Explore Dinosaurs
Dinosaurs are usually sorted by what they ate. Flying and swimming reptiles lived at the same time, but they belong to different groups — they are not dinosaurs.
Meat-eating dinosaurs
Sharp teeth, strong back legs and eyes that faced forward.
Plant-eating dinosaurs
Beaks, grinding teeth and bodies built for reaching or grazing.
Flying reptiles (not dinosaurs)
Pterosaurs such as Pteranodon flew on wings of skin. They were close relatives of dinosaurs, but a separate group.

Learn About Dinosaurs
What is a dinosaur?
Dinosaurs were land-living reptiles whose legs sat directly underneath their bodies, rather than sprawling out to the sides like a lizard’s. That one difference in the hips and legs is what separates dinosaurs from other prehistoric reptiles. Some walked on two legs, some on four, and a few could do both.
Are birds dinosaurs?
Yes. Birds descend from small feathered meat-eating dinosaurs, and scientists class them as living dinosaurs. So while the large dinosaurs died out about 66 million years ago, the dinosaur family never disappeared completely — there is one in most gardens.
Why did the dinosaurs disappear?
Around 66 million years ago a large asteroid struck what is now Mexico, at the same time as enormous volcanic eruptions in what is now India. Together these events changed the climate very quickly, and the non-bird dinosaurs did not survive. Scientists continue to study how much each event contributed.
When Did Dinosaurs Live?
Dinosaurs lived through three long stretches of time, together called the Mesozoic Era. All the dates are approximate — they come from measuring the age of rocks.
Period 1
Triassic
about 252–201 million years ago
The first dinosaurs appear. Most are small and lightly built.
Period 2
Jurassic
about 201–145 million years ago
Huge long-necked plant eaters like Brachiosaurus, and plated dinosaurs like Stegosaurus.
Period 3
Cretaceous
about 145–66 million years ago
Tyrannosaurus rex, Triceratops, Ankylosaurus and Velociraptor. It ends with the extinction.
How Big Were Dinosaurs?
These bars compare rough body lengths. Dinosaur sizes are worked out from incomplete skeletons, so different scientists give different numbers — treat these as estimates rather than exact measurements.
- Person (for comparison)about 1.7 m tall
- Velociraptorabout 2 m long
- Stegosaurusabout 9 m long
- Triceratopsabout 9 m long
- Tyrannosaurus rexabout 12 m long
- Brachiosaurusabout 18–22 m long
What Did Dinosaurs Eat?
Herbivores
Plant eaters
Most dinosaurs ate plants. Many had beaks for snipping and rows of teeth for grinding, and some swallowed leaves whole.
Triceratops · Brachiosaurus · Stegosaurus · Ankylosaurus
Carnivores
Meat eaters
Meat-eating dinosaurs walked on two legs and had curved, pointed teeth. Some hunted, and some also ate animals that were already dead.
Tyrannosaurus rex · Velociraptor · Spinosaurus
Omnivores
Both plants and animals
A few dinosaurs had teeth and claws suited to a mixed diet. Because diet has to be worked out from bones and rare fossil stomach contents, these cases are less certain than the other two groups.
Oviraptorids · Some small two-legged dinosaurs
How Do We Know About Dinosaurs?
Nobody has ever seen a living non-bird dinosaur. Everything we know comes from fossils — traces of ancient life preserved in rock.
Bones and teeth are the most common dinosaur fossils, because hard parts survive burial best. Eggs, footprints and skin impressions turn up too, and footprints are especially useful because they record how an animal was moving.
Scientists who study fossils are called palaeontologists. They search rocks of the right age, uncover fossils carefully with hand tools, record exactly where each piece was found, and then clean and study them in a laboratory.

Frequently asked questions
- When did dinosaurs live?
- Dinosaurs lived during the Mesozoic Era, from roughly 252 to 66 million years ago. That is split into the Triassic, Jurassic and Cretaceous periods.
- Why did dinosaurs become extinct?
- About 66 million years ago a large asteroid hit what is now Mexico, while huge volcanic eruptions were happening in what is now India. The climate changed very quickly and the non-bird dinosaurs did not survive.
- What was the biggest dinosaur?
- The largest known dinosaurs were long-necked titanosaurs such as Argentinosaurus and Patagotitan. Because their skeletons are incomplete, their exact size is still uncertain.
- Was T-Rex the biggest meat-eating dinosaur?
- Not the longest. Spinosaurus is the longest meat-eating dinosaur currently known, although Tyrannosaurus rex was more heavily built.
- Did dinosaurs have feathers?
- Many did. Fossils of small meat-eating dinosaurs preserve feathers, and Velociraptor arm bones carry the bumps where feathers attach. Not every dinosaur had them.
- Are birds dinosaurs?
- Yes. Birds evolved from small feathered meat-eating dinosaurs, so scientists class them as living dinosaurs.
- What do palaeontologists do?
- Palaeontologists are scientists who study fossils. They find them in rock, remove them carefully, record where they came from, and then study them to work out how ancient animals lived.
- How are dinosaur fossils found?
- Most are found where wind and rain wear rock away and expose bone at the surface. Palaeontologists search rocks of the right age, then dig carefully once they spot something.
