Dinosaur:
A noun referring to any of a group of extinct reptiles that lived millions of years ago during the Mesozoic Era, typically large and terrestrial. Dinosaurs are believed to have first appeared approximately 230 million years ago and became the dominant terrestrial vertebrates for over 160 million years. They were characterized by their bipedal or quadrupedal stance, with most having scales or feathers covering their bodies. Dinosaurs varied in size, with some being as small as chickens, while others were enormous, such as the long-necked Brachiosaurus.
These ancient creatures were classified into two main groups based on their hip structure - the Saurischia, which included the theropods like Tyrannosaurus rex and the long-necked sauropodomorphs like Brachiosaurus, and the Ornithischia, which comprised of herbivorous dinosaurs such as Triceratops and Stegosaurus. Dinosaurs exhibited diverse adaptations ranging from sharp teeth and claws for hunting, elaborate horns for defense, and complex anatomical features for communication and display.
The term "dinosaur" is derived from the Greek words "deinos," meaning terrible or fearsome, and "sauros," which means lizard. Although they went extinct approximately 66 million years ago, dinosaurs continue to captivate the imagination of people around the world and are studied extensively through paleontology, providing valuable insights into Earth's prehistoric past.
