Dinosaurs & Science

[Prince Cobra]

What do you believe led to their extinction? I know the asteroid causing it, but I assume their are other theories out there as well.

Well, I think the dinosaurs were quite resilient so a single factor could not bring to their extinction. I think the vulcanic activity, the poisonous sulphur fumes and the asteroid: they all brought about their exticntion. In fact, even that was not enough in relative terms since for a shord period after that the birds, a close relatives of the dinos, managed to dominate the world for a limited period of time. The mammals were faster to adapt to the new conditions. Why the mammals were thriving was the big question. I have always wondered if being a dominating species weakens your surviving ability or it has something to do with the egg shell...
