Re: Undersea Meteor Crater Found

Hi Dinolisters,

The smoking gun of the Jurassic/Cretaceous boundary? "150 million years ago"
sounds awfully close to several other impact craters from around that
boundary. Remnants of a comet shower?

Just goes to show how tough the dinos were. What would happen to our species
if a mile and a half of rock hit the sea? Wouldn't be as easy as "Deep
Impact" made it out to be - and that wasn't pretty.
