Think you can tell a hadrosaur from a ceratopsian before your coffee cools? Prove it. This fast-paced dinosaur trivia quiz sprints from Triassic trailblazers to Late Cretaceous heavyweights—mixing fossil facts, name meanings, and a few curveballs about birds (yes, they’re dinosaurs). Ready when you are.
(Multiple choice; answer right after each question so you can copy/paste into a quiz app.)
Tip: For clean import into most quiz tools, keep one question per line. I’ve bundled facts that line up with museum/peer-reviewed sources cited above. The “load-bearing” claims (dates, birds-are-dinosaurs, tail-club biomechanics, T. rex bite/pressure, pterosaurs ≠ dinosaurs) are supported in the sources list; most of the rest are standard dino 101.
