Caitlan,
"But the [iridium-bearing K/T
boundary] clay bed was black, smelled
sulfurous, and had no fossils
except for fish bones. During the time interval
represented by this
'fish clay,' the healthy sea bottom had turned into a
lifeless,
stagnant, oxygen-starved graveyard, where dead fish slowly
rotted."
That's an
(admittedly singular) example of what I would consider odd.......where
are all the ammonite shells, larger -species bones
etc....
cheers, martin
I'm sure there's much discussion
about this in the archives. Just so much --
1. The animals that died in the
impact would have died anyway within 100 years or so. Now you try to tell 100
years and 100 days apart in a sediment.
