Easy questions

What is the largest group of long-necked herbivorous dinosaurs, such as Diplodocus or Brachiosaurus?

Answer: Sauropods. Sauropods are quadrupedal herbivorous dinosaurs characterized by a long neck, a long tail, and often gigantic size. Diplodocus and Brachiosaurus are famous examples.

Which dinosaur has triangular bony plates running along its back and spikes on its tail?

Answer: Stegosaurus. Stegosaurus is recognizable by its large bony back plates, whose exact purpose (defense, thermoregulation, display) is still debated, and its tail tipped with spikes known as a "thagomizer".

What do we call scientists who study dinosaurs and other fossils?

Answer: Paleontologists. Paleontology is the science that studies fossils and extinct organisms, including dinosaurs. It is distinct from archaeology, which studies the remains of human societies.

Which armored dinosaur has a large bony club at the end of its tail?

Answer: Ankylosaurus. Ankylosaurus was covered in bony plates (osteoderms) and had a rigid tail club it likely used as a defensive weapon against predators.

On which continent did Tyrannosaurus rex live?

Answer: North America. Tyrannosaurus rex fossils have mainly been discovered in western North America, notably in the present-day states of Montana, Wyoming, and South Dakota, as well as in Canada.

Which quadrupedal herbivorous dinosaur has a club-shaped tail and a very wide, low-slung body?

Answer: Euoplocephalus. Euoplocephalus, like other ankylosaurs, had a stocky body armored with bony plates, as well as a tail ending in a heavy club likely used for defense against predators.

Dimetrodon, with its large sail on its back, often turns up among dinosaur toys. Why isn't it a dinosaur?

Answer: It lived before the dinosaurs and was closer to mammals. Dimetrodon lived in the Permian, about 295 to 272 million years ago, more than 40 million years before the first dinosaurs appeared. It is a synapsid, a group that much later gave rise to mammals.

What is the size of the brain of Stegosaurus, a 9-metre animal, often compared to?

Answer: A walnut. It was long believed to have a 'second brain' in its hips: it was actually a nerve cavity. That did not stop it surviving for millions of years.

In which geological period did the first dinosaurs appear, about 230 million years ago?

Answer: Triassic. The Mesozoic is divided into the Triassic, Jurassic and Cretaceous. The first dinosaurs were small and walked on two legs.

Hard questions

What does the word "dinosaur", coined by paleontologist Richard Owen in 1842, literally mean?

Answer: Terrible lizard. The word "dinosaur" comes from the Greek "deinos" (terrible, fearsome) and "sauros" (lizard). It was coined by British paleontologist Richard Owen to describe this new group of fossil reptiles.

What is the name of the first dinosaur to be officially named and scientifically described, in 1824?

Answer: Megalosaurus. Megalosaurus, described by William Buckland in 1824, is the first dinosaur genus to be formally named and published in scientific literature, even before the word "dinosaur" was coined.

Based on fossilized nests found so far, how many eggs could a female dinosaur lay in a single clutch?

Answer: About a dozen to several dozen eggs. Fossilized nests found so far, notably from dinosaurs like Maiasaura, show clutches ranging from around a dozen to thirty eggs, arranged in a circle or spiral pattern.

Which dinosaur's name means "spiked dragon head", referring to its frill lined with spikes?

Answer: Styracosaurus. Styracosaurus was a ceratopsian with a frill bristling with long bony spikes, along with a prominent nasal horn, making it one of the most striking frilled dinosaurs.

Which 19th-century English palaeontologist, a pioneer of the field, discovered fossil marine reptiles on the coast at Lyme Regis?

Answer: Mary Anning. Although best known for her discoveries of fossil marine reptiles in 19th-century England (such as the ichthyosaur), Mary Anning is considered one of the pioneers of modern paleontology, paving the way for the scientific study of dinosaurs.

Which American industrialist gave casts of the skeleton of 'Dippy', a Diplodocus, to museums around the world, including Paris, in the early 20th century?

Answer: Andrew Carnegie. The steel magnate wanted to spread science… and his name. The replica given to the Paris Natural History Museum in 1908 is still on display.

On which continent was Cryolophosaurus, a crested carnivorous dinosaur, found, proving that dinosaurs lived there too?

Answer: Antarctica. At the time the continent was not covered in ice and lay further north. Its strange crest earned it the nickname 'Elvisaurus', after Elvis Presley's hairstyle.

What are the "gastroliths" found with some herbivorous dinosaur skeletons?

Answer: Stones swallowed to help grind plants in the stomach. Like today's birds that swallow grit, these polished stones crushed food, since the animals lacked teeth able to chew.
