Thanks. Looks like the royal society link is the original work, but the nature editorial also mentions the same - it’s still possible we might have higher stability in other conditions (they only loooked at dna in bone samples). Not saying we will hold hope for dinosaur cloning, just that 521 years sounds too small.

DNA is stable, but still susceptible to hydrolysis. Water will eventually degrade it down to constitutive parts.
