Geisonoceras has an orthoconic shell with transverse lirae and striae that are periodically thickened.

Trilobites are hard-shelled, segmented members of Arthropoda and the class Trilobita that existed throughout almost all of the Paleozoic era, flourishing in the earlier part of it and slowly declining in the later part. The most common trilobites were about 2-7 cm (1-3.5 in) in length, but over their long history they ranged in size from 1 mm-72 cm (.04 in-28 in) and exhibited so much variation that they are classified into nine (or possibly ten) orders with more than 15,000 species. The smallest species are presumed to have been part of the free floating plankton, while the more common, mid-sized species probably walked along the sea floor filtering mud to obtain food, and the larger varieties may have been swimming predators.

Coral is built by secreting calcium carbonate skeletons. Hard coral is fossilized over millions of years. It can be almost any color. The stony Corals are often found in Coral reefs, large structures generally found in tropical waters. Reefs are extremely diverse consisting of over 4,000 species of fish, cnidarians, mollusks, crustaceans, and other animals.
