Many children find dinosaurs utterly captivating. Perhaps it’s because these ancient creatures resembled monsters, yet they actually roamed the same landscapes we know today. While the thought of such massive beings may seem daunting, the comforting fact is that dinosaurs are long gone, allowing kids to explore their remains in museums or dream of discovering fossils while digging in the backyard. If your little paleontologist is eager to learn about the diverse groups of dinosaurs that existed, here’s a guide to some of the most notable types.
Types of Dinosaurs
Theropods
Theropods were meat-eating dinosaurs, characterized by their strong legs and three-toed, bird-like feet with sharp claws. They also had relatively short arms, exemplified by the famous T. Rex.
Other theropods include:
- Albertosaurus
- Allosaurus
- Baryonyx
- Carnotaurus
- Coelophysis
- Compsognathus
- Deinonychus
- Giganotosaurus
- Megalosaurus
- Ornithomimus
- Oviraptor
- Saurophaganax
- Spinosaurus
- Tyrannosaurus
- Tyrannotitan
- Velociraptor
- Yangchuanosaurus
Sauropods
Sauropods had small heads, long necks, and long tails, moving on all four legs. Unlike theropods, they were herbivores, feasting on plants.
Examples include:
- Apatosaurus
- Brachiosaurus
- Diplodocus
- Giraffatitan
- Jobaria
- Macrurosaurus
- Mamenchisaurus
- Seismosaurus
- Zigongosaurus
Stegosaurs
Known for their bony plates and spikes, stegosaurs, like the Stegosaurus, were generally slow movers.
Examples include:
- Kentrosaurus
- Stegosaurus
- Chialingosaurus
- Wuerhosaurus
- Tuojiangosaurus
- Chungkingosaurus
- Huayangosaurus
- Yingshanosaurus
- Gigantspinosaurus
- Jiangjunosaurus
Ankylosaurs
These small to medium-sized dinosaurs were covered in flexible bony slabs or plates.
Examples include:
- Ankylosaurus
- Minmi
- Euoplocephalus
- Nodosaurus
- Edmontonia
- Sauropelta
- Pinacosaurus
- Polacanthus
- Gastonia
- Mymoorapelta
Cerapods
Cerapod dinosaurs typically had four legs and three horns, often living in large herds. Some had bony frills around their faces, while others boasted parrot-like beaks.
Examples include:
- Psittacosaurus
- Styracosaurus
- Triceratops
Ornithopods
These dinosaurs ran on two hind legs and were known for their bird-like feet. They varied greatly in size.
Examples include:
- Corythosaurus
- Lesothosaurus
- Iguanodon
- Parasaurolophus
Pachycephalosaurs
With their thick skulls, these dinosaurs walked on their hind legs and lived in herds.
Examples include:
- Stegoceras
- Pachycephalosaurus
- Prenocephale
