And don't forget Phil Tippett who was going to make stop motion (Go-Motion actually) dinosaurs untill ILM showed what they could do with CGI
Indeed, what ILM did with Jurassic Park is what started Lucas onto the possibility of doing the SW prequels.
Jurassic Park, to this day, has one of my favourite CGI effects; where the dinosaurs are feeding around the water hole when Hammond is showing the island off to Alan and Ellie. I look at it and can believe that the dinosaurs where there.
