Claim ledger
The six represented Beiyanerpeton specimens come from the Tiaojishan Formation at Hengdaozi in western Liaoning, China; no global range is inferred.
claim:taxon:beiyanerpeton:biogeographyLarval structures inform developmental interpretation, but diet, precise habitat preference, locomotor performance and trophic guild remain unavailable.
claim:taxon:beiyanerpeton:ecologyThe articulated Beiyanerpeton series preserves salamandroid anatomy and larval structures interpreted as evidence of neoteny.
claim:taxon:beiyanerpeton:morphologyThe displayed 160–154 Ma interval bounds the Oxfordian sample; the 157 ± 3 Ma zircon date comes from overlying rock rather than directly from a skeleton.
claim:taxon:beiyanerpeton:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
