The study of fossils in different aged rocks show all of the following except :

Options

A. They probably died during the formation of that particular sediment
B. Some of them appears similar to modern organisms
C. life forms varied over time and certain forms were restricted to certain geological time spans
D. They do not represent extinct organisms

Answer

To solve the question regarding the study of fossils in different aged rocks, we will analyze each option provided and determine which statement is incorrect.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what the study of fossils in different aged rocks does not show. This means we need to identify the statement that is false regarding the information we can gather from fossils.

2. **Analyzing Each Option**:
- **Option 1**: "They probably died during the formation of that particular sediment."
- This statement is true. Fossils are formed from organisms that lived and died in the environment where the sediment was deposited.

- **Option 2**: "Some of them appear similar to modern organisms."
- This statement is also true. Fossils can show similarities to modern organisms, indicating evolutionary relationships.

- **Option 3**: "Life forms varied over time and certain forms were restricted to certain geological time spans."
- This statement is true as well. The fossil record shows that life forms have changed over time and some species existed only during specific geological periods.

- **Option 4**: "They do not represent extinct organisms."
- This statement is false. Fossils are primarily the remains of organisms that are no longer living, thus they do represent extinct organisms.

3. **Conclusion**: The correct answer is **Option 4** because it incorrectly states that fossils do not represent extinct organisms.

### Final Answer:
The study of fossils in different aged rocks shows all of the following except: **They do not represent extinct organisms.**
