For roughly 165 million years, the dinosaurs ruled the planet. They evolved during the Triassic, dominated the Jurassic and the Cretaceous, and vanished almost overnight when a 10-km asteroid struck the Yucatán peninsula about 66 million years ago. The descendants we still see — birds — are the only branch that survived.

The 25 species in this quiz cover the giants that lived on every continent. Tyrannosaurus rex, the apex predator with a bite force of 3,500 kg. Argentinosaurus, a long-necked sauropod the length of a tennis court. The armoured tank Ankylosaurus, the spike-tailed Stegosaurus, the bone-headed Pachycephalosaurus. Plus the close relatives we love anyway — the marine Mosasaurus, the flying Quetzalcoatlus with its 10-metre wingspan.

Look at the artist's reconstruction and type the scientific name (most are identical across languages — *Velociraptor*, *Triceratops*, *Brachiosaurus*). Common nicknames work too: *T. rex*, *Brontosaurus*, *Raptor*. Three tries per dinosaur.
