Hi Sterling, all -

>From the article:

"Another possibility is that the impacting objects
were comets rather than asteroids, and contained much
less osmium to begin with. But chemical traces of
the impactors left behind in rocks and reported in
previous studies suggest otherwise."

The last I heard, the impactor was "carbonaceous
chondrite", i.l. "comet", and K-T fossil meteorite
showed that. Has this changed?
