Which period is the second period of the Mesozoic Era?

Explanation:
Think about the timeline of the Mesozoic: Triassic, then Jurassic, then Cretaceous. The Permian sits earlier, as part of the Paleozoic era. The second period in that sequence is the Jurassic, which comes after the Triassic and before the Cretaceous. This order is how geologists organize the era, and the Jurassic is the period known for major dinosaur diversification—situating it neatly between Triassic beginnings and Cretaceous developments.
