>From www.space.com, a story about large impact at mouth of present day Chesapeake Bay. Estimated date 35,000,000 B.C., or so. Havent heard of this one on list, although strictly speaking is not Dino related. Any funky extinction events correspond to it? http://www.space.com/news/langley_drilling_000728.html Cheers, M.J.
