Velociraptor FYI

What species are the Raptors in Jurassic Park?

In canon, nobody in Jurassic Park actually knows what kind of Raptor the "Velociraptors" in the park are. They just assumed them to be Velociraptor mongoliensis from where the amber was found (namely China).

There haven't been attempts (in universe) to reconcile the size of the animals with their presumed prehistoric original – because they just planned to defer these checks to the experts "later on" when the park would have been revealed to the world…

Here is an excerpt from the Book:

Grant said, “How do you know if it’s developing correctly? No one has ever seen these animals before.”

Wu smiled. “I have often thought about that. I suppose it is a bit of a paradox. Eventually, I hope, paleontologists such as yourself will compare our animals with the fossil record to verify the developmental sequence.”

Ellie said, “But the animal we just saw, the velociraptor—you said it was a mongoliensis?”

“From the location of the amber,” Wu said. “It is from China.”

“Interesting,” Grant said. “I was just digging up an infant antirrhopus. Are there any full-grown raptors here?”

Therefor the answer is NOT Velociraptor antirrhopus, Velociraptor mongoliensis, Deinonychus spec., Utahraptor spec., … while Michael Crichton surely had Deinonychus antirrhopus (Ostrom, 1969) in mind when writing Jurassic Park, the in-universe-answer is "nobody actually knows".
