Answer

To answer the question about the origin, dominance, and extinction of dinosaurs, we can break it down into three main parts:

### Step 1: Origin of Dinosaurs
- Dinosaurs originated during the **Triassic period**, which is the first period of the **Mesozoic era**. This era is often referred to as the "Age of Dinosaurs."

### Step 2: Dominance of Dinosaurs
- Dinosaurs became the dominant terrestrial vertebrates during the **Jurassic period**, which is the second period of the Mesozoic era. This period saw a significant diversification and proliferation of dinosaur species.

### Step 3: Extinction of Dinosaurs
- Dinosaurs went extinct at the end of the **Cretaceous period**, which is the third and final period of the Mesozoic era. This mass extinction event is widely believed to have been caused by a combination of catastrophic events, including a meteor impact and volcanic activity.

### Conclusion
Putting this information together, we can summarize that dinosaurs originated in the **Triassic period**, became dominant during the **Jurassic period**, and went extinct at the end of the **Cretaceous period**.

### Final Answer
Dinosaurs were originated in the **Triassic period**, became dominant in the **Jurassic period**, and became extinct at the end of the **Cretaceous period**.
