What are 3 fun facts about the Triassic Period?
15 Triassic Period Facts The Triassic Period was the shortest period of the Mesozoic Era. The Triassic Period lasted roughly 50.6 million years. The Triassic Period occurred between 251.902 and 201.3 million years ago. The Triassic Period had three epochs, the Early Triassic, the Middle Triassic and the Late Triassic.
What major geologic events happened in the Triassic Period?
The start of the Triassic period (and the Mesozoic era) was a desolate time in Earth’s history. Something—a bout of violent volcanic eruptions, climate change, or perhaps a fatal run-in with a comet or asteroid—had triggered the extinction of more than 90 percent of Earth’s species.

What are 5 living things from the Triassic period?
Mosses and ferns survived in coastal regions. Spiders, scorpions, millipedes and centipedes survived, as well as the newer groups of beetles. The only new insect group of the Triassic was the grasshoppers.
What did Earth look like in the Triassic Period?
The environment during the Triassic was as varied as it is today, with large swathes of forests, dry deserts and open prairies. ‘The global effect of this supercontinent would have been a greatly enhanced seasonality in different parts of it.
Why did Triassic Period End?
Huge and widespread volcanic eruptions triggered the end-Triassic extinction. Some 200 million years ago, an increase in atmospheric CO2 caused acidification of the oceans and global warming that killed off 76 percent of marine and terrestrial species on Earth.
What major tectonic event begins in the Triassic?
At the beginning of the Triassic period, the land masses of the world were still bound together into the vast supercontinent known as Pangaea.
What is Cretaceous period known for?
The Cretaceous Period. The Cretaceous is usually noted for being the last portion of the “Age of Dinosaurs”, but that does not mean that new kinds of dinosaurs did not appear then. It is during the Cretaceous that the first ceratopsian and pachycepalosaurid dinosaurs appeared.

What major geologic events happened in the Triassic period?
What makes the Cretaceous Period unique?
The Cretaceous Period is biologically significant because it is a major part of the transition from the early life-forms of the Paleozoic Era to the advanced diversity of the current Cenozoic Era. For example, most if not all of the flowering plants (angiosperms) made their first appearance during the Cretaceous.
What major events happened in the Cretaceous?
Significant Cretaceous events
- First Flowering Plants. Angiosperms (flowering plants) appeared in the fossil record more than 100 million years ago during the Cretaceous Period.
- Rise of the Rocky Mountains.
- Cretaceous Interior Seaway.
- Mass Extinction.
