Another interesting article. A civil war naval ship sank in 1862. Two victims were discovered. The first was discovered in 2002. They were able to succesfully obtain dna from both victims, despite their being in the ocean for well over 100 years. Articles indicate dna was obtained from both a leg bone and the victims teeth. Warning graphic images (skeletal remains) at link: http://www.civilwarnews.com/archive/articles/2011/may/monitorcrew-051102.html This is the first I have seen with regards to succesfully obtaining dna on remains which have been submerged in the ocean for many years. In this case well over 100 years. In the event the speciman found on the beach in San Mateo county in 2006 had been submerged in water for any length of time, this article indicates dna can still be succesfully obtained.
