Juárez Valieri et al. (2004) regarded _Quilmesaurus_ as an indeterminate
carnotaurine with no valid autapomorphies. Indeed, they treated
_Quilmesaurus_ as a nomen dubium.
Translating part of the abstract, they justified the inclusion of this genus
in Abelisauridae in the basis of the marked distal expansion of the cnemial
crest and the asymmetrical distal end of the tibia. Carnotaurine characters
include distal part of cnemial crest downturned.
Incidentally, his analysis included a new theropod still undescribed:
"Ekrixinatosaurus novasi".
