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 does not occur During A Cenozoic era?
Several periods of mass extinction
How do you know a mass extinction actually did occur?
No evidence of the extinct lifeforms appears in the stratigraphic record immediately following the extinction event.
The deadliest of all mass extinctions which killed 95 percent of all living organisms was the?
Permian-Triassic extinction, 251 MYA (million years ago) in the Paleozoic era.
When was the last mass extinction?
The Cretaceous–Tertiary extinction event 65 million years ago was the last mass-extinction, and many believe that humans are causing a mass-extinction right now.
Why do you think most extinction's occur as background extinctions?
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
How did the coelophysis die off?
The better Q is "What was the cause of the triassic mass-Extinction?"

What are the extinction of animals in the very distant past?
There were five major extinction events in the past. They are called the Cretaceous-Tertiary (or K-T) extinction event, the late Devonian mass extinction, the Permian mass extinction, the Ordovician-Silurian mass extinction and the Triassic-Jurassic mass extinction event.
When did organisms suffer the largest mass extinction known?
The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
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 event occurred about 250 million years ago and caused about 90 of the species living in the ocean to become extinct?
The Permian-Triassic mass extinction, aka "the Great Dying", the single most devastating mass extinction known.
What are 3 reasons for mass extinction?
Mass extinction could occur due to climate change, an asteroid impact and even a volcanic eruption.

What does not occur During A Cenozoic era?
Several periods of mass extinction
When doe extinction occur?
Extinction of a single species can occur at any time if said species in hunted excessively, but mass extinction only occurs every 27 to 33 million years.
What were the 5 major extinction events in earth history?
They are the end-Ordovician extinction, end-Devonian extinction, end-Permian extinction, the Triassic extinction, end-Cretaceous extinction.
