Scientists have extracted intact bone marrow from the fossilized remains of 10-million-year-old frogs and salamanders.

The finding, detailed in the August issue of the journal Geology, is the first case of fossilized bone marrow ever to be discovered and only the second report of fossilized soft tissue. In June of 2005, scientists announced they had found preserved red blood cells from a Tyrannosaurus rex leg bone.

Preserved soft tissue could provide insight into the physiology of ancient beasts that can't be gleaned from their fossilized bones alone. If scientists could find bone marrow from dinosaurs, for example, it could help resolve the debate about whether the creatures were warm-blooded or not, McNamara said.

Pretty cool find.
I hope they discover some from dinos, so, as mentioned above, they can find out if dinosaurs were warm or cold blooded.
