**Step-by-Step Solution:**

1. **Understanding Archaeopteryx**: Archaeopteryx is a significant fossil that exhibits characteristics of both reptiles and birds. It is often referred to as a transitional fossil, which means it provides evidence of the evolutionary link between these two groups.

2. **Identifying Reptilian Characteristics**:
- **Tooth Beak**: Archaeopteryx has a beak that contains teeth, which is a characteristic feature of reptiles. Modern birds do not have teeth, making this a clear indication of its reptilian ancestry.
- **Winged Claw**: It possesses claws on its wings, another trait associated with reptiles. This feature indicates that it had adaptations for climbing or grasping, similar to some reptiles.

3. **Identifying Avian Characteristics**:
- **Airfoil Wing**: The wings of Archaeopteryx are structured in a way that resembles the wings of modern birds, specifically with counter feathers that help in flight. This is a clear avian characteristic.
- **Long Tail with Many Vertebrae**: Archaeopteryx has a long tail that consists of several vertebrae, which is a trait seen in reptiles. In contrast, modern birds have a much shorter tail.

4. **Conclusion**: Based on the characteristics identified, Archaeopteryx shows features that are indicative of both reptiles and birds. Therefore, the correct answer to the question is that Archaeopteryx exhibits characters of both reptiles and birds.

**Final Answer**: Archaeopteryx shows the characters of reptiles and birds.
