Other marine invertebrate fossils found in Triassic rocks, albeit much reduced in diversity compared with those of the Permian, include gastropods, bivalves, brachiopods, bryozoans, corals, foraminiferans, and echinoderms. These groups are either poorly represented or absent in Lower Triassic rocks but increase in importance later in the period.Few morphological features in the entire fossil record are as singularly significant as trilobite eyes. By the time the initial members of the trilobite line appeared early in the Cambrian, slightly more than 520 million years ago, many of those arthropods already featured highly developed eyes -- marking them as the first creatures to leave behind fossil evidence of such a major evolutionary ... ….

Further, the App provides content for major groups of invertebrate fossils from four major time periods and geographic regions in the United States: the Ordovician of the Cincinnatian region, the Pennsylvanian of the Mid-Continent, and the Neogene of the southeast, as well as invertebrate and vertebrate groups for the Cretaceous of the American Midwest and High Plains, just as the website ...At least 3,500 living species and 15,000 fossil species are known. Bryozoans are small animals (just large enough to be seen with the naked eye) that live exclusively in colonies. In fact, the Phylum Bryozoa is the only animal phylum in which all known species form colonies. The name comes from two Greek words, bryon (moss) and zoon (animal ...Fig.1.

Corals are cnidarians that live as polyps attached to the sea floor. Polyps of modern stony (scleractinian) corals produce a hard skeleton that is easily fossilized.
