Scientists Are Studying New Zealand's Extinct Moa Bird

It seems we can study what animals looked like even though they are extinct. Australian and New Zealand scientists are studying prehistoric feathers to find out what birds were like. DNA has been obtained from the extinct Moa bird of New Zealand from feathers 2,500 years old. Moa are thought to have been still alive 1200 years ago It was 8 feet tall and could not fly. Material has been gleaned from three types of Moa: the stout legged; the heavy footed; and the upland Moa.

Somehow they have worked out that wing feathers had speckled white tips. This was to camouflage the bird from predators. The very large Haast eagle once existed that preyed on them. It is claimed that because the plumage of other flightless NZ birds is dull with speckled tips this idea is valid.

The scientists plan to get feathers from the end of the quill and further down the quill to compare coloration. It is hoped the findings will enable researchers to correctly reconstruct life-like models of extinct birds.

New Prehistoric Crocodiles Found

A new type of crocodile now extinct has been found in northern Africa. It had three sets of fangs like wild boar tusks for killing other animals. Another kind of crocodile was found nearby. This one used a flat, wide snout to catch fish. A third species of crocodile also located close by was only three feet long. This had "buckteeth" for eating plants. It was a rich find with two other known kinds of crocodile being dug up there.

The National Geographic Society sponsored the successful project. The new crocodiles show that the region had unique animals 100 million years ago. much different than in surrounding regions. These reptiles could run along at quite a fast pace then dive into the water and swim off. Unlike modern crocodiles which have legs on the side of their bodies these had longer legs set underneath. Luckily there were no people around for them to chase and eat.

The three new species are as follows:

1) BoarCroc (Kaprosuchus saharicus) 20 feet in length with three pairs of fangs sticking out of the side of their mouths like a warthog.

2) PancakeCroc (Laganosuchus thaumastos) again 20 feet long with shorter legs, laid in wait for fish grasping them with spiked teeth set in flat wide jaws in a head 3 feet long.

3) RatCroc (Araripesuchus rattoides) 3 feet from nose to tail, had buckteeth and dug for plants and grubs.
