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.
How old are trillabites?
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.

Why can trilobites be used as index fossils?
Trilobites: The Index Fossil There are many thousands of known species of trilobite fossils found worldwide. Trilobites are considered to be good index fossils because they evolved so rapidly, and this allows geologists the ability to date the rocks in which the trilobites are found. The discovery of trilobites is second only to the discovery of dinosaurs, and new species of trilobites are still being discovered today.
