article_snippet: Genetic material has been extracted from the shells of ancient elephant bird eggs.
article_snippet: Genetic material has raised hopes that Genetic material may be possible to use cloning techniques to resurrect the extinct species.
article_snippet: By injecting Genetic material into the unfertilised eggs of other large flightless birds like the ostrich, it may be possible to recreate the elephant bird.
article_snippet: However, scientists face significant challenges that need to be overcome before this is possible.
article_snippet: Cloning birds is considered to be particularly challenging.
article_snippet: Extracting enough DNA from eggshells is also thought to be another limiting factor.
article_snippet: Scientists were recently able to extract DNA from a similar egg, raising hopes that it may be possible to bring the elephant bird back to life using cloning techniques.
article_snippet: Technically, you could extract DNA from a CT scan of the egg and if you have a very large ostrich you could re-create a form of an elephant bird. '
