VERIFY:geological_stage: stored=aptian suggested=albian confidence=medium — The current ICS chart places the Aptian at 121.4-113.2 Ma and the Albian at 113.2-100.5 Ma, so the stored 113-110 Ma window falls in the Albian, not the Aptian. Literature consistently describes Acrocanthosaurus as spanning the Aptian to early Albian, so 'albian' (or an Aptian-Albian span) matches the stored age range.
