[Rockhounds] The death of dinosaurs was all about the asteroid

[Dora Smith]

Common sense tells us it must have been about both the Deccan traps and 
the asteroid.

There's a two-part video on You Tube, more than two hours long, 
depicting what would happen if a similar asteroid struck in the exact 
same place in the present time.   Leaves one wondering how on earth 25% 
of life forms survived.   Maybe 99.99% of the life forms that survived 
were bacteria?  Only a few people survived, and only the most adaptable 
and lucky of them, and there was next to nothing to eat.

Doesn't seem like the Deccan traps were necessary, but they were there 
and must have created an environmental nightmare in their own right.   I 
think they went on for a long time, too.    Also, I think there's a good 
deal of evidence that something had already threatened the dinosaurs 
when the asteroid hit.
