What caused the Devonian mass extinction?
No one knows for sure. Some people believe that an asteroid earlier in time hit Earth and caused massive climate change that killed off reptiles, but spared dinosaurs. Others believe that it was simply climate change.
What are facts about the devonian period?
The Devonian Period is a part of the Paleozoic Era, which covers the time from 541 to 252.17 million years ago. It began with the Cambrian explosion, in which most phyla of life began, and ended with the mass extinction called the Permian-Triassic extinction event.
Relationship between extinct and mass extinction?
Mass extinction is when many animals go extinct within a short period of time caused by the same variables/factors leading to the mass extinction.
What geological events happened in the Cambrian time?
the mass extinction
How was the Triassic period ended?
The Devonian time period ended because of a mass extinction of several species of fish, amphibians and other types of reptiles.
What unit of geologic time followed the mass extinction of dinosaurs?
Jurassic period
What time period was considered The Age of Fishes?
The Devonian Period
What term describes development of new species and a mass extinction?
Evolution is the term that describes development of new species and mass extinction. Over time all living thing have evolved.
Itmay have crashed into earth and caused a mass extinction a long time ago?
asteroid
Is the Jurassic period a geologic time that followed the mass extinction of dinosaurs?
No. The Jurassic was in the middle of the dinosaurs' reign on Earth. The time period after the extinction of the dinosaurs is referred to as the Paleogene or the Tertiary.
