1. I think it might have something to do with evolution and the environment changes. As time changes, people have learned more, discovered a lot. The cavemen, Java, Neanderthal, Heidelberg once live in caves which their appearances seem more like an ape. Same thing with the prehistoric dinosaurs and birds. I don't know for sure, but the clouds and sun probably did have something to do with extinction.
2. Scientists cannot be sure exactly how dinosaurs went extinct, but probably due to many factor including increace of volcanic activity, global warming or cooling, asteroid impact. The dinosaurs extinction is the most faous of many many extinctions that happened in the history of the earth. check out this site for more info: http://www.enchantedlearning.com/subjects/Geologictime.html I really like this site, its very interesting despite its poor aesthetics . I think birds bones have a similar density to dinosaur bones. They both have vascular canals in their bones for blood vessels. Dinosaurs were warm blooded.
