T-Rex, Triceratops, and 160 million years of prehistoric life. How much do you know?
Dinosaurs ruled Earth for over 160 million years — roughly 800 times longer than modern humans have existed. Scientists have identified over 1,000 distinct dinosaur species, and new species are discovered at a rate of about one every two weeks. This quiz covers everything from T-Rex to the asteroid that ended it all.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore the Triassic, Jurassic, and Cretaceous periods, learn about famous species from Velociraptors to Brachiosaurus, and discover how modern birds are literally living dinosaurs. Whether it's the asteroid impact or the discovery of feathered dinosaurs, every question teaches something fascinating.
An asteroid approximately 7.5 miles (12 km) wide struck what is now the Yucatán Peninsula in Mexico about 66 million years ago, creating the Chicxulub crater. The impact triggered massive tsunamis, wildfires, and a "nuclear winter" effect that blocked sunlight, killing about 75% of all species on Earth.
The largest dinosaur known is Argentinosaurus, a titanosaur that may have weighed up to 100 tons and measured 115 feet long. Patagotitan, another titanosaur discovered in Argentina, is a close contender at roughly 70 tons. New discoveries continue to challenge size records.
Yes, modern birds are technically living dinosaurs. They evolved from small theropod dinosaurs during the Jurassic period, about 150 million years ago. Fossil evidence, including feathered dinosaurs like Archaeopteryx, clearly shows the evolutionary link between theropod dinosaurs and modern birds.
