon dossier.

claim:taxon:anuradivergence-time · medium
The fossil-calibrated phylogeny inferred rapid diversification of three sampled Gondwanan frog clades near 66 Ma, supporting a 66 Ma–present model window for those lineages, not an Anura fossil FAD.

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