The genus _Therosaurus_ was erected (Fitzinger, 1840) before _I.
bernissartensis_ was named (Boulenger in Beneden, 1881). _I.
bernissartensis_ was made the type species of _Iguanodon_ in 2000.
_Therosaurus_ was put forward by Fitzinger as an arbitrary replacement
name for _Iguanodon_, for no good reason (at least, none apparent to
me).
But the literature seems to use trossingensis for material once
assigned to engelhardti, which is concerning.
