Trilobite Habitat. The Trilobite was a marine animal, meaning that it lived in “salt water,” but certainly Paleozoic Era “salt water” was chemically much different than that of today’s oceans. Fossils have been found in rock formations that indicate a wide range of temperature, from shallow tropical seas to deep, cold ocean shelves.Trilobiti (název podle těla tvořeného třemi laloky – prostředním a dvěma bočními) jsou třída vyhynulých členovců patřící do vyhynulého podkmene Trilobitomorpha – jsou jednou z jejich vývojových větví.
