Dinosaurs & Prehistoric Life
No one has ever seen a living dinosaur, yet we know a surprising amount about them. Ten questions on the age of reptiles, each with the story behind the answer.
About this topic
No one has ever seen a living dinosaur, yet we can describe how they moved, what they ate, and how they lived, all reconstructed from bones, footprints, and rock. This quiz covers dinosaurs and the wider prehistoric world, from the giants everyone knows to the surprising links between ancient reptiles and the birds outside your window. The explanations show how scientists actually know what they claim, which is often the most interesting part. It is a trip back through deep time, built on real evidence rather than the versions the films tend to give us.

1Roughly when did the last non-bird dinosaurs go extinct?
- A About 500 million years ago
- B About 10,000 years ago
- C About 66 million years ago Correct
- D About 2 million years ago
Answer: C. About 66 million years ago
Why: A mass extinction about 66 million years ago wiped out the non-bird dinosaurs, most likely triggered by a massive asteroid impact.
-
2What is widely believed to have caused the dinosaurs' mass extinction?
- A Human hunting
- B An ice age
- C A giant asteroid impact Correct
- D A global disease
Answer: C. A giant asteroid impact
Why: A roughly 10 km asteroid struck near today's Yucatán Peninsula, leaving the Chicxulub crater and triggering a global climate catastrophe.
-
3Modern birds are the living descendants of which dinosaur group?
- A Sauropods
- B Theropods Correct
- C Ceratopsians
- D Stegosaurs
Answer: B. Theropods
Why: Birds evolved from small feathered theropods — the same meat-eating group as Tyrannosaurus — so in a real sense dinosaurs never fully died out.
-
4During which period did dinosaurs first appear?
- A The Triassic Correct
- B The Cretaceous
- C The Cambrian
- D The Jurassic
Answer: A. The Triassic
Why: Dinosaurs first appeared in the Triassic period over 230 million years ago, then flourished through the Jurassic and Cretaceous.

- A "Three-horned face"
- B "Roof lizard"
- C "Terrible claw"
- D "Tyrant lizard king" Correct
Answer: D. "Tyrant lizard king"
Why: Tyrannosaurus rex means "tyrant lizard king", a fitting title for one of the largest land predators ever to have lived.
-
6Long-necked plant-eating giants like Brachiosaurus belong to which group?
- A Pterosaurs
- B Theropods
- C Sauropods Correct
- D Raptors
Answer: C. Sauropods
Why: Sauropods were the long-necked herbivores and include the largest animals ever to walk the Earth.
-
7Were pterosaurs, the flying reptiles of the age, actually dinosaurs?
- A No, they were flying reptiles, not dinosaurs Correct
- B Yes, they were flying dinosaurs
- C No, they were early birds
- D No, they were mammals
Answer: A. No, they were flying reptiles, not dinosaurs
Why: No — pterosaurs were close relatives that flew, but they were not dinosaurs, just as the great marine reptiles of the era were a separate group.
-
8Triceratops is best known for which feature?
- A Three horns and a bony frill Correct
- B A clubbed tail
- C Feathered wings
- D Plates along its back
Answer: A. Three horns and a bony frill

-
9What do palaeontologists mainly study to learn about dinosaurs?
- A Cave paintings
- B Tree rings
- C Living samples
- D Fossils Correct
Answer: D. Fossils
Why: Fossils — mineralised bones, teeth, footprints and even eggs — are the main evidence for what dinosaurs looked like and how they lived.
-
10Growing fossil evidence shows many dinosaurs were covered in what?
- A Bony shells
- B Scales only
- C Feathers Correct
- D Fur
Answer: C. Feathers
