Meat-eating Dinosaur From Argentina Had Bird-like Breathing System
Science Daily ^ | Sep. 30, 2008

Posted on 09/30/2008 9:49:28 AM PDT by Soliton

The remains of a 30-foot-long predatory dinosaur discovered along the banks of Argentina's Rio Colorado is helping to unravel how birds evolved their unusual breathing system. University of Michigan paleontologist Jeffrey Wilson was part of the team that made the discovery, to be published Sept. 29 in the online journal Public Library of Science ONE and announced at a news conference in Mendoza, Argentina.

The discovery of this dinosaur builds on decades of paleontological research indicating that birds evolved from dinosaurs.

Birds have a breathing system that is unique among land animals. Instead of lungs that expand, birds have a system of bellows, or air sacs, which help pump air through the lungs. This novel feature is the reason birds can fly higher and faster than bats, which, like all mammals, expand their lungs in a less efficient breathing process.

My thoughts on evolution are evolving.

According to the dinosaur's childhood friend, it's true.

It’s fascinating how God created in modular patterns, in a manner that is constantly resistant to evolutionary interpretation. Here we have at first glance a correspondence between birds and dinosaurs in the manner in which air is transported throughout body tissues. But instead of being found in a small dinosaur in strata appropriate to being considered as a precursor to birds, it ends up being found on a huge 30’ long dinosaur that no one would consider a progenitor of the avian race! The trunk of the presumed evolutionary tree is missing, as always.

Finding lung tissue in dinosaur remains would not amount to doing evo-losers any big favors....

Common ancestor to both.

This is testable. Watch for future discoveries of older fossils of small critters that even you could consider a progenitor of both the avian race and this big guy.

How did birds evolve from dinosaurs when dinosaurs were all killed off simultaneously from the asteroid?

This is bunk.

Natural selection of course.

The birds were flying high up in the sky when the asteroid hit the ground. The ejecta did not reach the birds. When the ejecta settled to the ground, the birds landed on the ground.

Q.E.D.

Doesn't understand natural selection ping! You believe scientists about the asteroid, but not about evolution!? Praise Brahma!

My sentiments exactly.

Deep in the jungles of Chicago, the Obamosaurus leftensis shows adaptation to a breathing system. The archaic life form Wrightrodon mudslingis forages for grubs

No, not at all.. There were definently dinosaurs and definently killed off from the asteroid.

I’m merely pointing out that i think this particular piece of research linking birds and dinosaurs is bunk.

IMO no animal could have possibly evolved from dinosaurs.

The branching off of the bird line from the dinosaur line occurred many millions of years before the asteroid 65 million years ago. Dinosaurs were dominant for about 150 million years. More than twice the span of mammal dominance. Google archopterix for more info.

What blows my mind is why a scientic publication would perpetuate ignorance by speaking of a “man eating dinosaur”, given that the dinosaurs died off about 60 million years before the first hominids were alive.

“Man eating dinosaurs.” It’s past my bedtime. I misread the title which said Meat-eating dinosaurs. My bad.
