Anything to support it? Warmbloodedness is neat in colder environments sure, but birds still kick ass, and dinos were pretty much big birds.

Generally accepted that the meteor impact finished off the dinosaurs, but for thousands of years prior the dinosaurs had been in decline possibly due to change in atmospheric oxygen or climatic change.

Dinosaurs were likely larger due to increased amount of oxygen in the atmosphere. Insects and other animals were much larger back then as well and their decrease in size correlates to a decrease in atmospheric oxygen.

>> No.3138436

>>3138301
I believe the prevailing theory holds that millions of years before the dinosaurs, the atmosphere was mostly methane and stromatolite colonies had synthesized this methane into oxygen, resulting in the cambrian explosion. Atmospheric oxygen seems to have remained relatively high during the time of the dinosaurs. Not really sure why it declined in the first place though.

I would say The Flood, but current thinking suggests dinosaurs are actually demons and so some of them could have arrived after Noah. So angels killed them maybe, some of them at least.

>> No.3138470

>>3138454
Pretty much.
Atmospheric oxygen was much higher during the time the dinosaurs lived. Not sure if they could live today but if they could they might be strained for breath or something. Hard to say with any sort of certainty.
At least the very large dinosaurs. Things like raptors would probably be able to survive.

God killed all the dinosaurs when they started eating each other. "Thou shall not kill." Before that they lived in the Garden of Eden and they just ate plants. So God flooded the world and killed all the dinosaurs. He told Noah not to let any dinosaurs on the Ark.

That's like saying the finches which live now and the finches which lived 100000 years ago that branched out are related but not the same.
Everything is the same, just branched out a bit, suiting the habitat.
I guess it's just semantics though, what you personally want to think as related or the same.

Well, you're wrong. You can talk all you want about what the classification system SHOULD be, but it's not how the classification system IS. Monkeys are primates that are not apes or prosimians. Humans are apes, so they can't be prosimians. You can say we're simiiformes, but you can't say we're monkeys.

At my university (University of Toronto) the Biology and Anthropology departments are teaching the new standard. I imagine the only reason the standard hasn't been updated everywhere is the cost of printing new textbooks (most profs here have written their own) and laymen being confused for a while.

They were awesome, and they only died because of a cosmic event they had no control over. In the future, we should bring these mighty beasts back, find them a planet to settle, and give them a second chance.

>> No.3140201

hurr

/sci/ thinks dinosaurs were larger because higher oxygen content in the atmosphere.

/sci/ thinks the Mesozoic actually had higher oxygen content.

c'mon guys, by now we know that it was actually higher CO2 content that drove increased plant productivity leading to nutrient dilution driving increased generalized herbivore size resulting in an increase in predator size.

this is what happens when you jackasses chase off every geologist and biologist that happens by your shitty board. fucking morons.
