Though a fourth installment of the Jurassic Park franchise is supposed to be in the works, one script has already been trashed and it featured some bizarre creatures. The John Sayles version included genetically engineered di-hu-dogs that were intelligent and wielded weapons (Di-hu-dogs stands for dinosaur human dog hybrids).
Carlos Huante worked up some concepts for that monstrosity, and they are uh, interesting. I’m just going to hypothesize that maybe these were part of the reason that execs didn’t like the script.
See more illustrations of the dog-human-osaurs after the break.
