Every single answer here is either wrong or could have multiple answers. For terrible lizard, assume you mean the latin translation of tyrannosaurus which is tyrant lizard, not terrible. Pterodactylus (pterodactyl) or any other pterosaur, was not a dinosaur despite them being closely related. Many dinosaurs have long, sharp claws on their back legs, many are longer than velociraptor. Triceratops is not the only dinosaur with three horns. Stegosaurus is not the only dinosaur with bony plates and a spiked tail. Giganotosaurus (not Gigantosaurus which was a genus of sauropod) is not the largest meat-eating dinosaur ever discovered, it is either spinosaurus, tyrannosaurus, or carcharodontosaurus, it is not known which, it is a myth that giganotosaurus is larger than tyrannosaurus. Brachiosaurus is not the largest herbivore ever discovered, there are a few possible largest herbivores, some of them being argentinosaurus and patagoniasauraus. (continues in
