Bonaparte & Powell, 1980
Cretaceous Late ?Campanian Maastrichtian
Saurischia Theropoda Abelisauridae
Lecho Formation, El Brete, Salta Argentina
Genus - Typespecies - Skull
A partial left maxilla, right quadrate, right squamosal, cervical neural arch, dorsal centrum, cervical rib, right metatarsal II, phlalanx of pes, ungual phalanx. Large antorbital fenestra, cervical neural arches with prominent cranially and caudally directed spines, and unguals with flexor pits rather than tubercles.
Fragmentary remains including parts of the skull, some vertebrae and two foor bones- including a large claw. The foot claw seems to be of the large slashing type seen on the foot of dromaeosaurids. However, the form of the claw is such that it could not have evolved from the type of claw seen in dromaeosaurids, but must have evolved quitte indepen dently. Bonaparte & Powell, 1980 classified in its own family, Noasauridae, since 1991 its placed in the Abelisauridae. Its lightly built jaws resemble Abelisaurus\\\\\\\'s robust jaws.
