Primary ancient-mitogenomic study recovering partial mitochondrial genomes from one Smilodon populator and three Homotherium samples; the mitochondrial and sparse extinct sampling bound its topology.
A partial mitochondrial genome from one Smilodon populator specimen places the sampled lineage with Homotherium in a well-supported machairodont clade within Felidae, distinct from sampled living felid lineages; one Smilodon sample and mitochondrial inheritance limit broader species-level inference.
claim:taxon:smilodon:topologySmilodon is displayed at 0.012–0.01 Ma only as the dated ancient-DNA specimen window, not the full genus range. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
