Today
there are some animals which look very much like some of the ancient
animals. So by studying them, scientists can have some idea of life.
No one can be completely sure how prehistoric animals lived. But luckily
there are creatures in the world on earth millions and millions of
years ago.
Coelacanths
:
In
Indian Ocean lives a fish that not only looks like pre-historic fish,
it is one! Fish called coelacanths lived in the ocean
for many millions of years. Scientists thought they had died out about
50 million years ago. Then in 1938 some fishermen caught a strange
- looking fish off the coast of South Africa. Scientists were
amazed to see that it was a coelacanth. The coelacanths are much like
their prehistoric ancestors of many millions of years ago , except
they are bigger. Their bodies are blue-ish-grey and covered with rough,
heavy scales. They eat small fish.
Moderates
:
The
first elephant-like animals, the moderates, had neither trunk nor
tusks. But over millions of years different kinds of elephants
developed. Today there are only two kinds of elephants on earth: Asian elephants
with small ears, and the bigger African elephants with large
flapping ears.
