- Accidentally Correct Writing: Almost exclusively the novel, but Brosnan turned out to be on the ball several times.
- Sometime after the novel was written, Scolosaurus became synonymous with Euoplocephalus. But then in 2013, Scolosaurus turned out to be its own valid genus after all.
- The novel describing the Tarbosaurus feed in a method very similar to a bird, by pinning the food down with its foot and pulling strips of meat off with its front teeth in place of a beak actually lines up very nicely with 2010s hypotheses about how large theropods ate.
- Depicting the Deinonychus as able to climb effectively was widely considered inaccurate in the 1980s by all but a few researchers. More recent evidence in the 2000s onwards indicate all but the absolute heaviest dromaeosaurids were actually very good climbers and juvenile Deinonychus might have been heavily arboreal to avoid predators with even the adults still able to climb effectively.
- There is one case of this in the film. A brief shot of the Deinonychus as a hatchling shows it with feathers, although when it becomes an adult it is scaly. This was presumably done to show that the dinosaurs were spliced with chicken DNA. Nowadays, of course, it's generally agreed that Deinonychus and other small predatory dinosaurs had feathers naturally.
- Fan Nickname: "Carnosaurs" for the second movie, due to its plot being extremely similar to another sequel with a plural title.
- Prop Recycling: The Marines' uniforms in Carnosaur 3 are the same urban camouflage BDUs from The Rock. An in-series example is the Tyrannosaurus rex prop, that was reused movie to movie. By the time it was used for "Eden Formula", you can tell the prop has degraded.
- Science Marches On: While reasonably accurate for its day (The book, not the movie, there is nothing remotely accurate about the movie), Carnosaur is still over 30 years old, so....
- Deinonychus is portrayed as scaly and using its claws like scythes. We now know that deinonychosaurs had feathers and used their toe claws as hooks.
- It is now known that plesiosaurs cannot lift their necks above water or move on land, and they do not reproduce by laying eggs.
- Scolosaurus is now known to be almost identical to Euoplocephalus; the two spikes once thought to have been protruding from the tail club were actually located halfway down the tail.
- It used to be thought that some theropods could be at least partially quadrupedal, and the Atispinax is portrayed as such in the novel. This is now seen as anatomically impossible. Although Spinosaurus (which, despite also having the word spine in its name, is of no relation to Altispinax) was once considered to have been quadrupedal due to having short hind legs, but even that was disputed and it has been reestablished as a short-legged biped.
- During much of the 20th Century, it was believed Megalosaurus lived during the Cretaceous as well as the Jurassic, as it was described in the novel. This was because remains of Early Cretaceous theropods discovered in England had been originally assigned to Megalosaurus, but have since turned out to be from different genera.
- Back when the novel was written, several of the featured dinosaurs (namely Tyrannosaurus, Tarbosaurus, Megalosaurus, and Altispinax) would have been considered carnosaurs, as it was thought at the time that all large theropods were fairly closely related. Carnosauria has recently been redefined as Allosaurus and its close relatives, leaving Altispinax as the only actual carnosaur in the book. Incidentally, this means none of the dinosaurs in any of the movies are actually carnosaurs.
- What Could Have Been: Originally the third film was not supposed to be a Carnosaur film and was instead going to be a stand-alone film that just recycled the props. In some territories such as Japan, it was still released as such under the title "Dinosaur Crisis".
