Re: Theories on the extinction of dinosaurs

I thought volcanic eruptions produced carbon dioxide, not oxygen... at least 
that's what my
geo textbook says... maybe the (relatively) sudden rise in carbon dioxide from 
the Traps,
then the sudden spike in oxygen from the impact was too much for the ecosystem 
to sustain.

On a side note... our chem prof mixed hydrogen and oxygen in class and it made 
a fireball
that rocked the entire lecture hall... and that was only a balloon full!  The 
amount of
energy released when several cubic miles of seawater's worth of those two 
elements combined
is beyond my comprehension...

Just a few thoughts...
