As you should...
After reading the Firestone book, I was thoroughly convinced. Now there is this very nearly irrefutable evidence of an impact which will open up many minds to such events. They have happened. They may happen in the future.
I remember a story about geologists or archaeologists doing core samples off the western Florida coast and pulling up the remains of a charred pine forest, with some of the debris so well preserved you could still smell the sap in the wood. Seems that the dating on this wood was close to the impact period. Do you remember this article?
If it was published in the past ten or so years, I’m sure blam posted it on FR. :’)
