Jurassic Peck?

Yeah, I know. But it's late, OK...

This intrigues me. Scientists have found a way to isolate DNA from fossilized egg shells. Fossil egg shells are pretty common finds in deposits around the world, and have been extensively used for analyses like radiocarbon dating. Now, researchers may also be able to use them to create a DNA profile of extinct species.

One of the birds that's being examined is the the elephant bird, Aepyornis. The name is descriptive - Aepyornis was the largest bird that ever lived, reaching heights of 10 feet and weighing nearly a ton. They're looking at eggshells of another extinct giant, the moa, as well.

I know what you're thinking... I don't know the answer for certain, but I strongly suspect it's "No, we won't be able recreate elephant birds and moas." Fun to think about, though.
