A well preserved hand from the Megalapteryxalso known as a Moa. This flightless bird is known to stand 16 feet tall and lay basketball sized blueish green eggs. But it is no dinosaur, in fact it was roaming the North American continent as little as 500 years ago. So what happened 500 years ago that made them go extinct? It was written that Christopher Columbus was so taken by these creatures he ordered them all dead, And their eggs were collected and taken back as a gift to the queen. The population soon diminished and they all died. But perhaps with new science one day we can bring them back.
