New Dinosaur species found in Utah

[lovbyts]

Ive read about how small the nostrils where on some of these large creatures and lung capacity not the big. They say the due to the atmosphere and other natural phenomenon (no pollutants) that the earth had a lot higher O2 content so they didn't need to breath as much or have larger lungs like we do.

Put them on this planet right now they would probably die of second-hand smoke like instantly.
