In January 1996 the remains of Neuquenraptor were found near Plaza Huincul in the Sierra del Portezuelo and reported that very year. In 1997 it was revealed the intended name was "Araucanoraptor argentinus". In 1999 it was provisionally described as a member of the Troodontidae. Neuquenraptor is estimated to have measured 1.8 metres (5.9 ft) long.
