VERIFY:period_end_mya: stored=205 suggested=213 confidence=high — Magnetochronology of the Los Colorados Formation, the sole unit yielding Zupaysaurus, constrains it to 227–213 Ma and shows it is entirely Norian with no Rhaetian strata, ending more than 11 Myr before the Jurassic. A stored end date of 205 Ma extends the taxon roughly 8 Myr past the youngest supported age.
