Velociraptor vs. Utahraptor

PaleoWorld

So I'm sure that this has been asked and discussed plenty of times before but I wanted to find out from everyone. In all the Jurassic park movies we see velociraptor as an antagonist. My question to everyone is how come they used velociraptor instead of other dromeosaurs? Like Deinonycus or Utahraptor? After watching the films so many times and studying paleontology for years I am intrigued in why they chose this. Velociraptor was a very interesting dinosaur, no doubt about that, yet it is not portrayed right in the movies. It is far larher and not to scale. I have always wondered why they did not choose to use utahraptor as the better animal. It is actually the right size and was also from research possibly a more lethal predator. Anyone have thoughts?

Common misconception: The JP raptors aren't Velociraptors. They're most likely Dienonychus.

the director knew of deinonycus but wanted velociraptor cause it sounded cooler.

possible because most viewrs know more of about velceraptors

Velociraptors were actually alot smaller in real life.

They're Velociraptor. They're super inaccurate, all the dinosaurs are inaccurate on JP films, so...

technically the Velociraptors in Jurassic Park are Dienonychus and not Velociraptors. The Dr. Grant was digging up its skeleton in Montana where Dienonychus fossils are found rather than Mongolia/China were velociraptor fossils are found.

Utahraptors were discovered later during filming yes but had the opposite problem of the velociraptor, they were too big. The dakotaraptor is more portionalized to the movie raptors than either Dienonychus and Utahraptor
