It’s interesting to see just how permeant digital memory has become in our every day lives. It’s like everytime I turn my head, I see something with a card slot or USB jack . I guess it makes sense though, considering how cheap memory has become lately…Gahhhh, who am I to complain. I can’t make it through a day without my R4 / R4i!(Posted using FPost for R4i Nintendo DS.)

Naruto, it’s not a mistake, there is increasing evidence that at least some dinosaurs were endotherms, my guess would be among the theropods which evolved the birds, nova has a neat episode about it online and this article mentions it. Jessica, good to see young people putting actual thought into things like this, but mammals did not contribute to the fall of dinosaurs. niches were saturated by dinosaurs and nothing was available for early mammals to exploit. recent evidence has been shown that mammals didn’t actually begin to diversify greatly and dominate until circa 45 MYA, 20 million years after the K-T extinction. I’m no expert, but personally, I think volcanism is more to blame for the extinction than a meteor. I’ve seen that newer dates of the alvarez meteor strike occurred up to a couple million years before the extinction. the deecan traps were unimaginably active compared to a standard eruption nowadays. If memory serves me right, volcanism is also a leading theory to the permian extinction 250 mya leading to the extinction of over 95 percent of all species. in general, i think when it comes to paleontology, scientists are too apt to fall for a single theory rather than explore the interaction of many causes.

Mesozoic period. Hot, atmosphere full of moisture and CO2 and other GHGs. What do you actually how was it warming? Perhaps +15C? At a world increase of +15C over today. That also means that a winter LOW temperature is still higher 15C than todays winter LOW. What was the LOW in the Mesozoic. At Antarctica it was land at the south pole. No Ice. Any Ice at the north pole, if any, is not on land. I suggest that more is think into why the poles (both) have dinosaurs (any other animals and FLORA). Then rewrite the article.

I found your article interesting but lacking one piece of information. What was the climate of these areas at the time of the dinosaur? For Naruto…
cold blooded-having a body temperature not internally regulated but approximately that of the environment.
warm blooded-able to maintain high and constant body temperature essentially independant of the surroundings.
These are the definitions you will find in the Merriam-Webster dictionary.

I think there is a mistake in this article. The mistake is at the second paragraph, on the last line. “growing understanding that they were not cold-blooded creatures.”, and I think the right one should be:”growing understanding that they were cold-blooded creatures.” The “not” shouldn’t be in that line. If I am wrong about this mistake, can someone correct me or explain to me my mistake. Thanks.

Thanks for science because it allows us to continue unearthing new evidence and learning more about the our history.
