 The "Deinonychus" model was used for "Saurornithoides" (rather inaccurately, as "Saurornithoides" was slenderer than "Deinonychus"), and the "Sauroposeidon" model was used for "Alamosaurus" (even though "Alamosaurus" had different proportions than "Sauroposeidon").The same "Tyrannosaurus", "Triceratops", "Ankylosaurus", and "Quetzalcoatlus" models were also used.These models were placed upon different backdrops most of the time than those used in "Clash of the Dinosaurs".
