Actually, although Velociraptor mongoliensis was about as long as a wolf,
about half that was tail. Since mass, not length, is a better descriptor
of "size" in biology, Velociraptor is a jackle-sized, not a wolf-sized,

Crichton seems to have followed Greg Paul's synonymization of Deinonychus
and Velociraptor (Velociraptor is the older name by 47 years). Very few
other paleontologists go quite so far, although most of the rest of us
agree both were closely related, members of the subfamily Velociraptorinae
in the family Dromaeosauridae.
Another (probable) sign of Paulian (Paulesque?) synonymization is in the
embryo-storage unit. Among the dinosaurs listed (including the mispelled
Stegosaurus) is Metriacanthosaurus. Although it may be that the prop-staff
intended this to be the true very-poorly known Middle Jurassic English
theropod Metriacanthosaurus, it is more likely that they meant
Yangchuanosaurus (a very well-known Late Jurassic Chinese theropod, which
Paul lumped into Metriacanthosaurus).
