A headline crawling across the top of my screen on the BBC Ticker caught my eye:
Fossil frogs yield ‘soft tissues’

Normally, when a creature is fossilized, the soft tissues are destroyed and you’re left with the fossilized bones. If you’re lucky, you can see where the soft tissues were and that’s about it. Well, it appears that about 10 million years ago, some frogs and salamanders were preserved in some swamps in northeastern Spain. However, unlike every other fossilized creature that’s been found to-date, some of these have both types of bone marrow preserved.

Needless to say, this opens up new possibilities for research into the ancestors of animals that are still around today.
