Hi Marco:

The short lived isotopes decayed 4.5 - 4.6 or so billion years ago,
and only warmed the acreeted asteroid at that time. They are but a
distant memory when the meteorite falls here on earth today.

As for hot rocks. I found Buzzard coulee specimens in the spring time
2009. The ones that were exposed to the sun, were nice and warm,
almost hot, when we picked them up. : )
