Question: how did the dinosoars go extinct

I do not really know why dinosaurs went extint. I think it’s a myth. I would love to know.

Of course they are extinct! There are some species of dinosaurs that are the ancestors of modern day bird species, but dinosaurs as a group of animals are extinct. The strongest theory at the moment is a large meteor hitting the Yucatan peninsula in Mexico around 66 million years ago,
This would have changed the atmosphere and prevented many plants from growing, causing mass starvation. Some of them would have also been killed by the direct impact of the meteor as well as in the tsunamis that were set off and circled the globe.

I was asked to have a look at this question by a moderator
looking at the fossil record, it can be shown that a t-rex is further away in all respects (physiologically and in phylogenetic distance (ie, time)) from a stegosaurus, and closer in both respects to modern day birds
this leads to the conclusion that dinosaurs didn’t go extinct, they became birds!
this comic illustrates and explains it brilliantly: http://www.xkcd.com/1211/

I think the dinosaurs went extinct by both a meteorite and a volcaninc eruption, but most likely to be a meteorite. =)

are there any still alive
what is your favorite endangered animal and, if you had the chance, would you save the species
Is the water I've been drinking today been drunk by some dinosaur?
