How did the triassic-jurassic extinction event create diversification in dinosaurs?
Dinosaurs first appeared in the middle of the Triassic period. The extinction during the Triassic-Jurassic periods allowed dinosaurs to grow to mammoth proportions.
What signaled the end of the Paleozoic Era?
The Permian- Triassic extinction event was the greatest extinction on Earth. 95% of all organisms died during this time period, signaling the beginning of the Triassic.
What are mass extinction and background extinction different?
Mass extinction - More than 50% of the population went extinct in a short period of time.Background extinction - An average rate of extinction occurred during a given time period.
When did the lystrosaurus went extinct?
Lystrosaurus went extinct at the end of triassic in the triassic-jurrasic extintion event at 200 million years ago during the break up of the supercontinent pangea with the alongside with the armoured archosaurs and some achosaurs and the dinosaurs take over the world in the early jurrasic.
What Era did dinosaurs live in?
The dinosaurs lived in the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods. The first dinosaurs appeared in the late Triassic and went extinct at the end of the Cretaceous.
What is Permian?
The Permian was the last period of the Paleozoic Era, spanning 299-351 million years ago. It was a time during which reptiles diversified. It ended with the Permian-Triassic extinction event, the largest mass extinction in Earth's history.
Why did trilobites become extinct?

During extinction an instrumental behavior may initially increase as the result of what?
During extinction of a species, their predators will be left looking for a new food source. Also, the food of the extinct animal will no longer be as controlled.
When did the triassic period take place?
The Triassic was from about 225 million to 190 million years ago. It is the first period of the Mesozoic ("middle life") Era.The Triassic Period is most commonly believed to have begun 251 million years ago and lasted until 199.6 million years ago.
Why did the microraptor become extinct?
The microraptor existed during the early Cretaceous period. It became extinct following the KT extinction event, which wiped out the majority of life on earth.
How does the background rate of extinction differ from mass extinctions?
The background rate of extinction is much smaller than those that occur during a mass extinction. For example, carnotaurus sastrei went extinct during the mid-Cretaceous, when only a handful of dinosaurs went extinct. On the other hand, 65 million years ago, all dinosaurs went extinct during the K/T mass extinction event.
What traits did the organisms have that made them extinct during the K-T extinction?
They could not hibernate or go very long without resources.
