They died out at the end of the Permian, 251 million years ago, killed by the end Permian mass extinction event that removed over 90% of all species on Earth. They were very diverse for much of the Palaeozoic, and today trilobite fossils are found all over the world.
What caused the trilobites to go extinct?
It was at the end of the Paleozoic Era that the trilobite disappeared. For years the trilobite's extinction had been blamed on a sudden increase in the numbers of trilobite predators. ... Other theories linked to trilobite extinction include climate change, sea-level fluctuation, and even the effects of meteorite impact.
What preyed on trilobites?
Nautiloids were probably important predators of trilobites. Trilobites certainly were important prey for larger creatures. At first these were large invertebrates, such as predatory worms, nautiloids, sea scorpions (eurypterids), crustaceans, and perhaps Anomalocaridids.
