Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Dinausors weren't self-sustaining, it was a evolving taxon that lasted a very long time, but individual species weren't necessarily longer lived that most mammalian species. And when they finally disappeared - well, depending on what you call dinosaurs, birds are all dinosaurs - they were already on the decline. And it probably wasn't an external event as much as one of the regularly scheduled, biosphere cleaning massive volcanic activity, which apparently are also linked to many other mass extinction events - the main exception being the human-caused one happening right now.

(and since it might interest Bruce, it seems only question marks on a comment subject aren't accepted...)
