The same revised cynodont matrix recovers Probainognathia as one of the two principal sampled eucynodont branches and reports low early rates relative to Cynognathia; neither result establishes a direct lineage to mammals or a clade-wide first appearance. This navigation entry is not a phylogeny or a complete taxon dossier.

Probainognathia is displayed at 237–174.7 Ma only as the sampled matrix coverage, not a clade origin, extinction or direct mammal ancestry. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
