Why is fossil record hard to interpret?

  Fossil is hard to interpret because the animals' or plants' are at least 10,000 years ago, so it is very hard to tell the shape or species or the animals' or plants' fossils.  In addition, the paleontologists always break the fossils to take the main shape out, so a lot of fossils do not have enough parts on them.  Getting a fossil also is hard since the paleontologists are getting the fossils under the heating sun and inside the ground.  On the other hand, interpreting the fossils also can become easier because some ants are helpers who collect the tiny pieces of fossils under the ground.  To sum up these reasons, interpreting the fossils is a hard job, and we need to appreciate the hard works of the paleontologists.
