Triassic Period

The Triassic period is the first period of the Mesozoic era, lasting from approximately 251 to 201 million years ago. It is known for being a time of significant change and evolution in the Earth's history.

Geology

During the Triassic period, the Earth's landmasses were still joined together as the supercontinent Pangaea. The climate was generally warm and arid, with vast deserts covering large portions of the land.

Life Forms

The Triassic period saw the emergence of a wide variety of life forms, including early dinosaurs, mammals, and reptiles. This was a time of great diversity and experimentation in the evolutionary history of life on Earth.

Extinction Events

Toward the end of the Triassic period, there was a significant extinction event that marked the end of many marine and terrestrial species. This paved the way for the rise of new species in the subsequent Jurassic period.
