There were tons of dangerous dinosaurs that lived in prehistoric times. Even though we don't fully know what they looked like or how they acted, here are some of the scariest and deadliest dinosaurs we've discovered:
  • Tyrannosaurus Rex: one of the largest predators with the strongest bite force of any animal ever
  • Spinosaurus: a large semi-aquatic predator with a crocodile-like snout and a large sail on its back
  • Utahraptor: a carnivore with deadly rear claws that the raptors from Jurassic Park are actually based on
  • Quetzalcoatlus: the largest flying lizard with a wingspan of 33-36 feet (10-11 meters)
  • Velociraptor: a small predator that hunts in packs and tears apart their prey with sharp claws
  • Allosaurus: a medium-sized dino that's faster than a T-rex and has curved serrated teeth that dig into prey
  • Therizinosaurus: an herbivore that has long, blade-like front claws
  • Ankylosaurus: an armored herbivore covered in spikes that swings a club-like tail
  • Carnotaurus: a large carnivore with 2 horns above its eyes
  • Giganotosaurus: a therapod that's taller and more aggressive than the Tyrannosaurus
