c and other simple amines and sulfur-containing molecules could stay trapped in the rock until released with excavation. Just because something's been dead for millions of years doesn't mean it can't smell like anything.

Actually, you *assume* that something's been dead for 'millions of years' such that it still smells like a cadaver even after fossilization.

There is obviously no way to test this since an experiment can't last for 'millions of years'.

The fact that putrescin is still present is evidence that these fossils *aren't* 'millions of years old', not evidence that there is some unknown condition that would preserve putrescin for 'millions of years'.

Actually it can be tested, is being tested, and will continue to be tested. Its as simple as taking a air sample, examining the matter that the oder is from and determining whether the odor is from the material of a cadaver or something other. Then you might question and explain the odor.

What, you mean the unknown condition of being sealed in solid rock?
