2. **Identifying the Geological Eras**: The options provided are Eocene, Jurassic, Carboniferous, and Oligocene. We need to analyze each of these periods to determine which one is associated with amphibians.

3. **Analyzing Each Option**:
- **Eocene**: This period is characterized by the emergence of hoofed animals such as horses and cows. Therefore, it is not the age of amphibians.
- **Jurassic**: This is known as the age of dinosaurs, which again does not relate to amphibians.
- **Carboniferous**: This period is significant because it is known for the dominance of amphibians. It is during this time that amphibians thrived and diversified.
- **Oligocene**: This period is marked by the presence of birds such as eagles and hawks, which are not related to amphibians.

4. **Conclusion**: Since the Carboniferous period is recognized for the dominance of amphibians, it is referred to as the "age of amphibians." Therefore, the correct answer is the Carboniferous period.

**Final Answer**: The age of amphibians is the Carboniferous.
