Archaeolepidotus is an extinct, prehistoric semionotiform that lived during the Early Triassic period. Its only species is Archaeolepidotus leonardii.
It is in the order Semionotiformes. It was probably a macrosemiid or a relative of Callipurbeckia. It probably may have been a relative of the Arapaiminae.
It resembled some sort of arapaima but much shorter. It also may have resembled the African arowana.
