Were trilobites alive in the permian period?
Yes, trilobites were still present in the Permian, but at much lower numbers and diversity. Only the Order Proetida remained. The Permian ended with a mass extinction, and among the many groups which went extinct at the end of the Permian were the last trilobites. See Related Links below.
The largest extinction the world has ever known occurred at the end of which period?
The largest extinction event known is the Permian-Triassic Extinction Event, 250 million years ago. It is nicknamed "The Great Dying" in reference to how 96% of all known marine animals and 70% of all known terrestrial vertebrates at the time went extinct due to climatic changes because of volcanic eruptions and the formation of Pangaea.
What species of lemurs went extinct?
one major species was the extinct lemur. they've been extinct for minutes.
What might have caused the mass extinction at the end of the paleozoic era?
The mass extinction, known as the Permian extinction, affected both plants and animals on land and in the seas. Scientists do not know what catastrophic events caused the mass extinction, many kinds of organisms suddenly became extinct, as much as 90% of Marine species may have died out.
What influence did speciation have on Darwin's development of Natural Selection?
The influence of providing an explanatory mechanism for what was obvious to Darwin; species arose and species went extinct.
Why did trilobites become extinct?
The trilobites went extinct during the mass extinction at the end of the Permian period.

When did the dimetrodon went extinct?
the dimetrodon went extinct in the Permian Mass Extiction Event in 250 million years ago
What were some animal extinctions in the Permian period?
Many different organisms went extinct at the end of the Permian. Some of them include trilobites, conodonts, sea scorpions, and blastoids. Many other groups were nearly wiped out, with only a few species surviving. Brachiopods were decimated by the extinction event and never fully recovered as clams became more dominant.

What period in which the last ammonites became extinct?
Ammonites went extinct at the end of the Cretaceous Period.
When did the dinosaurs became extingt?
The last dinosaurs became extinct about 65 million years ago at the end of the Cretaceous period.
Why the huayangosaurus went extinct?
huayangosaurus went extinct in the K/T Mass Extinction in 65 million years ago with all Dinosaurs Went Extinct
What rhinos have gone extinct?
Extinct is an incomparative word. Things are either extinct or not, you cannot have degrees or levels of extinction. At present the rhinoceros is greatly endangered and may become extinct.
Where does extinction happen?
Extinction happens when an endangered species is completely wiped out by human activity or natural disaster for example:- the Ice Age when the mammoths and the other animals which went extinct at the same time
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.
Can you describe condition that makes it possible for a species to undergo adaptive radiation?
When the dinosaurs went extinct the mammals that were living alongside the dinosaurs underwent massive adaptive radiation. Large extinction events can give rise to niche openings for species that go through the extinction event.
