Separately catalogued Teilhardina dental samples from three correlated PETM sections document a short Asia-to-Europe-to-North-America appearance sequence, not one tracked population or an ancestor chain.

fossil-range · medium
Separately catalogued Teilhardina dental samples in China, Belgium and Wyoming occur in correlated PETM sections within an approximately 56–55.8 Ma sequence; correlation and dental taxonomy do not make them one migrating population or a global genus origin.
claim:taxon:teilhardina:fossil-rangetaxonomy · medium
The primary study identifies separately catalogued PETM dental samples as Teilhardina in three sections, while keeping their correlated appearance sequence distinct from a single population, direct ancestry or a crown-Primate diagnosis.
claim:taxon:teilhardina:taxonomybiogeography · medium
The profiled Teilhardina samples are from the Hengyang Basin in China, Dormaal in Belgium and the Bighorn Basin in Wyoming; these three correlated localities do not establish a complete distribution or migration track.
claim:taxon:teilhardina:biogeographyecology · high
The three correlated Teilhardina samples are dental and stratigraphic evidence; they do not directly record diet, habitual habitat, locomotion, body mass or ecological guild.
claim:taxon:teilhardina:ecologymorphology · medium
Dental comparisons among separately catalogued Teilhardina samples support the reported PETM morphological sequence; no associated postcranial skeleton is documented by this comparison.

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
