There is no clear evidence to the extinction of the trilobites. However recent studies have shown regressive events in the early Cambrian period in the biostratifigraphic by the severe disruption in shallow water benthos in the biotic diversity by the fine alteration of clay and organic rich laminae calcite enriched by pyrite and elements typical of anoxic conditions of water.
The failure in the symbiotic relation with parasites is also a factor to extinction of the trilobites.
Just one final note:
The trilobites were extinct only in the largest mass extinction, in the end of the Permian period.

What factors led to allosuarus extinction?
That is unknown.
Why did trilobites become extinct?
The trilobites went extinct during the mass extinction at the end of the Permian period.
What period is sometimes called the golden age of trilobites?
Trilobites, amphibians, and many other species of animals became extinct in the Permian-Triassic extinction. This event happened over 250 million years ago.
What species went extinct in the permian extinction?
All of the Trilobites, Pelycosaurs, Gorgonopsians, Dimetrodon, Edaphosaurus, Pariesaurs, most of the ammonites, amphibians, and jawless fish, plus many more.
What is tribhites?
Trilobites are an extinct group of arthropods. They had exoskeletons, legs, and antennae. Trilobites existed from about 525 billion years ago during the Cambrian until they died out 250 million years ago, during the Permian Extinction, which wiped out about 99% of species. See the related links to learn more about trilobites.
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.
What a sentence for extinction?
It is believed that a meteor strike led to the extinction of dinosaurs
What time period was the creature trilobite in?
Trilobites originated during the Cambrian era, flourished through the Paleozoic era, declined during the Devonian era, and finally became extinct in the Permean mass extinction event. In total there were live trilobites on the earth for about 290 million years.
What is the primary hypothesis for the extinction of large mammals such as mammoth?
The primary hypothesis is that they were led to extinction by hunting by humans.
When was The Trilobites created?
The Trilobites was created in 1984.
Is their a chance that coon hunting can effect the extinction of raccoons?
Regulated hunting has NEVER led to the extinction of any species.
Why are trilobites not a powerful tool in the to discredit evolution?
Because they are powerful evidence for the Theory of Evolution. There are thousands to millions of species of trilobites. Some look like pillbugs to ones that walking pincushions. The range of trilobites grow tremendously with the fossil record. As the Cambrian Period advances the diversity of trilobites grows to massive levels. Plus they are among the oldest fossils found, about 500 million years old. They ebb and flow with current accepted extinction events too, rather than with the proposed theories presented by Creationists. It is more interesting to look at trilobites from why they support evolution. Science is about gaining support for a theory, not disproving.
