Isn't this mostly due to the huge redundancy? All trillion cells of that mammoth carried duplicates of the encoded information, and recovering that information involves a lot of matching incomplete degraded strings against each other. The estimated half-life for DNA is apparently 521 years [1] (still quite a bit longer than 50 years).
