The Garbani Channel tarsals were attributed to Purgatorius by bounded comparative regressions and phylogenetic analyses; the isolated bones do not establish crown-Primate membership or ancestry.
claim:taxon:purgatorius:taxonomyPurgatorius
Isolated late Puercan astragali and calcanea attributed to Purgatorius preserve mobile-ankle features used to test arboreality and a primate-side placement.

Claim ledger
The profile represents the Garbani Channel fauna in Montana and does not convert that locality sample into a global Purgatorius distribution.
claim:taxon:purgatorius:biogeographyTarsal joint form supports an arboreal locomotor inference, while diet, habitual substrate use and behaviour remain unobserved.
claim:taxon:purgatorius:ecologyUCMP 197509 and UCMP 197517 preserve ankle and inverted-foot features quantified against dentally associated euarchontans.
claim:taxon:purgatorius:morphologyThe 65.2–64.4 Ma envelope is the bounded late Puercan sample context, not a genus-wide FAD, LAD, crown-Primate age or uninterrupted duration.
claim:taxon:purgatorius:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
