T. rex couldn't actually roar, raptors had feathers, and birds are literally dinosaurs.
Here's a fact that rewires how you think about deep time: T. rex is closer in time to you than it is to Stegosaurus. The two iconic dinosaurs were separated by roughly 84 million years — longer than the gap between T. rex and today. Dinosaurs ruled Earth for about 165 million years across three distinct periods of the Mesozoic Era, before an asteroid roughly 10–15 km wide ended the Cretaceous period 66 million years ago. Their legacy lives on — literally — in every bird you've ever seen.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
You'll explore the truth behind Jurassic Park myths (Velociraptors were turkey-sized, T. rex probably boomed rather than roared, Dilophosaurus had no frill and no venom), the staggering physics of T. rex (8,000 kg body, 12,800 lb bite force, arms that could still curl 430 lbs), the feathered dinosaur revolution from Archaeopteryx to Microraptor's four wings, how the Chicxulub impactor ended 75% of all species in the most violent event in recorded Earth history, and why the word "dinosaur" wasn't even coined until 1842.
Possibly, at least partially. We know that Yutyrannus huali — a 9-metre tyrannosaur closely related to T. rex — was covered in filamentous feathers. Fossilised T. rex skin patches suggest some areas had scaly skin, but many palaeontologists believe juveniles or at least portions of the body may have had feather-like covering. The broader takeaway is clear: feathers evolved much earlier in theropod dinosaurs than previously thought, and birds inherited them directly.
An asteroid roughly 10–15 km wide struck what is now the Yucatán Peninsula of Mexico 66 million years ago, creating the Chicxulub crater (about 180 km wide). The impact released energy equivalent to roughly 10 billion Hiroshima-scale nuclear bombs, triggering global firestorms, a "nuclear winter" from dust and soot blocking the sun, and rapid acidification of the oceans. About 75% of all species on Earth went extinct. Small, burrowing mammals — our ancestors — survived by sheltering underground and eating seeds and insects.
Yes — birds are not descended from dinosaurs in the colloquial sense; they ARE dinosaurs. Specifically, birds are avian theropod dinosaurs that evolved from within the maniraptoran clade. The earliest well-known bird, Archaeopteryx, dates to about 150 million years ago and shows a clear mosaic of dinosaur features (teeth, clawed wings, bony tail) alongside bird-like ones (feathers, wishbone). Every living bird is a dinosaur that survived the mass extinction — making the dinosaurs far from extinct.
