Jurassic Park (film)
Camarasaurus didn't appear to be one of the species cloned by InGen in the original film. However, the skeleton of an unidentified sauropod is seen in the rotunda of the Visitor's Center, along with a Tyrannosaurus rex skeleton. The skeletons were posed as if the tyrannosaur was attacking the sauropod. It may have been a Camarasaurus, since the size and general body shape match the genus.

Comics
Camarasaurus is featured in the comic The Lost World. But it is unknown if the animal really was a Camarasaurus.
