Dinosaurs and Prehistoric Life

About Dinosaurs and Prehistoric Life

Travel back hundreds of millions of years to meet the giants, hunters, and strange creatures that ruled the Earth long before us. Dinosaurs and Prehistoric Life packs 15 multiple-choice questions aimed at mixed difficulty into a relaxed session of roughly 7 minutes — no sign-up, no timer pressure. An explanation appears after every answer, and finishing once a day keeps your streak alive.

A few sample questions

1. 1. Velociraptor is a member of which major dinosaur group?

   Answer: Theropods

   Velociraptor was a theropod — the group of mostly two-legged, often meat-eating dinosaurs that also includes T. rex, and from which modern birds are descended.

2. 2. The Mesozoic Era is divided into three periods. Which came FIRST?

   Answer: Triassic

   The Mesozoic Era began with the Triassic period about 252 million years ago, followed by the Jurassic and finally the Cretaceous, which ended about 66 million years ago.

3. 3. What is the name of the massive impact crater left by the asteroid that ended the age of non-bird dinosaurs?

   Answer: Chicxulub Crater

   The Chicxulub impactor struck what is now Mexico's Yucatan Peninsula roughly 66 million years ago, creating a crater about 110 miles wide and triggering the mass extinction that wiped out most of the world's species.

4. 4. In what year did Megalosaurus become the first dinosaur to receive an official scientific name?

   Answer: 1824

   Geologist William Buckland formally described and named Megalosaurus bucklandii in 1824, making it the first dinosaur ever given a scientific name — 18 years before the word 'dinosaur' was even coined.

5. 5. Which pioneering fossil hunter discovered the first ichthyosaur and plesiosaur skeletons along the cliffs of Lyme Regis, England?

   Answer: Mary Anning

   Mary Anning, a self-taught fossil hunter who began collecting fossils as a child in the early 1800s, made some of the 19th century's greatest paleontological discoveries — though as a woman of her era she rarely received formal credit.

Things you'll learn along the way

• ✓Triceratops was a ceratopsian, or 'horned-face' dinosaur — a group of plant-eaters distinguished by bony neck frills and horns that lived primarily during the Cretaceous period.
• ✓The Bone Wars was a decades-long feud between Edward Drinker Cope and Othniel Charles Marsh, who raced to discover and name new dinosaur species — together naming more than 130 new species, though their rivalry often led to sloppy science and sabotage.
• ✓Unlike most sauropods where the hind legs are the longest, Brachiosaurus had notably longer front limbs — the name itself means 'arm lizard' — so its back sloped downward from shoulders to hips, much like a modern giraffe.
