Unlike other species and breeds of Velociraptor, this is the only one whose fossils have been shown across the Jurassic Universe. Named after its discovery locality, the Montana's Velociraptor is not a true Velociraptor to our Fossil understanding, but a rather dubious assumption.

The genus Velociraptor sp. has been found primarily in the continent of Asia with two known species, V. mongoliensis and V. osmolskae , this one however, is found in the USA, being considerably smaller than cloned specimens by Ingen. Two specimens have been shown across the films, one in Fort Peck Lake, and one in Badlands (both localities within Montana).

To our Fossil Record, this animal is what we call Deinonychus, but with a genus lumping, it can be misidentified with the clones of Ingen, who are not cloned out of this species. V. antirrophus is, so far, restrained to fossils only with no living specimens ever being cloned within the Jurassic Timeline.
