Wide-eyed first graders are not the only ones fascinated by sauropods, particularly those outsize friends... Nothing in the dinosaur world was quite like the sauropods....

The Medico-chirurgical review and journal of practical medicine The respiratory system then, is more developed in birds than in mammalia — the nervous less. The mean temperature of the mammalia is 38°, 4 (10r F.), that of birds 42° 1 (108° F.) Compare next reptiles with fishes. |
Amphibians, reptiles, birds and mammals - living and extinct
Birds are, seemingly, not as adversely affected since their respiratory system (with its stiff lungs) is better able to cope with the shunting around of large quantities of air (birds do get killed by turbines, but predominantly by collision with the
