Super Cool Dinosaurs

TARDIS - Dinosaurs were an incredibly diverse group of reptiles that dominated Earth's terrestrial ecosystems for over 140 million years during the Mesozoic Era. Spanning from the late Triassic period until their sudden extinction at the end of the Cretaceous period, they evolved into an astonishing variety of shapes and sizes. This ranged from the massive, long-necked sauropods like Brachiosaurus—some of the largest land animals to ever live—to fierce, bipedal predators like Tyrannosaurus rex, and even small, agile hunters no bigger than a chicken. sonic Far from the sluggish, cold-blooded monsters of early scientific imagination, modern research reveals that many dinosaurs were active, warm-blooded, and highly social creatures, often sporting complex behaviors and vibrant displays of feathers. While a catastrophic asteroid impact ultimately ended the reign of the non-avian dinosaurs roughly 66 million years ago, their incredible legacy lives on today through their only surviving descendants: modern birds. gallifrey falls
