What if the decay does not follow an exponential law? For example a power law?
Here's an interesting quote from the wikipedia article on ancient DNA [1]
"Researchers in 2016 measured chloroplast DNA in marine sediment cores, and found diatom DNA dating back to 1.4 million years. This DNA had a half-life significantly longer than previous research, of up to 15,000 years. Kirkpatrick's team also found that DNA only decayed along a half-life rate until about 100 thousand years, at which point it followed a slower, power-law decay rate"

- perl4ever 6y agoI mean, you're looking at figure 3 and the description thereof, but that seems to be a relative amount of DNA. I'd consider figure 1 instead. It appears that the half life is about 200,000 years for site U1343. At that rate, you still wouldn't have any dino DNA left even if the whole universe was made of it.
