The last of the trilobites disappeared in the mass extinction at the end of the Permian about 250 million years ago.

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.
No, trilobites are extinct marine arthropods that lived from the early Cambrian period to the end of the Permian period, around 520 to 250 million years ago. There are no living trilobites today.
During the Permian extinction, numerous species went extinct, including nearly 96% of marine species and around 70% of terrestrial vertebrate species. Some of the affected groups were trilobites, blastoids, amphibians, and early synapsids.
No, lions have a conservation status of "Vulnerable", but they are not extinct.
Trilobites existed for about 270 million years, from the Early Cambrian period to the end of the Permian period, before becoming extinct around 250 million years ago. Each species had its own lifespan, but on average, trilobites lived for a few years to several decades, depending on the species and environmental conditions.
Trilobites became extinct about 250 million years ago, in the Mesozoic Era.
The trilobites went extinct during the mass extinction at the end of the Permian period.
Trilobites are extinct but they were marine animals.
Trilobites have been extinct for a long time; there are none left for us to take care of.
The Trilobites.
Trilobites lived for 280 million years before they became extinct, from the Cambrian to the Permian.
If you mean trilobites, they have been extinct for millions of years.
You don't. Trilobites are extinct and are only found as fossils.
Scientists believe that trilobites reproduced sexually. These prehistoric and extinct creatures were a type of arthropod that probably laid eggs. Trilobites lived about 250 million years ago.

First it is trilobites and trilobites are all extinct but their modern relative are the horseshoe crab, lobster and some other crabs
Trilobites, and eurypterids (giant marine scorpions). Ammonites are not arthropods but molluscs.
