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.

According to Cr and Mn isotopic analyses of KTB samples, the impactor was a
carbonaceous chondrite - see report at:

Yes, but it appears that comets are essentially carbonaceous chondrites

Hi Sterling -
I would imagine a lot of the cosmic osmium would have
been sequestered in the impact spherules. The KT
fossil meteorite seems to have been ignored by this
group, so
How would you determine the composition of what hit?
First, take samples from around the crater. Then

Hi, EP, List,
I think the method will prove valuable. Tho I know
little of the chemistry of osmium, they say that, once
vaporized, it goes
