The taxonomic position in the tree of the Aquilapoda was uncertain for a long time, at first it was presumed that the species stands at the base of the Wyvernidae (Eurovenator etc.) than some scientists suggest that it is a sister taxon of Megaceloxus and it's relatives. Today most experts accept that Brutodens is part of a own, very specialized family which secede from the rest of the Aquilapoda shortly after the first members of this suborder appeared.
