 A very close relative of "Aerosteon", "Murusraptor", was described in 2016 which preserved some bones with a lesser level of pneumaticity.However, the "Murusraptor" holotype also preserved several teeth which were very dissimilar to the one tooth observed in "Aerosteon's" holotype.The authors of the description noted that this tooth closely resembled that of abelisaurids and was probably incorrectly referred to "Aerosteon".
