Browsing: Dinosaurs
Dinosaurs were a diverse group of reptiles that dominated Earth’s terrestrial ecosystems for over 160 million years, from the Triassic through the Cretaceous period, until their sudden extinction around 66 million years ago. They ranged from towering carnivores like Tyrannosaurus rex to gentle giants like Brachiosaurus, as well as small, bird-like species that gave rise to modern birds. Paleontologists continue to uncover new fossils and use advanced technologies to learn more about their biology, behavior, evolution, and the mass extinction event that ended their reign.
