The CT, dental-wear and phylogenetic study uses MCZ7/95A–B and MCZ10/G95; its character data are archived as MorphoBank Project 2292.

topology · mediumCT anatomy and dental wear from MCZ7/95A–B and MCZ10/G95 informed a rescored matrix that placed Late Triassic haramiyids outside crown Mammalia, while the postdentary trough supports rather than directly preserves a mandibular middle ear.
claim:event:haramiyavia-ct-crown-boundarytaxonomy · mediumNamed 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:taxonomybiogeography · mediumThe profiled material comes from the Tait Bjerg Beds of East Greenland and does not establish the complete geographic distribution of Haramiyida.
claim:taxon:haramiyavia:biogeographyecology · mediumComplex teeth and reconstructed wear facets support plant-processing and palinal-chewing inferences, while actual diet and behaviour were not observed.
claim:taxon:haramiyavia:ecologymorphology · mediumCT data from MCZ7/95A–B and MCZ10/G95 document the dentary condyle, postdentary trough, tooth rows and occlusal wear geometry.
claim:taxon:haramiyavia:morphologyfossil-range · mediumThe 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.
