Scientists in Ohio and Massachusetts have discovered that meat-eating dinosaurs like Tyrannosaurus rex had lungs similar to birds. This provides more evidence that dinosaurs are the ancestors of birds.

However, the short article doesn't say how the scientists figured this out. If anybody has more links, please share them!

Well I was just able to track down this article on Rueters that says

Claessens and Patrick O'Connor, of Ohio University's College of Osteopathic Medicine, compared dinosaur bones in museums in the United States, Germany and England with modern birds. They looked at how the skeleton related to the air system in areas such as the neck and chest.

I believe, they were able to draw conclusions about the dinos' lungs by looking at the blood vessel structures in their bones.

Our resident paleontologist, Kristi Curry Rogers, is out in the field right now, but when she gets back I will make sure to ask if these scientists studied any of the dinosaur bones that we have in our collection, here at the Science Museum of Minnesota.

Thats cool but did you know that people think that the t-rex might have been a skavanger becuase of its tiny arms. the bird thing is pretty awsome to becuase that gives us a little more information about evolution.

No matter what kind of poppycock they come out with they can never prove that dinasours and birds are the same
