⚠️ Disputed: the sources disagree.

What was discovered

Del Río found it in brown lead from Zimapán and called it erythronium, but retracted his claim; Sefström rediscovered it in iron from Taberg in 1830 and gave it the name vanadium.

A classic priority dispute: del Río withdrew his claim after a mistaken opinion by Collet-Descotils.
