 Sereno suggested that it might be related to the allosauroid radiation of the Jurassic period, and this was supported in subsequent studies that recognized a clade of late-surviving, lightly built, advanced allosauroids with large hand claws similar to the spinosaurs, called the Megaraptora, within the allosaur family Neovenatoridae.A later analysis has placed Megaraptora, including "Aerosteon", within the Tyrannosauroidea.Megaraptorans have since been also considered as non-tyrannosauroid basal coelurosaurs in some analyses.
