Dinosaurs were a diverse group of reptiles that dominated the Earth during the Mesozoic Era (about 252 to 66 million years ago). They varied greatly in size, from tiny, bird-like creatures to massive, long-necked giants. Dinosaurs are classified mainly into two groups:

Saurischia ("lizard-hipped"): This group includes the meat-eating theropods (like T. rex) and the plant-eating sauropodomorphs (like Brachiosaurus).
Ornithischia ("bird-hipped"): These were mostly herbivores, including dinosaurs like Triceratops and Stegosaurus.

Dinosaurs lived in various environments, from dense forests to arid plains. Most went extinct about 66 million years ago due to a mass extinction event, likely caused by an asteroid impact. However, birds are considered their modern descendants, making dinosaurs a part of Earth's ongoing natural history.
