The August issue of the journal Geology has an article on soft tissue found in 10 Ma (10 Million years old) amphibians. Adult salamanders of the genus Triton were found to have preserved organic tissue including highly decay-prone bone marrow. While the bone marrow maintained some original color and texture, it is unlikely that any DNA has been preserved making a Jurrasic Park for extinct salamander unlikely, at least, within this specimen. Other fossilized specimens may contain preserved organic material much more often than once believed.
