2. **Identifying the Paleozoic Era**: The Paleozoic Era is known to have several periods, including the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.

3. **Examining the Given Options**: The question provides four options: Triassic, Cambrian, Jurassic, and Cretaceous. We need to identify which of these belongs to the Paleozoic Era.

4. **Analyzing Each Option**:
- **Triassic**: This period is part of the Mesozoic Era, not the Paleozoic.

- **Jurassic**: This period is also part of the Mesozoic Era, following the Triassic.
- **Cretaceous**: This period is the last of the Mesozoic Era.

5. **Conclusion**: Since the Cambrian is the only option that belongs to the Paleozoic Era, it is the correct answer.
