The study of fossils in different aed rocks shows all of the following except. :

Options

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

Answer

To answer the question regarding the study of fossils in different aged rocks and identify the statement that is incorrect, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Fossils**:
- Fossils are the preserved remains or traces of organisms that lived in the past. They provide valuable information about extinct organisms, including plants and animals.

2. **Analyze Each Statement**:
- **Statement A**: "They probably died during the formation of that particular sediment."
- This statement is correct. Fossils can indeed form from organisms that died and were buried in sediment, leading to their preservation.

- **Statement B**: "Some of them appear similar to modern organisms."
- This statement is also correct. Many fossils show similarities to modern organisms, indicating evolutionary relationships.

- **Statement C**: "Life forms varied over time and certain forms were restricted to certain geological time spans."
- This statement is correct as well. The fossil record shows that life forms have changed over geological time, with certain species existing only during specific eras.

- **Statement D**: "They don't represent extinct organisms."
- This statement is incorrect. Fossils are, by definition, the remains of extinct organisms. Thus, this statement contradicts the very definition of fossils.

3. **Identify the Exception**:
- Since we are looking for the statement that is not true regarding fossils, we can conclude that **Statement D** is the exception. Fossils do represent extinct organisms.

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