DinosaursTrivia Questions & Answers
Picture a world ruled for over 160 million years by creatures unlike anything alive today, where some giants stretched longer than a tennis court and others were no bigger than a chicken. Dinosaurs first appeared roughly 230 million years ago during the Triassic Period, then dominated land ecosystems across the Jurassic and Cretaceous. They came in staggering variety, from armored plant-eaters to swift, sharp-toothed hunters. Their reign ended abruptly about 66 million years ago, when a massive asteroid impact triggered the most famous mass extinction in Earth's history. Yet their story is far from a simple tale of vanished monsters, and the deeper you look, the stranger and more wonderful it becomes.
Despite the popular image of cold, sluggish reptiles, many dinosaurs were active, fast, and surprisingly bird-like. In fact, modern birds are living dinosaurs, descended directly from small feathered theropods, which means dinosaurs never truly disappeared at all. Fossil discoveries have revealed that numerous species, including some relatives of Tyrannosaurus rex, sported feathers. The word dinosaur, coined in 1842 by scientist Richard Owen, means terrible lizard, though dinosaurs were neither lizards nor always terrible. They walked with limbs held directly beneath their bodies, an upright posture that set them apart from sprawling reptiles and helped make them remarkably successful across the ancient world.
Some of the most familiar dinosaurs never actually met one another. Stegosaurus, with its iconic back plates, lived during the Jurassic and had already been extinct for tens of millions of years before Tyrannosaurus rex appeared in the late Cretaceous. That gap is larger than the time separating T. rex from us. Scientists study these animals through fossils, including bones, footprints, eggs, and even preserved skin impressions, piecing together how they moved, grew, and behaved. New species are still being named regularly around the globe, and each discovery reshapes our understanding. The age of dinosaurs remains one of the richest chapters in the long story of life.

Answer: Cretaceous and Paleogene. Non-avian dinosaurs died out at the Cretaceous-Paleogene boundary about 66 million years ago.
6. Which dinosaur's name means 'tyrant lizard king'?
Answer: Tyrannosaurus rex. The name Tyrannosaurus rex derives from Greek and Latin meaning tyrant lizard king.
