NUFV 405 was placed within Pinnipedimorpha by the source matrix; the result does not make Puijila a direct ancestor of seals.
claim:taxon:puijila:taxonomyPuijila
Holotype NUFV 405 preserves about 65% of one skeleton, combining terrestrial limb proportions with traits used to infer freshwater swimming.
Represented range24–20 Ma
Content packagecarnivora
PBDBtxn:146163
Evidence boundary
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
Claim ledger
The profile represents one Haughton Formation lake occurrence on Devon Island and does not establish a complete Arctic dispersal route.
claim:taxon:puijila:biogeographyDentition and limb proportions support predatory and semiaquatic interpretations, but freshwater use and swimming behaviour were not directly observed.
claim:taxon:puijila:ecologyNUFV 405 preserves roughly 65% of an associated skeleton, including skull, vertebrae and substantial fore- and hind limbs.
claim:taxon:puijila:morphologyThe 24–20 Ma envelope is a broad early Miocene formation translation for NUFV 405, not a pinnipedimorph FAD, genus LAD or transition duration.
claim:taxon:puijila:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
