Named Haramiyavia jaws were rescored in a published morphology matrix that placed sampled Late Triassic haramiyids outside crown Mammalia; the result is matrix-bounded and not ancestry.
claim:taxon:haramiyavia:taxonomyHaramiyavia
CT scans and occlusal reconstruction of named Haramiyavia jaws document a Late Triassic haramiyidan whose placement outside crown Mammalia is specific to the cited character matrix.

Claim ledger
The profiled material comes from the Tait Bjerg Beds of East Greenland and does not establish the complete geographic distribution of Haramiyida.
claim:taxon:haramiyavia:biogeographyComplex teeth and reconstructed wear facets support plant-processing and palinal-chewing inferences, while actual diet and behaviour were not observed.
claim:taxon:haramiyavia:ecologyCT data from MCZ7/95A–B and MCZ10/G95 document the dentary condyle, postdentary trough, tooth rows and occlusal wear geometry.
claim:taxon:haramiyavia:morphologyThe 205.7–201.4 Ma envelope translates the Rhaetian formation context of the named jaws and is not a global haramiyidan FAD, LAD or crown-mammal age.
claim:taxon:haramiyavia:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
