Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

          Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents. Life’s transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.
          What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on mega fossils-relatively large specimens of essentially whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive mega fossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that feed on the plants, and lastly by animals that preyed on the plant-eaters. Moreover, the mega fossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago.
          Recently, however, paleontologists have been taking a closer look at the sediments below this Silurian-Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rocks in an acid bath. The technique has uncovered new evidence form sediments that were deposited near the shores of the ancient oceans- plant microfossils and microscopic pieces of small animals. In many instances the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of them fossils consist of the organic remains of the organism.
          These newly discovered fossils have not only revealed the existence of previously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our views about the nature of the early plant and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms

What can be inferred from the passage about the fossils mentioned in the third paragraph?

A. They have not been helpful in understanding the evolution of terrestrial life

B. They were found in approximately the same numbers as vascular plant fossils

C. They are older than the mega fossils.

D. They consist of modern life-forms

What are fossils?
  Fossils are parts of animals that died a very long time ago .you can find fossils in rocks.you can see the shape of the animal .some fossils are more than 500 millions years old.
 
Why are fossils important?
Fossils tell us about the past. We can learn about types of rocks and we can learn about animals that lived a very long time ago.

Where can you find  fossils?
You can find fossils in many places. 
You can find them on mountains and in lakes.You can find them in rivers and on beaches. You can find them under the ground , too.
 
How can i see a fossil?
You can visit museum to look at fossils, or you can buy them in special fossils stores. You  can also look for fossils on the beach . Sometimes, you can see them on the sand or in the rocks.

This is a fossils of an ammonite. These animals lived in the sea about 400 million years ago. Today, you can find these fossils on the beaches in England.

This is a fossils of a wale. Scientist found it in the Western Desert  in Egypt. Millions of years ago the Western Desert was a sea.
