Found these Jurassic Park/JP The Lost World toys online, and had to share. Either these were only in the novels, or they were originally intended for the films, but never made it in. A couple of them were just really hard to find in stores when they were released.
Baryonyx (electronic sounds)
Carnotaurus “Demon” with longer than real-life ACTION LIMBS!! I could never find this one in stores.
Dimetrodon, which I can’t remember from the book, it might have been a species intended for the movie, but ended up getting cut.
Lycaenops - an early Triassic therapsid.
Parasaurolophus. I could never find this one in stores, even though it was on the packaging of other JP dinos.
Pteranodon, with articulated flap-flaps!
Quetzalcoatlus, with action muzzle and blinders!
Tanystropheus, the long-necked fishing reptile
Young T-Rex, with Battle Damage
So these are the rarest of JP toys. Some, like the Coelophysis, were basically latex molded over a wire frame, so they could be bent into poses. Others like the Big Rex and the Young rex were a plastic armature with a latex rubber or silicone “skin”. But they did represent the most realistic depictions of dinos from 1993-1997.
