Crichton wrote the novel using information from a book where the author says that Deinonychus and Velociraptor are sister species, despite them living half a world and a few tens of millions of years apart. He then combined the scientific names of the animals into one, Velociraptor antirrhopus. Now keep in mind that even back in the 80s we knew Velociraptor was a small turkey-sized animal while Deinonychus was much larger. Velociraptor also stole Deinonychus's body, what you see in the films and other media is what Deinonuchus looked like, which is why in Evolution Frontier had to go back to Deinonychus' old 1980s reconstruction by Robert Bakker.
