Fitness and scope

topology · geochronology · range

A sampled phylogenomic and clock analysis; inferred diversification is not the fossil first appearance of Anura.

Claim ledger

divergence-time · medium

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.

claim:taxon:anura
divergence-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.
