Mammaliamorpha

A broad Mesozoic-mammal character analysis uses Mammaliamorpha for the sampled branch that includes tritylodontids and mammaliaforms, while alternative definitions and matrices alter several basal placements; the label is not a dated crown or direct-ancestor category. This navigation entry is not a phylogeny or a complete taxon dossier.

Mammaliamorpha is displayed at 225–0 Ma only as the review's definition-dependent sample envelope, not an exact clade origin or direct ancestor sequence. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.

Known limits

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
PBDB external identifier withheld: lineage-incompatible.
PBDB mapping requires concept review because the pinned lineage is incompatible with the local expected parent Probainognathia.
