Bones to pick: the marrow view

It seems that somebody kissed enough frogs to find a prince, with Maria McNamara of the Uni of Dublin finding more-or-less intact marrow in the bones of a frog dated at 10 million years old.

That’s an old frog, and it wasn’t exactly dropped in liquid nitrogen on Day One, either. It just goes to show that whatever you show, someone’s going to find a major exception to it one day.

Quoth Ms McNamara:

The find suggests that palaeontologists may have missed marrow residues inside many more intact fossils. “People never tend to look inside, because the bones are so valuable for science that you don't want to smash them up,” says McNamara.
