When did trilobites live.
Trilobites, at the height of their reign, existed all over the world. Almost every modern continent had a trilobite population nearby, and there weren't many places that didn't have some species of trilobite occupying at least a small part of the local ecosystem. That doesn't mean they didn't have some favorite spots, though.
What did trilobites eat? Trilobites occupied a huge set of habitats and paleolatitudes, from tropical shallows and reefs, to polar depths, and wide-ranging pelagic habitats in between.Their diversity of form suggests a complex ecology with many modes of life, including occupation of a variety of trophic (feeding) guilds.There has been a long history …May 6, 2022 · Related: Why did trilobites go extinct?

Trilobites first appeared during the Cambrian Period (about 520 million years ago) and disappeared at a major extinction event at end of the Permian Period (about 250 million years ago).
The oldest trilobite body fossils around the world, at or near the Terreneuvian–Cambrian Series 2 boundary (ca. 521 Ma), already show established diversity, phylogenetic disparity, and biogeographic provincialism (11–13). This, among other evidence, has been used to suggest that trilobites had a much earlier, Precambrian origin (e.g., refs.

First appearing in the early Cambrian Period (some 542 million years ago), the now-extinct Trilobite is one of the earliest-known arthropods. The name, meaning ‘three lobes’, is aptly descriptive of the marine animal’s distinctive 3-lobed, 3-segmented body type.
The Trilobite Family. Trilobites were early examples of arthropods, a vast invertebrate phylum that today includes such diverse creatures as lobsters, cockroaches and millipedes.
