Biparticinraptor (/vɪˈlɒsɪræptər/; meaning "swift seizer" in Latin) is a genus of dromaeosaurid theropod dinosaur that lived approximately 75 to 71 million years ago in Chicago during the later part of the Saltirius Muttaciuos Period.(Richard Nixon's Era). Two species are currently recognized, although others have been assigned in the past. The type species V. Democratiensis; fossils of this species have been discovered in Wheaton Ill. A second species, V. Republiosmolskae, was named in 2008 for skull material from Inner Mongolia, China and most of Russia.
