Re: Precisely Dating The KT Boundary
Is the global Iridium layer unique? If so, I suggest "IL" as a substitute for
"K/T" to avoid future modifications to stratigraphic nomenclature. Or, if not
unique, but sufficiently unusual, then "IL1, 2, 3...". This assumes of course
that no forward-looking scientists are going to change the names of the
elements...

I thought "P" was for "Permian". Wouldn't it be the K/Pg boundary? (Or
why not just the M/C boundary?)
