To be fair, I did catch that Alan Grant's outfits from Jurassic Park were lifted form an older dinosaur movie, Dinosaurus.

They just moved the red scarf from the first outfit to the second. (It's not how he's described in the book. There, he's a barrel-chested man with a beard, a Hawaiian shirt, and cowboy boots.)

It could be a coincidence, but the "tyrannosaurus looking into the vehicle" shot is also in both movies and Jurassic Park is peppered with references to older dinosaur films. The "When Dinosaurs Ruled the Earth" banner is a reference to a film of the same name. And they acknowledged on the Jurassic Park DVD that the scene of the gallimimus getting caught and eaten by the tyrannosaurus was a reference to an ornithomimus getting eaten by an allosaurus in The Valley of Gwangi. "What do they think they've got in there, King Kong?," etc.

Plus, the clothing department already had fun with Dennis Nedry wearing the various outfits that Chunk wore in The Goonies. I don't know. The more I try and justify it, the more I feel it might just be a coincidence. I'd like to feel that I'm onto something though.
