Which of the following is a correct match between period and its associated event?

Options

A. Permian (Period) Age of inverterbrates (Event)
B. Cambrian (Period) Age of vertebrates (Event)
C. Triassic (Period) Radiation of mammals ( Event)
D. Devonian (Period) Age of fishes (Event)

Answer

To answer the question regarding the correct match between geological periods and their associated events, we can analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Geological Periods and Events:**
- We need to look at the geological periods mentioned: Permian, Cambrian, Triassic, and Devonian.
- We also need to identify the events associated with each period as mentioned in the question.

2. **Analyze Each Period:**
- **Permian Period:**
- The statement claims it is associated with the "age of invertebrates."
- This is incorrect. The Permian period is known for the origin of mammal-like reptiles, not invertebrates.

- **Cambrian Period:**
- The statement claims it is associated with the "age of vertebrates."
- This is also incorrect. The Cambrian period is known as the "age of trilobites," which are invertebrates, not vertebrates.

- **Triassic Period:**
- The statement claims it is associated with the "radiation of mammals."
- This is misleading. The Triassic period is known for the origin of the first oviparous mammals (prototherians), but it is not primarily recognized for the radiation of mammals.

- **Devonian Period:**
- The statement claims it is associated with the "age of fishes."
- This is correct. The Devonian period is indeed known as the "age of fishes," and it is significant for the evolution of various fish species, including sharks.

3. **Conclusion:**
- The only correct match between the period and its associated event is the **Devonian Period** with the **age of fishes**.

### Final Answer:
The correct match between the period and its associated event is the **Devonian Period - Age of Fishes**.
