 As no hindlimb elements are known from "Enantiornis", it might include one of the El Brete enantiornithines known only from leg bones, namely "Lectavis", "Soroavisaurus" or "Yungavolucris".However, these apparently were all smaller birds.Hindlimb material tentatively assigned to "Martinavis" and "Elbretornis" seems somewhat and a lot too small, respectively, to represent "Enantiornis".
