An incorrectly matched options w.r.t. geological time period and corredponding horse fossil is

Options

A. Pleistocene - Equus
B. Miocene - Plioshippus
C. Oligocene - Mesohippus
D. Oligocene - Miohippus

Answer

To solve the question of identifying the incorrectly matched option with respect to geological time periods and corresponding horse fossils, we will analyze each option step-by-step.

### Step-by-Step Solution:

1. **Identify the Options**:
- Pleistocene - Equus
- Miocene - Phyllohippus
- Oligocene - Mesohippus
- Oligocene - Miohippus

2. **Evaluate Each Option**:
- **Pleistocene - Equus**:
- Equus is indeed the genus that includes modern horses and existed during the Pleistocene epoch.
- **Match Status**: Correct.

- **Miocene - Phyllohippus**:
- Phyllohippus is not associated with the Miocene epoch; it actually existed during the Pleistocene. The horse that existed in the Miocene is known as Merikippus.
- **Match Status**: Incorrect.

- **Oligocene - Mesohippus**:
- Mesohippus is a genus of horse that did exist during the Oligocene epoch.
- **Match Status**: Correct.

- **Oligocene - Miohippus**:
- Miohippus is also a horse that existed during the Oligocene epoch, and it is often associated with Mesohippus.
- **Match Status**: Correct.

3. **Conclusion**:
- The only incorrect match is **Miocene - Phyllohippus**. Therefore, this is the answer to the question.

### Final Answer:
The incorrectly matched option with respect to geological time period and corresponding horse fossil is **Miocene - Phyllohippus**.
