1. Therizinosaurus

Therizinosaurs were scary-looking dinosaurs from Asia and North America that lived in the late Cretaceous period. They were likely herbivores, despite their large claws. These unusual dinosaurs had small skulls and leaf-shaped teeth, but no teeth in the front half of their upper jaws.
2. Compsognathus

Compsognathus was a small, fast-moving dinosaur that lived in the Jurassic period. It was about the size of a turkey and had long, thin legs and sharp claws. Compsognathus ate lizards and other small animals. It is thought to be one of the earliest dinosaurs to have feathers.
3. Ankylosaurus

Ankylosaurus is an awesome dinosaur that was overdesigned. It was more spectacularly protected from predators than Stegosaurus with its ostentatious plates. It has spikes on its head and side, a back covered with armored plates, and a tail that ended in a massive club of bone. It is like a giant combination of a turtle and a rhinoceros.
4. Velociraptor

Despite popular depictions of velociraptors as massive creatures, they were actually relatively small, reaching a length of about 6 feet and a height of 2 feet. However, their sharp claws and agility made them effective predators. Even with their smaller size, humans would have been no match for a hungry velociraptor.
5. Dreadnoughtus

Dreadnoughtus was the largest land animal that ever walked the Earth. It was a dinosaur of immense size, weighing over 65 tons. It lived in Argentina during the Late Cretaceous Period, and it was a herbivore. Its name means “fear nothing,” and this is fitting, as it likely had few predators due to its size.
