Dinosaurs 'shrank' regularly to become birds

14 posts in this topic

Huge meat-eating, land-living dinosaurs evolved into birds by constantly shrinking for over 50 million years, scientists have revealed.

Theropods shrunk 12 times from 163kg (25st 9lb) to 0.8kg (1.8lb), before becoming modern birds.

The researchers found theropods were the only dinosaurs to get continuously smaller.

no ****, the raptors were the clue. I knew it was theropods because i used have dinosaur CD ROM which explained how raptors and other meat eaters shrunk and became bird like and this was in 1997-98!

Birds came from one species of dinosaur that wasn't very big anyway.

Yes, the idea that dinosaurs are the ancestors of birds has been around for many years. I think the difference is now there is much stronger evidence with more fossils uncovered, allowing a much clearer and tighter story to be described.

Wow that's amazing!

I just saw an emu that was making a drumming sound with lots of bass to it and you could feel it 50 yards away. Imagine what a T-Rex would sound like? I think the more bird-like Rex is far more frightening than a reptile roaring one. Something very unerving about giant birds.

Well ... I think it more accurate to say that their prey of the day moved in herds ~
