A dinosaur is a type of reptile that lived during the Mesozoic Era, which is divided into three periods: the Triassic, Jurassic, and Cretaceous. This era spanned from approximately 252 to 66 million years ago, during which dinosaurs thrived and diversified into various species. They are characterized by their unique skeletal structures and adaptations that allowed them to inhabit a wide range of environments. The Mesozoic Era ended with a mass extinction event that led to the demise of most dinosaur species.
The fastest dinosaur that ever lived was the cheetah-sized dinosaur called the Compsognathus.
The dinosaur that lived the longest was the Brachiosaurus, which lived around 150 million years ago during the Jurassic period.
The fastest dinosaur that ever lived was the cheetah-like dinosaur called the Dromiceiomimus, which could run up to speeds of 60 miles per hour.
