Scientists Found Out Why T-Rex Had Such Small Arms

For as long as I can remember, dinosaurs have felt like unfinished puzzles. The tiny arms of T. rex, the rumor of dinosaurs with two brains, the question of how a creature that big ever slept or sounded, they all linger because the fossils never tell the whole story at once. What I love about these mysteries is that they remind us how alive dinosaurs still are in science today. Every scar on a bone, every sleeping fossil, every frozen nursery in the Arctic feels like a quiet message from deep time, waiting for us to finally notice what we were missing. 0:00 Intro 0:24 Why did the T-Rex have such small arms? 8:40 Did Dinosaurs Have Two Brains? 13:42 How Did Dinosaurs Sleep? 19:17 What did the T-Rex Sound Like? 25:30 The Secret Dinosaurs of the Snow Uncover the mysteries of Earth’s most incredible prehistoric beasts! https://www.youtube.com/playlist?list=PLdLDHoLUjkJJVTDC92MDB-afu-u3w_9eJ Merch and much more about Origins Explained - you can also leave a video topic idea for us here: https://linktr.ee/originsexplained #trex #dinosaurs #tyrannosaurus
