You will not be expecting to find the fish skeleton in the Sahara Desert in Africa. But the scientists managed to find him there.
- Long ago the Sahara Desert is probably the ocean water. If that estimate is correct, it must be fish bones left behind when water dries up. But before the water dries up, there is something that has happened. In the past there may be a garden area with river and pasture in the area where the desert are now. The paintings found on cave walls in the desert shows that the animal may have lived there.
- Years later, the rivers were dry. Similarly grass. And the first place might be the ocean and then into the garden now is the most extensive deserts in the world.
