I have published (in Dinosauria II) my speculation that Rapator is a giant
early alvarezsaurid. However, now that I have a cast of the specimen, and
with the information of megaraptorans in hand (as it were), I reject my
earlier speculation and much more strongly support Rapator as a basal
tetanurine, possibly a megaraptoran.
