IVPP V16051 is the holotype of Liaoconodon hui and is treated as a eutriconodont in the source; this navigation placement does not assert direct ancestry.
claim:taxon:liaoconodon:taxonomyLiaoconodon
Near-complete holotype IVPP V16051 preserves a detached ectotympanic and malleus linked to the dentary by ossified Meckel’s cartilage, documenting one anatomical mosaic rather than a universal transition stage.
Represented range121.4–113.2 Ma

Evidence boundary
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
Claim ledger
The profiled occurrence is limited to the Jiufotang Formation near Jianchang in Liaoning and is not a complete geographic range for Eutriconodonta.
claim:taxon:liaoconodon:biogeographyDentition supports a small faunivorous interpretation and the skeleton supports terrestrial locomotion, but diet, habitat use and performance were not observed.
claim:taxon:liaoconodon:ecologyThe near-complete holotype preserves ectotympanic and malleus elements detached from the dentary yet linked by ossified Meckel’s cartilage.
claim:taxon:liaoconodon:morphologyThe 121.4–113.2 Ma display envelope translates the Aptian formation context and is not a specimen date, global FAD, LAD or universal jaw–ear transition interval.
claim:taxon:liaoconodon:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
