Brachiopods fossils
Trilobites, like brachiopods, crinoids, and corals, are found on all modern continents, and occupied every ancient ocean from which Paleozoic fossils have been collected. The remnants of trilobites can range from the preserved body to pieces of the exoskeleton, which it shed in the process known as ecdysis.They are either body fossils or trace fossils of marine invertebrates. Most of the diversity comes from corals and brachiopods. In terms of abundance, crinoid columnals (pieces of the “stems” of sea lilies) are frequently found, but columnals are hard to attribute to species so we know very little about the actual kinds of crinoids that they came from.

From Wikipedia: Brachiopods "are marine animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs.
